"When I was fourteen, my parents were killed in a gnoll raid, and rather than finding honest work I turned to theft to survive. I started small, food and spare change, but over time I stopped trying to take just what I needed to survive and started to take whatever I thought I could get away with."
She looks down. "Eventually the raids got bad enough that a holy order that was passing through came to help. But all I could think about when I saw them was how much their gear would go for on the black market. I picked out the nicest helmet and lifted it while Ser Acemi was sleeping."
It's fortunate how being a paladin makes it impossible to be afraid of how telling this story will go. "I'd been planning to sell it straight away, but some part of me still knew that what I'd done was wrong, and every time I tried to find a buyer I felt so guilty I couldn't bring myself to sell it. But I couldn't work up the courage to give it back, either. Before I'd made up my mind, there was another raid, and — one of the gnolls caught her straight on the forehead. She was dead in an instant. There was a funeral for her afterwards, and I took the helmet and tried to crawl onto the pyre to die with her."
She meets Blai's eyes again. "...At that point the rest of the order pulled me out of the fire and told me that was a terrible way to make up for what I'd done, but that if I was willing to follow their rules they'd be willing to let me train with them so one day I'd be strong enough to do the work she could have done if she'd lived. And when I'd been doing that for long enough, the Goddess saw that I really meant it, and that I could be trusted to stick to it, and chose me as a paladin. So I guess what I'm saying is — you're not the only one here with Evil in their past, but what matters to the Goddess is what you do in the future."
