Class fantasy
Thought moves first. Everything else is consequence.
Psions turn thought into force. Their power needs no reagent, no prayer and no gesture, which makes it both the hardest discipline to learn and the hardest to prove. They strike at range, shield themselves in kinetic pressure, and win by taking an enemy apart from the inside out.
Psions open with force, wrap themselves in a kinetic barrier, and dismantle a target between the ears while keeping distance honest.
A discipline nobody can see leaves witnesses uncertain what they watched. Credibility comes slowly, and Threat Index arrives the moment someone works out what happened.
