During the Cold War, the reconstituted Sith Empire discovered a collection of prototype regenerative armor. This discovery occurred amid wreckage from a starship crash on Hoth. The armor had the capability to revive its user from the brink of death. Following their analysis, the Empire entrusted the armor to White Maw Captain Valon, tasking him with launching attacks on the Galactic Republic. Yet, Valon's ambition grew beyond his orders, and he plotted to seize control of the White Maw using the armor's power. Ultimately, the Barsen'thor of the Jedi Order intervened, shattering the armor by repeatedly and severely wounding Valon.
