It’s Falen. Took a class dip to acquire telepathy and a feat called mindsight. It’s sort of an echo-location based on Intelligent creatures. If it has a language, he can pinpoint the creature within 100’. Not unlike blind sense or tremor sense. Psionics are readily identified, as well as extra-planar creatures. One of the other feats he has is a linguistics feat allowing a new language every level. All combined, once he gets good at it (something new like that requires some role playing adjustment), he should be able to tell the party who’s really around them. He can’t call shots, so to speak, but he can identify intelligent creatures by their intelligence, or omission of it (like the young Knight, who probably has mindblank or something similar). Not Professor X, but not bad as an Unseen Seer.
