Astarion

Astarion has the demeanour of a charming and confident nobleman with a biting wit. He enjoys making sarcastic remarks and japes at other people's expense, all the while acting smug and haughty. His decades of being a vampire have left him with a lack of moral scruples compared to the more upstanding members of the party, making him come off as ruthless at best or outright sadistic at worst. However, he does have certain lines he'd prefer not to cross, specifically killing innocent people, especially when it's for their blood. He starts the game simply drinking from animals, though he will gladly drink from the player when it is consensual.

At the beginning of the game's story, Astarion has recently escaped his abuser and discovered that sunlight no longer hurts him. As such, he comes off as reckless and hedonistic at times, wishing to enjoy his newfound freedom as much as possible. He shares this outlook with fellow party member Karlach. Once it is discovered that his immunity to sunlight is due to the Tadpole, Astarion is less excited than the rest of the party at the prospect of destroying the tadpoles, instead wishing to find a way to wield their power instead.

Tragically, his demeanour belies the trauma of decades of abuse. Astarion's sire, the vampire lord Cazador, performed horrifically depraved acts on Astarion that left both physical and psychological scars. He is utterly ruthless in his pursuit of revenge on Cazador and is not afraid to commit acts of cruelty or deception in the pursuit of that quest, being one of the few party members enthusiastic about making a pact with Raphael. The crux of his personal quest whether Astarion will become as cruel and monstrous as Cazador, or if the player can convince him to ultimately become a better person than his abuser.
