A faction with an interesting theme and a nice contribution to FIST’s antagonists. You can use this group as a possible client, enemy or meddling third-party in any mission.
I might drop the telekinetic mercs. Messing with senses and the mind is this group’s raison d'être and if they were exclusive on those techniques it would be more thematic. (I assume the Oasis agents are masters of motivational speaking.)
By the way, how would one pronounce Sombroek?
