After the incident on September 25, 2230, guards and convicts at the POC were forced to work together. Xavier, the informal leader of the convicts, partnered with leading security guard Joss Blaney. He seemed to have knowledge of the Yautja, acknowledging their involvement after Blaney showed him blade marks and plasma burns. At one point, he apparently hurt Blaney's lover, Natascha. Most likely, he died around the time the USS Verloc crew arrived.
