Not to be confused with Yayap.
Yapyap rose through the chain of command within the Banished due to being slower than the other Grunts at avoiding eye contact when a job needed to be filled.
After discovering the Throne of Woe, Yapyap rebelled against the Banished in favor of locating the fabled Golden Methane Hydrate Mines of Sabator, hidden somewhere on the Ark. Throughout his rebellion, the Throne of Woe continued to communicate with him, telling Yapyap that the Ark belonged to the Unggoy. Yapyap managed to lose more Unggoy in battle than were even carried to the Ark in the first place. The Throne of Woe would somehow produce Unggoy reinforcements for Yapyap after he argued with and kicked the Throne.
