I put some info on them in another thread (planet #2019).
Here's more info, but it'll be in multiple posts due to mobile's limited character limit.
The Sage Overgoddess is named Yleven Cero. Lazy yet her weakest spell can destroy entire cities, so she has to hold back... in her stockinged feet, she's 6'7", but she wears high-heeled thigh-high boots with thigh-high stockings, apparently.
Kim made this character so she probably approves of Sages?
