Strahd vs. The Gentlemen Bastards
Killed by Kylar in Chapter 2.
Doru was the son of Father Donovich. A little more than a year ago, Doru, and several other villagers stormed Castle Ravenloft in revolt, having been lured there by a wizard in black robes who had come to Barovia from the mists.
By all accounts, the wizard died at Strahd’s hand, and so did Doru, who returned to his father as a vampire spawn.
Doru had not been fed since he was imprisoned, and he cried out to his father at all hours.
Winston convinced Father Donavich to allow the Gentlemen Bastards to experiment with Doru, to learn all they could about the weaknesses of vampires. Father Donavich very reluctantly agreed, as long as no harm would come to Doru. This plan quickly fell apart and disaster ensued. Doru was destroyed by Kylar in the struggle.
