Anume learned well from the Demon Lord, taking his motto "Fear, Hatred, Betrayal" to heart and betrayed her patron when the chance arose: Having convinced him to aid her bring back her former Lord, Evil Sirant, she caused the Rift in reality to collapse the very moment Sirant had entered it and had passed halfway through, thus destroying Sirant utterly and consuming most of the ensuing power blast. "Never again will I serve", were her words as she turned, half expecting an attack from the Demon Lord. Malchaeius however took pride in this treacherous act of his star pupil, and even though vexed he was also amused. Laughing, he disappeared from the scene of havoc wrought by the collapsed rift. Whether he still plans to take revenge on this betrayal is a matter of speculation that keeps Anume on her toes, never quite trusting anyone.
When Malchaeius focused on his plans in another plane of existence, Anume took this chance to take full control of the Pillar of Souls and so became the undisputed goddess of Death. Whether she came to an agreement with the Pillar's former master, Chayesh, or whether she disposed of him in another power coup, is not known. Fact is, that she came back from her expedition to the Isle of Souls changed, more powerful than ever before.
