Chiasa Amarantha

Chiasa Amarantha, previously just Chiasa, also known as Mugen or Shin, is the protagonist of book one of A Fallen God's Desertion. He is the God of the Neverending, also known as the God of Infinity, and the Primordial Concept of the Neverending. He is the Emperor of Weite, and the Supreme God.

Born the God of infinity, paradoxes, twilight, and the Primordial Concept of the Neverending, Chiasa is an anomalous existence that defies what should be possible, born from two gods of two completely opposite existences.

He was the Second Angel of Death, a title granted to him after his slaying of the previous Angel of Death, the Primordial Concept of Death, known only as Death.

## Appearance

### Current

After his ascension to Supreme God, shortly before his body was destroyed and he was sent into a realm of his creation, trapping him as a prisoner to his own strength, which is now the 10th layer of The Empyrean, his white hair had grown very long, dragging against the ground as if it corresponded to his increase in strength, his body was giving off a very bright bioluminescent glow, and one of his eye's had regained its former golden color.

The avatar he created as he was being sealed away was nearly identical to his appearance, but the hair was shorter, around the same length as it was when he was Mugen, if a bit longer. He's wearing clothing similar to his time as Mugen, but with golden and purple aspects to signify his position as the Supreme God and Emperor of Weite.

His True Body has no physical form, its more so a gathering of imaginary mass that swirls around with no intended destination, shape, or size. It has no concept of physicality, color, or existence. An ineffable, eldritch monstrosity that gives you a headache and a churns your stomach when you attempt to think about it.

### Shin

After being casted out of Heaven, and having his status as a God and Angel revoked, his hair lost it's white coloration, becoming a deep, raven black. His shirt and robe also changed, ditching the white robe, he instead wore a black trench coat, and a dark long sleeved shirt. His eyes lost their golden color, becoming a dull gray. He also no longer had the Blade of Death on his hip. Under his coat, he had a long, double-edged dagger with an S-shaped quillon.

After returning from his training in Purgatory, his hair was longer, reaching past his waist, and it had regained in white hair in response to his increase in strength, and the trench coat had lost a lot of it's deep color, instead being a dark gray because of the harshness of the environment of Purgatory wearing away it's color, it also tore the hem in several places, giving it a ragged appearance.

During his time in purgatory, he gained many more scars, a lot of small lacerations across most of his body, including one on his left ear that causes the tissue to dip inward where it was slashed at.

### Mugen

As Mugen, Chiasa had straight white hair that reached down to his shoulders, with some portions of it reaching passed shoulder-length. He wore a sleeveless black turtleneck compression shirt, with detached sleeves of the same color. He had silver wrist guards over the sleeves. He wore black pants and dark laced boots. Over all of this he was wearing a baggy white robe that is tied around his neck.

He had golden-yellow eyes with a fair complexion and a lean musculature. He had the Blade of Death at his hip, a curved saber with a swept hilt, with a black blade that seemed to writhe with the illusion of damned souls.

Numerous scars littered his body. They range in types - slash wounds, stab wounds, some of them even looking as if parts of his body were gouged.

## Personality

### Current

Post ascension to the mantle of the True Supreme God, after taking the place of Fate, he is a lonely man. Shackled by his own power in a world of his creation, he can not interact with his friends nor family. He was and is a tragic person, and he once again lost sight of who he was, upholding the actions of Fate after destroying it taking its toll on his mind.

The avatar he created as he was sealed away by himself acts the exact same way as he did after saving Alice, a kind and overly protective person who loves dearly and hates strongly, who will do anything to keep those he cares for safe.

Unlike his previous self, he is much more docile, and much less susceptible to killing others. He is a good leader, with great communication skills, and an abyssally deep ocean of wisdom that betrays his appearance.

### During his regressions

After witnessing Alice's death for a second time at the hands of Kushu, shortly before the man was slain, taking out her soul and physical form in one final blow, Chiasa's mental state regressed to almost being the same as he was during his past as Mugen, an emotionless being with no sense of purpose or self-preservation. He had lost the person he cared about the most, and it destroyed him.

Thinking on ways to continue, he had a realization. If Alice was destroyed, erased, gone, then he would simply have to go to a time before she died, and use his knowledge of the future to save her. Using his newfound power and Authority as Supreme God, Chiasa rewound the world to a previous state, not just rewinding time, but changing the effects of fate to revert the actions that had taken place. At first, he did it only to a few hours before the battle with Kushu. It failed. He did days before, failure, weeks, failure, months, years, back to his time as Mugen, all of them failed, no matter how strong he got, or how far back he went, she died. Over and over and over and over again, he witnessed her gruesome demise at the hand of the person he hated the most.

