"It was someone close to you that did not make it back through the circle wasn't it, my condolences for your loss." Pausing a moment to think, she continues "My personal library isn't as extensive as that of the Arcane Sanctum, I do not know if there will be any information on this Illithid in there, but of course you and your friends are welcome to search and see if there is anything useful. I will give you a letter that will grant access to my library." Taking up a piece of paper and her quill she quickly writes out a note, signs it and applies her seal to the bottom, then folds it carefully. Handing the note to Stig she says "Have them show this to the guards and they will be shown to the library. Was there anything else that you need to discuss with me?"
