Well that's a second group which is at least friendly to us, and claims to follow the guild leader. They must be separate because they want to get rough with the other groups (unlike the first group).

The three remaining groups, is there a location that is less than 30 feet from all three? I'd like to angle our party there so I can attract for Fade on these tougher diplomatic sells, without walking up with him, or obviously leaving our group to do so (psionics with signs suppressed is much more subtle than casting, but walking up first sort of ruins that).
