The Nameless's master

This individual was affiliated with the Remnants and the master of The Nameless, a female individual and rumored cultist of Vecna. In 812 PD, the Nameless stole secret knowledge from her master before fleeing to Gatshadow Mountain, presumably allowing her to breach the mountain's lower gates and becoming the new Herald of Oblivion.

So far, the Nameless's master has neither appeared nor been mentioned onstream.