As the billions and billions of years passed, his reversions of causality drawing back to his very birth into the world, his love and desire to save Alice morphed into a one-way goal of stopping her death, changing into an obsession with the girl. His ways of attempting to save her slowly devolved from using knowledge of the future into manipulating the butterfly effect and the way cause and effect affected fate. At first it was small things, like changing decisions on where to go, what to do, what time to do them, but it quickly changed into killing different people, living his life in entirely different ways, taking completely different paths, even killing his other friends in the hope that maybe it would save her. He would do anything to save her, anything, it didn't matter how evil or cruel or ruthless he would have to be, her life was more important than all of it to him.

He lived life after life of failure and complete and utter disappointment. His hatred for Kushu and his disgust at his own pathetic weakness grew to the point where he lost all sense of who he originally was. Time was a concept he had lost understanding of, hundreds of billions of years passed him by as if he was merely blinking.

After discovering that Alice was fated to die, decreed by the Authority of Fate to perish, he devised a plan. Destroying Fate proved a difficult task, a feat that was not feasibly possible. Deciding that regardless of its impossibility, he was the God of Infinity, but more importantly, Paradoxes, and accomplishing the impossible was a paradox. Fate fell by his hand, and the world crumpled around him, going back for his last regression, he succeeded in saving Alice, and remembered who he was and who he was meant to be. A friend, a lover, and a deity that took hold of what he wanted regardless of the consequences.

### Shin

After being banished - exiled from Heaven - Chiasa (who was later given the name Shin by Alice Serena) was an aloof and extremely curious person. He had no memories of who he was, nor any memories about what had happened to him, but he had a powerful feeling, a strong vocation to gain knowledge.

As time passed, and he was slowly surrounded by companions, he learned to feel. He learned to feel worry, despair, sadness, elation, and many other new and unique emotions that he had never known existed. And one emotion that he couldn't explain, one that he couldn't understand no matter how hard he tried or searched for an answer. This emotion being love.

After his mission of self-discovery led him to Purgatory, he returned a changed person, and not just in his appearance. A soft smile always found its way onto his features when he was around the few people he had learned to care for, he got angry for their sake, happy for their sake, and sad for their sake. He also felt a strong attachment to them, and desired to keep them safe no matter what he had to do to accomplish it, especially for Alice.

### Mugen

In his past, he was practically a slave. He obeyed any orders he was given with no resistance, he had no sense of morality or ethical code, and simply did anything that was asked of him. He had no individuality or personality to speak of, he could hardly be called a person at all. He committed numerous atrocities without batting an eye - murder, torture, interrogation - whether the victim was innocent or guilty, none of it mattered.

He was raised to be a ruthless and emotionless weapon, like a tool who's only purpose was to kill anyone deemed an enemy, regardless of who it was.

Over the unfathomably long time he served as the Angel of Death, as well as the Dark Angel of Kushu, he developed a consciousness. Hearing the cries of people for mercy as they fell by his hands, the look in their eyes as they clung onto a false hope that never existed to begin with. The way some of them smiled as they died, accepting their fate with reluctant but accepting arms, and the way some of them cried for their mothers, begging for their lives, begging to be allowed to go home and see their family. Under all of these powerful emotions that soared around him, he questioned himself, and Kushu, and his actions, and the actions he was forced to do, and those he wasn't. He wondered why he was doing these things, why he did them without question or reluctance. He pondered why the Supreme God of all people would make him do all of these things that were considered bad, wasn't the ruler of Heaven supposed to be a benevolent force? A powerful and steadfast leader residing over one of the three realms of the afterlife?

He was curious. Curious about who he was, curious about what was happening around him, curious about Kushu. After forcing his way into the Forbidden Library, and gaining knowledge on who he was, Kushu's actions, his own actions, as well as about the world around them, he grew extremely angry. An omnipotent and infinitely deep hatred, at both himself and Kushu.

## Background

Chiasa was born in Heaven to Aurora, goddess of the sun, light, and daytime, and Nacht, the god of the moon, shadows, and night. He was an anomaly, born from two opposing concepts that couldn't mix - a paradox. He was born as the Primordial Concept of the Neverending, the Primordial Concepts were deities originally born from the essence of Chaos, and make up the original existences that everything else is derived from. Chiasa was born one because of his unique existence being never before seen. Shortly after his birth, the Supreme God Kushu slaughtered her parents, stealing him away from their dying grasp. He raised Chiasa under the false name Mugen, training him to be a tool for his use, something to destroy his enemies and made to be his weapon to achieve his goals. As he grew, his power grew exponentially, and soon enough, he could only be opposed by the Supreme God. Through the years of his life, he fought as a one man army, the sole combatant on the side of Heaven during the several Great Wars. Under the command of Kushu, he was a lethal weapon with no discrimination towards whom he killed - women, children, elderly, the diseased, sickly - there was no mercy to anyone he was ordered to kill, he carried out all of his tasks with a ruthless efficiency.

