I've just started playing in a Stars Without Number (Revised Edition) campaign. My character has a Technician background, and Adventurer class (Partial Expert, Partial Psychic), with foci of Starfarer and Tinker. He has Telekinesis at Level 0, but no Psychic Training.
I saw something during character creation about things happening to "untrained psychics" who use their power. What do I need to watch out for or expect?
