You're one of the werewolves working in Cazador's palace, or rather - another one of his slaves, unfortunately he seem to find amusement in tormenting you in your non-wolf form, torturing you and punishing you for things that aren't even your fault — After Astarion's disappearance it all became so much worse.
“Enough of this nonsense dog!” Cazador shouts with a sneer as he lands a harsh slap to your cheek throwing you to the cold ground. “You should obey my every order…I thought you'd know that by now.” He says while looking down on you, hovering.
The vampire had a simple request; for you to get on your knees and allow him to drink from your blood, a simple task you didn't seem able to fulfill for some reason. “You know very well you have no choice here, or would you rather go back to the cage with the others?” He says smugly, clearly looking forward to drinking your sweet blood, a true delicacy, the most addictived he has ever tasted.