Eventually just killing his enemies wasn't enough, and Kushu ordered Chiasa to track down and kill the Primordial Concept of Death, and steal his Authority for his own in order for Kushu to control the realms of the afterlife and decide who went where upon death. Utilizing this, he made anyone he wanted to join his military force or subordinate go to Heaven, while all of his enemies, whether they were wicked or not, suffer eternal damnation in the pits of Hell, there was no in between, for the people Chiasa was ordered to send to the afterlife never went to Purgatory. Kushu ordered them to be sent to Heaven or Hell, for the time Chiasa controlled death, not a single soul, aside from natural deaths on the other worlds, although there was exceptions, went to Purgatory.

Through his time serving under Kushu, Chiasa was a ruthless weapon with no sense of self or ego, no emotion or personality, for he couldn't be called a person at all. However, as time passed, and extreme emotion surrounded Chiasa, such as the mourning of the dead, elation at won battles, despair as one was killed, and rage at him for killing one's family or friend, he started to develop an emotion - curiosity. A potent desire for knowledge, a want to know and understand. He slowly started to understand right from wrong, a concept that previously didn't exist in his mind, and a seed of doubt in what he was doing and in Kushu grew into a large tree within his mind. Chiasa started looking into himself, but any information he tried to gain was pathetic at best, nothing that would allow him to know about himself, thus he came to one singular conclusion; he would have to go to the Forbidden Library, a space within Heaven that held all the knowledge of the worlds, past, present, future, a fact governed by Fate that could not be inhibited nor controlled. Breaking into it proved a simple task, upon entry, he began taking in all the knowledge within the space, his thirst for knowledge never sated. It took him millions of years, occasionally leaving to complete Kushu's orders so that he wouldn't be suspicious. A great hatred was building in his heart for the man who raised him, although raised could hardly be a word to describe it. It was much more akin to torture, he had no childhood, he had no excitement nor happiness, if he ever showed signs, Kushu would beat it out of him, the scars marring his flesh a testament.

Upon gleaning the last bits of knowledge from the Forbidden Library, including who he was and who his parents were, Chiasa used the knowledge to stage a coup, begin his usurpation of the throne of Heaven. Taking an army of angels, alongside several other Seraphim who he had assisted in gaining an ego of their own, he led a war against the Kushu. It lasted for a long while, eventually being classified as one of the Great Wars, but Chiasa eventually lost. Every single angel at his side slaughtered by Kushu and his army of deities, Chiasa had his wings ripped from his back, his Authority and strength stolen away from him, sealed away by Kushu, and he was casted from Heaven in a macabre ritual with the reason of high treason against the throne of god, as well as committing sins such as Gluttony, Greed, Pride and, most of all, Wrath, that stole away his divine flesh and forced his body into mortality. Alongside his strength, his memories were taken as well.

After being banished from Heaven, his deific form ripped from him, he wandered the mortal world, with no sense of who he was, or what he was meant to be. He felt a strong desire from the depths of his soul to get stronger, and gain knowledge. Over time, he met several people, and became acquainted with them. These people being, in order, Alice Serena, Zy Adriel, Jake Darkwood, and Dylan Virgil. Through his time with them, he developed emotions once more, and continued on his journey of self-discovery. Along this journey, he fell in love with Alice, and gained a strong care for his friends.

Once he regained most of his memories of who he was, and growing in strength alongside his friends, he challenged Kushu alongside them. This battle went poorly very quickly, ending with Alice's death, Zy losing his left arm, and both Jake and Dylan mortally wounded, who both barely survived the wounds. Chiasa himself was also injured greatly, if not for his regeneration, he would have been crippled. After a falling out with Dylan, who left the group upon Chiasa wanting to go through the three realms of the afterlife to return Alice's soul to her body, and a fight with Zy who didn't want him to be an idiot and do it alone, the group of three delved into Hell on their journey to Heaven.

