Erminti is a rogue who, along with Arkes, found herself in the Shadowfell with no memory of how she got there. Surviving for three harsh months, she and Arkes were able to escape to the Material plane through the portal that is pouring monsters into Waterdeep from the City of the Dead. She has been in Waterdeep for six months. The two rogues are extremely close.
She is a capable fighter, and is resistant to psychic damage from Shadowfell creatures.
Renaer Neverember took Erminti in and brought her back to health, and the rogue has decided to stay in Waterdeep to assist the resistance. Of Arkes and Erminti, she is the tougher of the two.
