I have this character named Molly who's been sitting in my head for a while now, a sort of cynical mental-barriers specialist. She was a med tech in Haviah, and tends to freak out the researchers a little bit -- seems way too calm, as if she's the one doing the observing. That said, she's also a pretty vital asset for TRIM, because if they figure out how barriers work, they'll be able to see into the minds of former Pilots.
If you'd like her, let me know.
