Grand Summoner Abraxeton was a high-ranking member of the Burning Legion who served under Gul'dan during the Battle on the Broken Shore. He was defeated by the combined efforts of Alliance and Horde adventurers during the battle, but was re-summoned and ordered to aid Legion forces in Suramar.
Despite his continued efforts, Abraxeton was again slain, this time as part of the quest The Black Tome. He held the book that loaned its name to the quest, part of a chain involving Kyrtos and his quest for greater power.
