Oshalla
Oshalla was a sahuagin priestess who had abandoned worship of Sekolah and Umberlee to turn to Selune after fleeing to land, and is now the artist-in-residence of the Elfsong Tavern. She was paranoid that her kinsmen were hunting her, both for abandoning them and for vocally objecting to a sahuagin king's plans to attack and take over landbound settlements in the Realms.
Nephrite and Grumph encountered Oshalla in the Elfsong Tavern when they went to see why she hadn't paid her rent, and helped encourage her to start trading her art for money. They also opted to keep her secret.
Oshalla's art is hanging in the ground level of the Elfsong Tavern, having been made available for sale; one pricy piece has sold already, helping her make rent for a few months. As for Oshalla, she herself has been traveling (with the aid of disguise self) to explore the new city she finds herself in and learn the ways of the land-bound she now lives along.
