This is a one-page freeform magic system for the Cepheus Engine and similar OGL 2D6 rulesets. While extremely short, these rules provide surprising complexity. This is a mana point-based system similar to the Classic/Mongoose Traveller Psionic rules. There are no specific spells, but rather six spell categories varying in skill throw difficulty and mana cost. The difficulty (total skill throw modifier) of casting a spell depends on a wide variety of factors, allowing for interesting situations - for example, using somatic and vocal components (ala D&D) provide positive modifiers.
The system is heavily Referee (Game Master) dependent. The spell category and qadditional modifiers are up to Referee judgement, with very general guidelines. This is very Old School in flavor.
I would have liked to see a slightly loonger product including more concrete examples of spells, but the current rules are definitely solid and recommended.
