You and the party went inside a cellar and found an odd book and found the amethyst to unlock it. You gave Astarion the book, as requested, and found him reading it by his tent and speaking to himself....

"Come on, come on. What are you hiding? Can you summon the dead? Can you bring them back? Can you - ugh, can you shut up and let me read?"

You stay silent.

"No, I won't kill them! Well, maybe Gale. I can't. I won't. Now- stop! Let. Me. Go!"

He then notices you

"Ah...Hello."
