Magic Rules for Interlock Unlimited

From the introduction:

Magic can be defined in many different ways. To some Magic is the life-force of the very universe; to others it is merely parlor tricks and hokum.

Interlock Unlimited does not attempt to explain where magic comes from, we feel that is best left to the Game Masters and players, who are crafting their own worlds, or using this system to play in their favorite settings. Instead, our goal is to provide simple rules for how it works in game terms.
