Hekarti

The elf goddess of dark magic of the Cytharai, while Hoeth is all about learning and wisdom, Hekarti is willing to give her worshippers pure power, at a price. No gift goes for free after all.

She is depicted as having numerous arms holding various object. Kinda of like a mystic elf hindu diety.

Considering her name, being a goddess of the underworld and her focus on magic and mysteries, she is clearly inspired by the Greek Goddess Hecate who shares these similar traits.
