Star Wars - Sovereign of Rage

Karn Valis, a rare Sith pureblood with a past drenched in chains and blood, was never meant to be free, let alone powerful. Raised in the shadows by Darth Sidious and placed under Count Dooku's eye alongside Ventress, Karn walks the razor's edge between wrath and control. His lightsaber howls with the fury of a Krayt dragon, and his rage burns brighter than any Jedi hope.

But he is no apprentice. He is a weapon.

And weapons eventually turn on their makers.
