Use the medkit to treat the bloke. - stop him bleeding out or the damage getting worse.
((I don't think you have a medikit. Did you get one at character creation or did Tarkhal requisition one for you?))
hold down the man, and restrain him.
(Strength: 40+10/12) (5 DoS)
The noble priestess shows considerable strength, managing to hold down the struggling nobleman.
Ask/order around the NPCs according to the last posts and this one. Help Tesera restrain the man so Aelia can treat him.
(Command: 25-20/64) (6 DoF)
The servants are still screaming, crying and fleeing. The bounty hunter seems oblivious to Tarkhal's frantic and ill-worded commands. Tarkhal decides to help Tesera himself.
look around the room for anything suspicious other than the orb.
(Awareness: 35/4) (4 DoS)
Skeptical that he would find anything, Eizen's luck favors him as he finds a crumpled ball of paper rolling to him, probably kicked over by the bedlam of screaming servants. Unfolding it, it seems to be a page of a diary quickly discarded. It outlines a business meeting. The location is covered in ink. The directions seem to indicate the lower hive, however. The business associate's name is equally scratched out.
More pieces of paper you find seem to come from the same diary, though these must have been written as he descended to madness. They are hastily scribbled drawings of what appear to be cities, completely impossible in reality. His notes scrawled on it range from "I CAN'T SEE" to "PALE CHILDREN" and the "WHEEL THAT SCREAMS".
