From the introduction:
The PINION Role Playing Engine is the mechanism on which diverse worlds, realms, characters, creatures, events, and adventures can be created, integrated and operated seamlessly. Designed as a comprehensive multi-genre system, PINION is ready to soup-up any game system or milieu.
The PINION RPG can be as rules-light as you like. The basic cores of Character Creation and Task Mechanics are simple and easy-to-grasp. Modifiers and complexity can be heaped on as desired.
