Ankhseram

Ankhseram (アンクセラム Ankuseramu) is the god of life and death.

History
Sometime over 400 years ago, Ankhseram cursed Zeref Dragneel with the Contradictory Curse as punishment for him trying to devise a way to bring his brother, Natsu Dragneel, back to life.

Magic & Abilities
Ankhseram Black Magic (アンクセラムの黒魔術 Ankuseramu no Kuro Majutsu): As the god of life and death, Ankhseram has the ability to inflict this Magic, also known as the Contradictory Curse (矛盾の呪い Mujun no Noroi), on anybody, as is the case with Zeref, who became a victim over 400 years ago. This curse makes the wielder immortal and causes them to emit a black miasma, killing everything within a certain radius around them. The only way to stop this is to forget the value of life.
