Diyu

Diyu was once a goddess who reigned supreme amongst the alien pantheon of the now-extinct Diyunian Empire - she would betray her fellow gods during a raid from demonic forces and absorbed the powers of the fallen pantheon into herself, making herself immensely powerful but also driving her to insanity.

Diyu would be banished to the lower-planes of existence following this betrayal and watched as her followers perished, leaving her a lone entity desperate for attention - this desperation would merge with her madness to turn her into a demon that was obsessed with sensation and lust, traits which have become Diyu's trademark ever since.