Battling through Hell, Purgatory, and lastly, Heaven, Chiasa and his friends managed to return Alice's soul to her body. During her time in Heaven, her body rapidly absorbed divine energy due to being surrounded by many gods and angels, causing her Spirit to evolve. Alongside her, Zy and Jake's Spirits also underwent large boosts in power because of the harsh environment of the three realms, as well as the battles they had to fight to get to this point. Upon entering Heaven after so long, Chiasa regained his Authority that was once sealed, along with the rest of his power and memory. After fighting through the layers of Heaven to reach the throne of the Supreme God, a battle ensued. During this battle, they were joined by Dylan, who, after having a Spirit Awakening during his time away from them, developed a new power that allowed him to bypass the laws of the world and the Authority that governed it, and used it to travel directly into Heaven to assist them after realizing his faults.

During the battle Kushu was defeated, and Chiasa gained his birthright, the position as Supreme God. However, as Kushu was fading away, he launched one final, spiteful attack at the person he knew Chiasa cared for the most, Alice. The attack struck true and annihilated her, both body and soul, erasing her completely. Try as he might, he could not bring her back, even with the Authority given to him as the Supreme God, he was unable to revive the dead. Dylan attempted it with the new power he had developed, which would later be called Magick, but try as he might Alice could not be revived, they weren't strong enough. In his rage, Chiasa destroyed Heaven, killing and stealing away the Authority of every god present, and slaughtering every single angel, regardless of affiliation. Once his anger subsided, he was left empty and without purpose. All of the emotion he had gained through his years with his friends was gone. Wandering across Earth for several years, he and his friends went there separate ways for the time. Eventually, they all returned to him with a suggestion.

They gave him the idea that if he wanted Alice back, like they all did, he could use his Authority the regress the acts of Fate to before Alice died. Taking this suggestion to heart, he began a series of regressions that would slowly destroy him. At first, he only did it back to a few minutes before Alice's death, but as it failed over and over again, he started going back further and further. Hours, days, weeks, months, years, it got to the point where he was reverting back to his birth over and over and over again, reliving his life again, changing the way he lived over and over again in the hopes that it would change the acts of Fate enough to save Alice. He regressed so many times to the point where he lost sight of who he was, gaining an obsession with Alice that led him on a one-way road to self-destruction in order to save her.

Through the regressions, he eventually did everything he could, changing every little or big thing he could, it got to the point where he was killing his friends in the hopes that them not existing would save her. Nothing worked. However, the small hope that lingered within the recesses of his soul eventually grew bright, as on one of his regressions it was different. Things were different, everything was different. This was not possible. He had done everything, changed everything, tried and failed everything an infinite number of times. And yet this time it was all different. He gained hope that maybe Alice could be saved this time, and he was sure that she would.

## Abilities

### Authorities

#### Authority of the Neverending

Chiasa's original power, the Authority bestowed upon him at birth. it allows him to control the concept of the infinite, deciding what is infinite, what isn't, and applying the unfathomable concept of infinity to reality. He can do things like increase his strength to be infinite, make his speed infinite, grant immortal life, give himself infinite spiritual or divine energy, etc.

#### Authority of the Dead

Originally belonging to Death, it was stolen upon his demise at the hands of Mugen on the orders of Kushu. It allows for manipulation of the forces of death, inducing death, controlling ways of death, and what classifies as being dead. He also directs dead souls into the realms of the afterlife, deciding who goes where, a position that is later taken by Mugen, later Azrael, after his death.

#### Authority of the Supreme Deity

Also called the Authority of the Supreme God, it is the sovereignty over Heaven. It grants control over Angels, Heaven, and the natural laws that govern the world, as well as the rules placed over Heaven.

##### Authority of the True Supreme Deity

An authoritative power held only by Chiasa after his ascension. It possesses the abilities of the original authority, but also other aspects like omnipotence, omniscience, omnipresence, control over causality and the affects of Fate. It is what allowed him to be able to regress the acts of Fate and relive his life over and over again in different ways in order to save Alice.

It later allowed him to bypass the result of his ascension, which trapped him in a new dimension accessible by none but himself, and inescapable even for someone with the powers he possessed. It ignores the laws of nature, the authorities possessed by other powerful individuals, including the Primordial Concepts, Primordial Angels and Demons, and Chaos.

#### Authority of Fate

After Chiasa's slaying of Fate, he was left to pick up the job of the now deceased force of nature. He is now responsible with deciding the happenings of all of existence, controlling what happens, what doesn't happen, and how cause and effect occurs.

#### Authority of All Desires

Originally belonging to Dahlia, it was stolen by Chiasa after she was killed by Ama. It allows for absolute control over all emotions, instincts, feelings, senses, dreams, and reality. It can be used to transform one's mind from fantasy to reality, create illusions so powerful that they're indistinguishable from reality, control what a person wants, and how their body reacts to different events. However, the main ability of this Authority is to control existence as if it were merely a book, and you were the author. Erasing things as if they never existed to begin with, creating things that have no right existing, increasing one's strength, decreasing the strength of others, giving and taking powers at will, and overall giving the user absolute control or anything that exists, has existed, or will exist, with barely a thought.

