Rebka was born and raised on the planet Teufel, of the Phemus Circle, and is often known to quote the most famous saying about Teufel, "What sins must a man commit, in how many past lives, to be born on Teufel?" He also occasionally reminisces or relates situations to childhood experiences of growing up and learning to survive on Teufel. In particular, the task of retrieving water as a child while facing the Remouleur dawn wind, which would have killed him if he hadn't timed every move exactly.
