Rovhu's Pilot was bonded to her while the Leviathan was under Peacekeeper captivity as a prison transport. After the convoy came under Scarran attack, the ship's lone prisoner, Kaarvok, took over and used a device to "twin" the Peacekeepers aboard, eventually degenerating them into a savage, almost mindless clones that he coined the Xarai. The Xarai began to eat the Leviathan and cut off Pilot's arms, eating them as well and continuing to cut them off any time they grew back. In order to maintain control over the Leviathan, Kaarvok also slashed Pilot's neural pods, weakening his link with Rovhu.
