**The Mercury** (水銀, *Suigin*?), better known as **Mercurius** (メルクリウス, *Merukuriusu*?), or **Karl Ernst Krafft** (カール・エルンスト・クラフト, *Kāru Erunsuto Kurafuto*?) is the **Fourth Heaven** and the central antagonist of Dies Irae. He is also the closest friend of Reinhard Heydrich.

He is the Vice Commander of the Longinus Dreizehn Orden and occupies Seat XIII of the Table; despite the fact that he granted them their power, all of the Knights fear and despise him.

## Appearance

Mercurius is a androgynous man with long dark blue hair. He is noted to greatly resemble both Ren and Lotus. His sensories all share the similiar looks as him, albeit with a minor differences.

## Personality

Mercurius strives to achieve the unknown, not because he wants to learn more, but because he is hopelessly bored. He naturally possesses a relaxed and manipulative demeanor, something that infuriates virtually everyone that he come into contact with.

He is led by his heartfelt wish to experience the unknown, and all his actions are carried out in order to bring out such unknowns, expecially that particular end. He does not interfere directly with the World, and simply throws pebbles, and watches the ripples that issue out. Small changes that lead to grand outcomes. Despite his nature as God, the Man Pulling the Strings, he is in fact an honest person. Who never goes against the promises that he makes.

Despite his sadistic streak, he is fundamentally a pure man, giving birth to the Cycle of Eternal Recurrence for the reason of dying in the arms of the woman he loves, and for the creation of an ideal future.

He though is arrogant and controlling, for he says,

**"I won't accept anything other than what I want"**

If such an undesirable end occurs, he would cycle the World once more.

He has become detatched after the countless cycles, and only feels companionship for Reinhard and Marie . Thus his desire for an Ideal Future began to fade away, leaving him with the sole desire to die in Marie's arms.

He is stated to be the most responsible of the Gods, for he is the one that takes the future into account more than any of the previous Gods.

## Story

### Before Dies Irae

Mercurius originates from the world of Zoar.

While details are unknown, he was decribed by Kouha as a "bug" in The Morning Star system, becoming the Mercurial Snake was able to reach the Throne by taking advantage of the time paradox that Nerose Satanael created at the end of Paradise Lost, using Sequere Naturam to atomize the Hegemony God in a single hit.

After attaining the throne, Mercurius's law originated the world of Omega Ewigkeit, in which time looped endlessly. It is unknown what his original desire was, though it is implied that he wished to know all things. His law also allowed the concept of "possibility" to enter the throne, creating the multiverse.

He eventually created the Die Ewigkeit style of sorcery along with several others.

In 1775, he, through his sensory Alessandro di Cagliostro, ventured to a remote German village in the late 18th century and freed an imprisoned Anna Maria Schwagarin from captivity, slaughtering her guards. He then taught her several styles of sorcery before disappearing.

Growing bored with the eternal recurrence, Mercurius began searching for a way to die. It was during that search, that he, as Cagliostro, found himself at Marie's Twilight Beach. Instantly falling in love with Marie, he decided that she was the person most fit to kill him and take the throne. However, as she was a Transcendence god, not a hegemony god, she could not take the Throne for herself, so Mercurius began crafting a plan to both kill himself and change Marie's desire to transform her into a Hegemony god.

## Powers and Abilities

As a Hadou God Mercurius is transcendent of, and has power over, all of Creation. For all things in the infinite multiverse are governed by his Laws, the World is not but his Canvas. For he commands all concepts and phenomena in the universe, and exist unbound by time., and he exists completely above and external to all expansions of the Singularity - of which size corresponds to the inner depth of the Throne God, reaching up to infinite levels each transcending the last - which in turn utterly transcends the Multiverse, no matter the qualitative dimensions/layers it may have.

Without being granted control by the Throne his Hadou will flood the entirety of Creation. In essence this means that Hadou will encompass anything and everything regardless of scale. Be it from a singular universe, to a dimensionless space such as the Throne. For  a Hadou God is a walking Atziluth, one who defines its own boundaries and it infinitely expands its Craving until everything in setting has been subjugated to their Law. In short, "Hadou God is the Godhead. I am everything, everything is me".

Even the weakest of Hadou Gods with 1 Taikyoku exist external to all expansions of the Singularity, and Mercurius has a value of 90, making him one of the strongest possible Hadou Gods. Enough so that he was able to kill the previous God, Nerose Satanael, in only a single hit.

As he is the Throne God of Omega Ewigkeit he exists as the Alpha and the Omega, the Beginning and the End, Everything and Nothing, he is the all-encompassing whole that precedes even duality itself.

He is known for his massive expansion upon the World of Atziluth-Tai, turning it from a singular universe into an infinite multiverse. Every reality subjected to his Cycle of Eternal Recurrence

Though unlike the Godheads both before and after him, he is not capable of using the Memory of the Throne due to his paradoxical existence.

This law is able to activate itself even after Mercurius's death, rewinding even the throne, which exists outside of time. Upon meeting and falling in love with Marie, a loophole formed in his law. The only way to permanently deactivate it is to fulfill Mercurius's wish, to die while experiencing Marie's embrace.

### Sequere Naturam

(*You Are to Follow Nature)* Mercurius first gathers thousands upon thousands of stars into one point before condensing into a single blast. This attack is powerful enough to atomize Nerose Satanael, a fellow Hegemony God, with a single hit.

When he intentionally emanates this aura it is enough to completely break people, driving Shirou Yusa to madness during the meeting in Gladshiem over the events of Kei's Route.

This Aura is a result of his Law of Foreknowledge.

### Disce Libens

## Trivia

* Mercurius has held the throne longer than any other god.
	+ Because Mercurius's law caused the world to enter a continuous loop, it's impossible to tell how long he sat on the throne or how old he actually is.

* Most of Mercurius' names have to do with either medicine, alchemy, astrology, and astronomy. Usually being ether the father of, or an important figure in, one of these fields. Those that aren't are associated with magic.
	+ Karl Ernst Krafft, Alessandro di Cagliostro, Paracelsus, Albertus Magnus, Saint Germain, Christian Rosenkreutz, and Johaan Georg Faust are all people with actual historical roots.
