Kain Darkwind's Savage Tide
Bone Lord Malagon
The Bone Lord reappeared when Katrina was trapped in Hell, called forth to protect her when Vuall, Duke of Pleasure, attempted to do her harm. It was revealed that Malagon is an undead pit fiend and a Duke of Hell, with most of his crew comprised of undead devils as well. He revealed that he now regarded Katrina as in his debt, having also secretly aided in her rescue from The Void.
