Possibly the last survivor of the Demonocracy.
LADY OF THE FORKED TONGUE
LAST OF THE HIGH FIENDS
SENESCHAL OF THE DEMONOCRACY
KEEPER OF THE SECRET WHICH MUST NOT BE LOST
When a powerful demon is slain in this world, its soul cannot pass back to the abyssal plane that spawned it, and so its intangible remains continue to poison the world. Ashima, however, was spared by Trigenes’ purge of the Demonocracy when she offered to give guidance on how to find and trap the essences of her fellow fiends. Some might call this a betrayal, but she believes the war was already lost, and she did not look forward to oblivion.
Now she is the prisoner at the center of the Clergy’s Vault of Heresies. She holds a powerful secret: a ritual that can give physical form to a belief. According to her, this ritual was given to a pair of individuals long ago, a great thinker of a man who desired great change, and an eladrin mother who desired great justice. Both hated the Clergy, and Ashima hoped the ritual would be put to use in ending their corruption forever, but instead it ended up obliterating their most powerful enemy, the eladrin race. The ritual called Srasama to this world, and while her Malice cursed the blood of the Clergy leaders and transformed their country into an eternal dead-magic zone, she did not destroy them even half as well as it destroyed her own people.
Ashima-Shimtu wishes to know what happened. And from now on, she will never again speak of the ritual to anyone, fearing its power. The ritual, after all, is a relic of demonkind—and the faith of demons is fickle and fleeting. The faith of mortals, however, is vast and unwavering, giving immeasurable strength to the manifestation called.
Unlike a typical demon, she does not seem to desire widespread destruction and chaos—if she did, she would likely give the ritual to anyone who asked. Instead, she continues to languish in her chains, protecting the secret from the people she hates the most. Having seen greatness in the constables, however, she has shared these small yet troubling truths of the world, hoping they will learn more of the cause of the Malice in time, and protect the world from calamities yet to come…
