Hekarti

Hekarti is the goddess of conjurations and Dark Magic. She has no shrines, save for a small temple within Ghrond's Dark Convent. She sees all the Winds of Magic and has six arms to carry her sacred accountrements -- a serpent-headed staff, a beating heart, a scorpion, a broken arrow, a serrated dagger and a phial of orphan's tears.

Unlike many of her kind, Hekarti pays close attention to the desires of the Elves. She is ever locked in jealous contest with her twin sister Atharti, the goddess of Pleasure, and resents her sway over mortals. It was supposedly this rivalry that first enticed Hekarti to grant wisdom to Morathi. That said, the Hag Sorceress has always kept her devotions to the two sisters in careful balance -- Naggarothi legends have many grim examples of what happens to those who favour one above the other.
