Velber 02

, True Name , is the second of three Void Cells deployed by the Velber in 12,000 BC. She is the original form of Altera in Fate/EXTELLA.
==Profile==
===Identity===
Also known as the White Titan of Tassili n' Ajjer, is in history the Great God of Sefar.
She is Velber 02, also known as the , or the Ark of the Stars, one of the ships that surround the main Velber "Harvester Star." The ship entered the solar system with her "older brother" and "younger sister" fourteen thousand years ago, Velber 01 and Velber 03, and she eventually landed on the Moon. She invaded the Moon Cell and Earth simultaneously, becoming known as Sefar.
She invaded SERAPH as an Anti Cell, and also sent her own data to Earth to create a material body (avatar), invading both at the same time. She did huge damage to the Moon Cell but was ultimately beaten; however the Moon Cell had no way to wipe her out and thus she was sealed away. The Altera (Moon) stayed in the Star of Tears which became the separated territory known as the "Zero Dark".
On Earth, Sefar destroyed most of mankind's earliest civilizations, including Atlantis in an event that would be remembered as the Leukosmachia. Because the Twelve Machine Gods of Atlantis abided by their territory, they were unable to defeat Sefar by themselves whilst they would have as a group. Sefar in particular claimed Ares' personal sword as a trophy, after which the remnants of the gods survived minus their true bodies. Before Sefar could destroy the world, she was killed by the wielder of the holy sword on Earth.
Her corpse became the basis for several beings such as the Gigas who fought in the Gigantomachia and the Valkyries (such as Brynhildr) who became Odin's daughters. Karl der Große encountering the mummified remains of Sefar in the Alps gave him his desire to unify the world, and Astolfo describes how after coming in contact with Sefar Karl became like a different person. The core essence of Sefar's body then became the Altera of Earth who would be eventually found by the Huns. On the Moon however, 14000 years past and Altera of the Moon wakes up as the Velber approach the galaxy again.Fate/EXTELLA Story and Lore (free range spoilers), Translated by Rannoncap (While in the first part of Extella it is said that Altera stirred of her volition… but in truth, it was Archimedes who roused her.)Fate/EXTELLA material - Altera, p.008

Within the History of the Atlantic Lostbelt, Zeus forcibly assimilated the authorities of his fellow Machine Gods in order to fight Sefar. He fought her to a state close to a draw and repelled her in event known as the Leukosmachia. Afterwards, Sefar's remnants, known as Gigas, were defeated in the Gigantomachia.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountain City, Chapter 1
====Avalon le Fae: Fae Round Table Domain====
In the history of the British Lostbelt, the fairies never forged Excalibur simply because they were too lazy to do so. With no way for Earth to fight back against Sefar she was able to succeed in her goal of destroying the planet, leaving nothing but ocean behind.Fate/Grand Order: Cosmos in the Lostbelt - Avalon le Fay: Fae Round Table Domain, Chapter 27
==Abilities==
Sefar is an enemy beyond humanity, beyond this solar system, beyond this universe. A being from the outside of space itself sent by the Umbral Star to act as its Vanguard. She is a standard type of Anti Cell built to physically destroy civilizations with raw power alone. Furthermore, she absorbs Magical Energy from the civilizations she destroys and uses it to grow bigger, only to destroy itself once the task is done. Archimedes states that Sefar not only endangers the continuation of SE.RA.PH, but “all of existence as humans comprehend it.” Humanity itself. Earth, the Moon, everywhere humanity lives and breathes, its lives, its dreams, its cultures. Although the Moon Cell treats most human conflicts impassively, Sefar is the only being whom the Moon Cell considers a threat to itself. The last time Earth encountered Velber, 80% of the planet’s surface was burned to ash. Out of all the beings that lived on Earth during 12,000 BC, no one could have beaten the White Titan. Sefar killed more than the plants, animals, or humanity. Sefar killed beings older and greater than Gilgamesh himself, the very personifications of nature and other world concepts. Not even those who were worshiped as gods stood a chance against her, and were simply crushed one by one right alongside their followers. 
Sefar is an Anti-Foreign Civilization, Anti-World Weapon.
 Because she has a bonus modifier against the World, gods who embody the aspects of nature are at a disadvantage against her. Most god's Divinity comes from Earth, but the Sun belongs to the universe. In terms of raw force, Tamamo-no-Mae states that Amaterasu could be on par with Velber. However, Tamamo later on stated twice that she had been among the gods that were vanquished by Sefar. When Sefar was finally released in the Moon Cell, she stated that there is no way to stop Sefar, and that she had known she wouldn't be able to save Hakuno Kishinami all along. As the embodiment of the Sun, Tamamo knows everything that happened 14,000 years ago. Thus, she admitted having lost to the White Titan before, and that she knew in her very bones that they would be no match for the Umbral Star. The Heavens, the Earth, the Sea, the Sun, Fire, and the Forest. All of their wisdom came to nothing. The titan rejected all reason, all love. It even rejected Death itself. Only in the Atlantic Lostbelt, where Zeus forced the other Twelve Machine Gods to fuse with him, were they powerful enough to fight Sefar in what was approximately a draw and repel it. In Proper Human History, where the gods acted prideful and underestimated Sefar, none of them were able to prevail and thus, Atlantis was destroyed too. Not even the very embodiment of War, with its great sword, who was said to be the greatest enemy she had ever fought, was able to touch Sefar. 
In 12,000 BC, Sefar was not defeated by a god, but rather, a mere human. As she struck down Ares, IT appeared. A single sword, forged and refined in the depths of the Earth. The Ultimate Phantasm, created by the stars and humanity's deepest wishes. The embodiment of world-saving hope. Although similar to the own sword Sefar was holding, this one was smaller, small enough to be carried by a human. Despite Sefar’s body being tougher than any stone on Earth, strong enough to resist the heat of stars, her body was split in two by the Holy Sword. Its light was so big and bright, that it nearly swallowed the titan whole. In the British Lostbelt where the six Great fairies failed to forge the Holy Sword, All of Earth's civilizations and landmasses were wiped out by Sefar, leaving just an endless ocean behind.
Sefar's base form is that of Titan Altera, the one trapped in The Zero Dark. Even in this form, her skin is so durable that even all the power of an A-rank Noble Phantasm is unable to blemish it, let alone make her twitch. In this form, she is also stronger than Hero Altera, and it is noted that she could easily defeat two Top Servants summoned by the Moon Cell on her own. Gilgamesh states that if Altera were to transform into the White Titan, she would stand a fair chance against him, and that it would be worth using Ea against. When Altera finally transforms into the White Titan by the end of each route, she only gets to manifest her 3rd stage. Elizabeth Void states that this is just her hatchling state, and that the more she destroys, the bigger she will get. Even then, her scream alone can tear everything apart, seemingly shaking SE.RA.PH itself. Hakuno Kishinami states that it is so primal, so tremendous, that it resounds across the infinite void of space. Archimedes states that her power in this form is far beyond that of any Servant. In fact, Hakuno states that she could shred entire territories at will, and that compared to her scream, Altera’s army, which was comprised of Gilgamesh, Iskandar, Jeanne d'Arc, and Altera herself, is nothing. Being the Moon Cell's ultimate doomsday device, Artoria Pendragon was summoned by it to cut down and kill Altera with Excalibur should she become too much to handle.

