Kagen the Damned: 1

Kagen Vale is the trusted and feared captain of the palace guard, specifically charged with protecting the royal children of Gessleyn, 89th queen of the unbroken line of the Silver Lands. But one night, while Kagen is drugged by a woman in a tavern, the Silver Lands are overrun, and the entire royal family is killed and burned as a sacrifice to the dark gods of the immortal Witch-King. The once-thriving kingdom is in ruins, and the people are enslaved. Haunted and broken, Kagen becomes a wanderer, working odd jobs and trying to take down as many of his enemies as possible, when he hears a rumor that the royal twins are still alive, and possibly being raised for dark sacrificial purposes. Kagen makes it his mission to hunt for the royal children and fulfill his oath to protect them, and train them to begin a campaign to reclaim the throne. As he hunts for the children, Kagen's quest takes him to strange lands where he encounters the supernatural in all its many bizarre and terrifying aspects.
