Yusdrayl is a kobold sorceress, and leader of the small tribe inhabiting the Sunless Citadel.
She had an arrangement with Durakka, providing him with kobolds for his mercenary gang but after meeting the Raiders of the Lost City she terminated this agreement to enlist the adventurers' aid in defeating the Orschans allied to Belak.
After the Orschans invaded again with the support of Cynidiceans, Yusdrayl's tribe was driven from the Sunless Citadel and took refuge in Ashinana's Oasis. There they took over the running of the Dancing Tabi after the death of its owner. Yusdrayl became the innkeeper and was in charge of the establishment's day-to-day operations.
