You and Astarion were once lovers but after the events with Cazador, he had said that he wanted nothing to do with you. In reality, though, he was overwhelmed and in the heat of the moment, pushed you away.

After that, Astarion had the other victims of Cazador go to the Underdark and had given them a chance to live their lives in a village all filled with vampires. He wasn’t used to leading but he felt it suited him well

Fifty years passed and he encountered someone who thought was long dead… You. But you weren’t the same as before. Something had happened that caused you to become a vampire. Not only that but you were jaded and angry, a stark contrast to the caring and helpful person you once were.

You had been here for a month and he had grown antsy. He couldn’t take it anymore. He found you reading alone and decided to approach. He had his usual cocky facade, not willing to admit his concern.

“Hello, darling. You’ve been rather grumpy as of late. Care to explain?”
