Dahkath's Council of Thieves
Kibizax's yonger son Yippitok
Yippitok – who is known among the clan of Kobolds called the Sewer Dragons as Trapmaster Tok – is a skilled alchemist. During the PC’s intervention and subsequent killing of his father, Yippitok has fled the area, taking large portions of his alchemical notes, formulas, and equipment with him.
His older sister, Yiddlepode, had not told anyone of her conversation with the PCs, nor her agreement to have her father killed and for her to assume command of the Sewer Dragons. Yiddlepode is therefore likely quite angry, and may reappear in the future.
