Seydes

About
Seydes was the former pope of the Church of Eve, and later the leader of the Outlaw conspiracy known as the Snake Crest during both of its major incarnations. Having translated new sections of the Evenicle, Seydes broke from Mother Eve and began to plan a secret coup against the rest of humanity. Little is known about Seydes's life prior to these events. After the Arthur Tragedy, Seydes went into hiding, and began to rebuild the Snake Crest for his second offensive.

Seydes's ultimate plan involved two stages: to undo Mother Eve's grasp on the world (most notably through removing her "blessing"), and to attain the power of both Mother Eve and of the Archfiend Adan to destroy the world and thus Eve's legacy. To this end, he used the techniques Snake Crest had used to refine Adan's Blood on his own administrators, creating pure strains of six major human desires, which he then absorbed into his own body through a system of machines and pipes. He himself became an embodiment of wrath against Mother Eve.

With the unwitting help of Princess Croix of Eden, Seydes was able to both temporarily succeed at his first goal and to gather the power of Mother Eve as well. The second phase of his plan was also close to completion when he was defated by Asterisk and his family, despite transforming using his newly obtained power. The weakened Seydes's power was then drained by Prince Felton of Central, who took it to the Archfiend's Right Arm. There, Seydes manifested as a new being, the Wrathful Shadow, which Aster also defeated.

Appearance and Personality
During the days of Aster's adventure, Seydes had become a withered and hateful old man, already changed by the process of absorbing others' desires. He is never seen without his snake-themed throne and its contingent machinery, even in his human form as the Wrathful Shadow.

Seydes was once fantatical in his worship of Mother Eve, but this zeal turned to wrath after he learned more and more of the truth about Eve and the Archfiend Adan. Unwilling to support Eve's world any longer, he delighted in turning the members of the Snake Crest against one another, not only to create the desires and circumstances that his plans required, but quite possibly out of sheer glee. His love of suffering was what ultimately led him to attack Aster and his family at all, when he could otherwise have simply hidden behind a force field he had prepared for his own protection.

Once transformed, Seydes's jaw was said to have unhinged like a snake's to reveal his new form within: a four-armed being with a skull for a face, spikes protruding from the body, and huge pustules along its back.

Abilities
As former pope of the Church of Eve, Seydes can be presumed to have a thorough understanding of religious matters, one only enhanced (to his misfortune) by his translation of the Evenicle. His administrative and manipulation abilities have only been refined by his time in Snake Crest, having organized not just one but two conspiracies against the rest of the world, both of which nearly succeeded. As royalty after a fashion, Seydes may have similar, knight-like powers to other members of nobility in the World of Eve, but this has not been confirmed.

Once transformed, Seydes gained an unparalleled physical power, but was ultimately undone by his reliance on wrath, something Aster could quell with his fighting techniques. It is unclear how far Seydes's powers would have evolved if he had survived any further after gaining the power of Eve and the Archfiend, but he had hoped it would allow him to destroy the world.

As the Wrathful Shadow, Seydes was able to repel anyone who was guilty of that particular desire (for the case of Aster's party, Ramius Dreissen, Riche Eden and Kathryn Lapucelle).

Trivia

 * Seydes' image files are named "総帥" (Leader) rather than with his actual name, which may imply that he was named late in the development process.
