Rajua was the leader and main orchestrator of the Unggoy Rebellion. His name comes from the original Unggoy word for 'rationality'. He is an ancestor of Jitji.
He was among the first Unggoy in Ages to realize that the Prophets were false, and was certainly the first to do something about it. With the help of his friend Wavushi, he launched a campaign to bring the Prophets down. While one Hierarch was killed, their campaign ultimately ended in failure. Unfortunately, by the Ninth Age of Reclamation, his story had mutated into one about pious "Rajar" rallying Kig-Yar to bring down the Quelni.
