Avici

Avici is a creature spoken of in the legends of the Ankes and seen as an enemy of Pandemonium, though she is infinitely less powerful than the supreme being - indeed it is Avici's imperfection which drives her and in many ways she is envisioned as Pandemonium's opposite.

A being of order she wanders the cosmos and seeks to bring eras of peace and tranquility, yet in the process she causes stagnation as worlds are denied the chaos and destruction which is necessary for life to fully develop - eventually this stagnation causes horrific mutation and depravity (compared by the Ankes to the effects of long term inbreeding).

Unable to admit that her ways are flaws Avici abandons such worlds to their fate and continues her path of ruin, seeing herself as superior even to Pandemonium and unable to understand why so many oppose her "aid".

Despite Avici being a creature of order she is known to be a part of the Five Lords of Malice and frequently works with the other Lords of Malice, who are far more chaotic in thinking than she is - due to this Avici's pride once again acts up and she often sees herself as the only Lord of Malice with any true sense and plays along with the others only out of a desire to someday surpass them and become the supreme being she knows she is..
