I have a question for the experts, not sure if this is the right place to ask it. My question is (hopefully) wrapped in a spoiler tag here:

In my current play through, I opted to help Shadowheart achieve Dark Justiciar status, and lead the Sharran church. This of course required the death of the Nightsong. Now, I've gotten to Act 3 and Sorcerous Sundries, and confronted Lorroakan and told him she's dead. He had a fit, and then the dialog ends. No attack, no questions, nothing else. Any time I speak to him again, he just whines and "hangs up on me" smile

So my spoiler question is, with Nightsong dead, how do I get into the Sorcerous Vaults? Simply attack the man for no real reason? That seems a bit rude... though I have no problems robbing him blind. Does he have to die for me to raid his vaults?

Thank you!
