Vampire the Masquerade
Isaac Doom (Sabbat: CAPTURED)
Adam Serrano was his Childer and Isaac took it personally when Adam fled the Sabbat to join the Camarilla. Isaac wanted revenge for the betrayal.
In the process of killing him Isaac mentioned “that a bomb would be detonated in the city by the Sabbat that could kill millions. All your precious humans will die. I just wanted to kill you myself before the bomb goes off.”
He is currently bound in Mat’s basement.
