Caedus vs Exar Kun
Caedus learns that Exar Kun has abducted Allana and has taken her to Korriban and hid her in one of the tombs in the Valley of the Dark Lords. Caedus finds him and since Korriban is one big nexus of dark side energy, both Sith's powers are greatly enhanced. Exar Kun is armed with a double blade lightsaber and has the amulets. To make it fair, Caedus is armed with twin lightsabers. The exact combat site is in the ancient Sith Temple. Who wins?
