Kharas returns under the hole. He seems now used to teh presence of teh iron guardians watching him. "Can you pull me up a second." tells Kharas. After being on the top, he explains the situation, telling what he has found, showing the mace he has taken and explaining what seems like a lock. "I havn't search completly the place, but if they have put so much effort to lock that thing there, warding him and protecting it with iron guardians, I would be surprise to find the three keys. It is not too complexe lock, but I won't be able to do it alone. I'll need some help... Mordin, I think you know a few thinsg about locks and traps? If you could help me... the only problem with that is the two dogs. The boo seems to make his effect, but what about the one who doesn't hold the book... Ok, here what I suggest, I finish to search that place, maybe I'll have a clue about where are those keys. If I find nothing, we will figure a way around those iron guardians for Mordin and both of us will try to open that thing. What do you think of that?"