#### Authority of Emptiness

An Authority originally held by the unnamed Primordial Concept of Emptiness. They were killed by Dahlia because their conceptualization directly opposed her. This Authority was possessed by Dahlia until she was slain by Chiasa. It grants the wielder the ability to control negativity, emptiness, nothingness, and the concepts that compose them. They can do things like erase matter, conceptualize emptiness, and manipulate the immaterial element of nothingness.

### Divine Abilities

#### Infinity

Technically the Authority over the Neverending, practically a sub-ability. It was used during his time as Mugen. It granted him to the power to bring the abstract concept of Infinity into reality, control the laws of nature and physics, and manipulate any phenomena that isn't ruled over by an Authority.

He could control natural laws because of his consideration of existence itself as being an infinite concept, seeing as it grows constantly and is seemingly unending. He prefers to use it to control or influence aspects of time and space, allowing him to do things like stop the movement of time by halting its progression, which doesn't directly affect time, but rather stops it for a small moment, or to shorten the distance between two spaces, essentially granting him teleportation by decreasing the distance between himself and something else. It doesn't trigger the Authority of Space because the shortened distance is immediately repaired, and overall does not affect space itself.

#### Paradox

As the god of paradoxes, Chiasa can create paradoxes, weaving the illogical and impossible into reality as simple as breathing.

#### Equality

As the god of equality, Chiasa can control what is considered equal, can induce balance to different events, and control the balance between good and evil.

#### Twilight

As the god of twilight, Chiasa can manipulate the esoteric, paradoxical energy of twilight, a combination of light and darkness.

### Spiritual Abilities

#### Unparalleled Spiritual Energy Manipulation

Chiasa has fine tuned his manipulation of spiritual energy to the point that he can surpass the control of Spirits and Spirit users without the use of a Spirit. He can form constructs, enhance his body, spread it out over a wide area, give it physical form by condensing it, and many more applications. He specializes in creating constructs by condensing a high amount of spiritual energy, and usually uses it to create lances or daggers. He doesn't have to directly use his spiritual energy to do this, and he can do it several meters around himself. This range and control only increases as time goes on and he gets stronger.

He has so much experience utilizing spiritual energy that controlling it and manipulating it has become like breathing, something that doesn't require a second thought.

#### Spirit Creation

This is more so an unintentional ability, but if he remains around a human being for a long time, especially being in close proximity, or by choice and by forcing a great amount of energy into their body, they will awaken a Spirit. He first did it during his first life, before his regressions, with Zy Adriel.

#### Life Force Manipulation

His control over spiritual energy has been heightened to the point that he can affect other bodies of spiritual energy aside from his own. He can force nature to do his bidding, absorb someone's spiritual energy by prolonged contact, and influence natural forces like gravity and the weather.

## Trivia

* He gave himself his last name so that he would have for one when he got married and ultimately had a child.
	+ Amarantha is derived from the Amaranth flower, which symbolically means "longevity, death, and immortality," referencing his position as the God of Infinity, his position as the Angel of Death, and his immortality. Another derivative for his name is from the Greek word amarantos, which means "the unfading or undying," which is a reference to his status as the God of Infinity and the Neverending.
* The name Chiasa is inspired by the word "chiaroscuro" (taking the 'chia' and 's' and then adding an 'a' at the end), but it also has a meaning in Japanese. The kanji used for his name are 知朝, with 知 meaning "knowledge, understanding, and awareness," especially wisdom, and 朝 meaning "morning and dawn," especially reign, as in the ruling of an emperor or monarch.
	+ The original meaning of his name is in relation to his lineage, being that of the goddess of the sun and light and the god of the moon, night, and the absence of light. The Japanese translation of his name, although accidental at the time, is used as a reference to his knowledge and wisdom gained from the Forbidden Library, and his age, with the second kanji used being used as a reference to his status as a deity, and his eventual position as the King, later Emperor, of Weite. Another way to spell his name is 千朝, meaning "thousand," and "morning and dawn" specifically, with thousand being a reference to his strength, morning being about his mother, and dawn being about his own symbolic position between sunset and sunrise.
* He is strongly inspired by two characters from the That Time I Got Reincarnated As A Slime light novel series, specifically the main character, Rimuru Tempest, and the legendary hero Chloe Aubert.