*Crest of the Wandering Star (??? Rank): An exclusive skill of hers. It is the ability to turn into a giant god in order to destroy civilization, her fundamental design. With this passive skill, the lives, structures, and concepts she destroys are absorbed as Spiritron information and she increases in size. In the Early Dawn Territory/Zone, she is 16 meters in size, but that's only because her default height is set to be "10x the size of the people native to that civilization". In this environment, she consumes Spiritrons to accelerate the rate of her growth. There was a limit to how large the Alter Ego of the Titan Altera could grow on Earth in relation to its gravity, but there exists no such limit in cyberspace. That being said, her movements slow down if she becomes too massive, and since it takes time for her thoughts to be communicated to her peripheries, it’s thought that she manually optimizes her size to facilitate easier movement. Altera cannot by her own will remove this skill. By absorbing an amount of Magical Energy equal to her current HP amount, her maximum HP doubles. Further, due to her modifier as the Titan, whenever her structure reaches a size double to the previous (16M, 32M, 64M, 128M, 256M, 512M, 1024M) she will advance to the next stage, and all of her parameters are increased by 1 digit. For example, if STR A is equal to a value of 150, and a + doubles that to 300, then with the Titan modifier, what is 300 at first stage, becomes 3,000 at second stage; 30,000 at third stage; and so on, becoming 300,000,000 at her seventh stage. This approaches Gold-Fur White-Face in her nine-tailed form (387,420,489) - an amount of energy on the level of a sun.

Sefar (2nd stage) 	3,000
Sefar (1st stage) 	300
A rank Strength 	150
*Magical Energy Absorption (??? Rank): Another exclusive skill of Attilaight Cell. The body of the Titan, composed of Spiritron collectors, will unconditionally absorb "Magical Energy processed into techniques" and covert it into HP and Armor values. Techniques equate to skills, knowledge, and civilization. To an Anti Cell, there is no better form of nourishment. Any form of attack (interference) designed by intellect - however undeveloped the theory behind it may be - will only grant more power to Altera. The large firepower of greater magecraft and strategic weapons of science and technology will fuel the fire further. On the other hand, while pure magical energy - what can be called life-force itself - will also be mostly absorbed, it can still exert its regular effect. Facing against an Anti Cell, it comes down to simply "bludgeoning" it. Although this is a troublesome skill that can absorb even physical attacks boosted with Mana Burst, there exists one thing can deal an effective blow. The energy discharge of the holy sword Excalibur. The White Titan that had once appeared upon the surface was repulsed by the holy sword tempered in the inner sea of the Earth.
===Noble Phantasm===
Before Sefar was defeated by the Holy Sword 14,000 years ago, before she fell to the ground, she had a sword in its hand. Photon Ray, also known as the "Sword of Mars", originally belonged to the God of War, Ares, one of the 12 original pillars of nature. Its concept comes from ancient times, back to the first primitive cutting tools. Ares was the greatest enemy she had ever fought, so after she defeated him, she took his sword as a trophy. When SE.RA.PH noticed that she had become a sword wielder, she changed her class accordingly. Furthermore, the Sword of Mars also became part of her core, and as a result, she gained the power to manifest it at will, just like how any object Hero Altera holds becomes Photon Ray.
