Velkaarn

Velkaarn is the central antagonist of Castle of the Undead and the vampire darklord of Maridrar. The Bloodknife was forged in order to slay him and despite the deaths of the princes that sought his demise, the blade drifts to their reincarnations and still operates as a Death Bane Weapon against him.

The Kara's Daughters campaign has added the following:

Velkaarn was once a proud and loyal general of Maridrar, the finest in the field. When word came back to King Jhandar that Velkaarn had fallen while defending the kingdom, he was truly grieved. But shortly a messenger arrived: Velkaarn returned as a bloodthirsty horror, his loyalty to the crown forgotten. The king sent his family into hiding, but the retainers betrayed them into the hands of the treacherous vampire. Held captive while the vampire's undead army grew from the ranks of their own servants, Queen Icanthe (a mortu Vistani) managed to help her children escape. The vampire tortured her for her insolence, but her final breath was a defiant curse: that his dearly bought immortality earned him only an eternity of hunger, until the day her sons returned to destroy him and retake the throne.
