Yast

From gronkfinder

Yast (pronounced YAST) is a fire scamp who lives with his friends Tev and Yost near Yarma. Though as intelligent of an inventor as Tev, Yast spends most of their time incessantly arguing with Yost over anything and everything, only taking breaks to sleep and briefly indulge in conversation with new acquaintances. Despite this, the two scamps remain very close.
