Liam: Thanks for mentioning the ex-marine remnant from "Jump Madness" (I think that's what the module was called.) I just loved that guy. I know he was supposed to be a anti-Imperial propaganda but the idea of that guy mentally re-fighting a 5FW ground action and calling nosy players "stinkin' Zho sympathizers" gave me the nostalgic warm fuzzies. I'd like to use him as a recurring NPC. What the heck was his name?
I like the Lovecraftian "Things Man Was Not Meant to Know" tie-in with j-space. This might make for an excuse to dust off my copy of Dark Conspiracy's "Dark Races, Vol. I" for all those dimensional horrors. Maybe j-space could be inhabited by creatures that can only interact with us if we directly observe them: or similarly, perhaps trying to observe jumpspace attracts their attention. Imperial society might have banned private research into the phenomenon because surviving contact with it can cause the spontaneous manifestation of psionic abilities. Bereft of the discipline instilled by proper psionic training, AND traumatized by the experience itself, a deranged but charismatic figure could emerge who claims to represent the Outsiders (as evidenced by his "gifts.") There's a good basis for a cult. What with the meritocratic, worldly cynicsm of the RC, a cult like that could fill the spiritual void of the disenfranchised, too poor or lacking in talent to leap to the stars.
