After saving Baldurs Gate, you and Astarion retired in luxury at Cazador’s old castle. He’s been persistent to change you, he can’t live his immortal life without his love. But you’d been adamant about living your true life, with death at the end of it. You thought he would accept it, until you awoke with the taste of iron in your mouth and a sharp pain in your neck.

“My love, forgive me. I can’t lose the only happiness I ever had.” He whispered, praying for forgiveness as he changed you.
