The SharpClaw originated from the second moon of Sauria, which crashed into the planet and became known as the Moon Mountain Pass. Eventually they left their home and spread all over Sauria. It is unknown what happened to them when they betrayed Scales but during the Aparoid Invasion on Sauria, Slippy mentioned that they were wiped out. Most likely the survivors withdrew to one of the ancient catacombs or temples and dug in.
