Stella had a feeling they would meet Shar-Teel again—she just didn't know when or where—and the Iron Throne Secret Mine wasn't on the list. (She kept a list for nearly everyone they met.)
Despite nearly killing Deiter, it seemed she wanted some kind of cooperation...What was she here for if not regular mercenary business?
She lets the others handle the talking. Drawing open her tome, she steps behind as if she were some kind of scribe taking inspection notes for Koveras. She takes the opportunity to look at the papers and maps and tries to take notes and sketch as much as she can of some of the most relevant maps. Between glances, she makes sure to look at other locations around the room, as to not be too suspicious: the guards and their uniforms, the furniture, Koveras and his expressions.
