Summary

 * Epic Science Fiction
 * In the 22nd century, humanity has ventured to the stars. Yet alien races, fractious colonies, contending governments and aberrant mutations all vie for supremacy amid the wonders of this new age. At the center of the conflict stands a new breed of humans — men and women with psychic powers — whose actions will determine humanity’s ultimate fate.
 * A Universe of Adventure
 * Trinity is a game of epic science fiction. This campaign setting is fully compatible with the d20 System, with source material on a universe where aliens and the powers of the mind are real — plus new classes, feats and powers so that you can take on the role of a courageous space explorer or a psychic-powered psion.
 * Sword & Sorcery books are published under the Open Game License and are 100% compatible with v.3.5 rules and the d20 System.
 * This is the core rulebook for playing Trinity, the final part of the larger Trinity Universe setting. In this book, you play psions, each from a different Psi Order. Sixty years ago, the formerly-human mutated Aberrants, with powers to reshape the world around them, were exiled from Earth following a devastating war... but now they want it back. The Æon Trinity unifies the disparate Psi Orders to drive the Aberrants away for good.

Background Information
Differences between this printing and the Storyteller edition are moderate. Unlike the Storyteller edition, this book is set after the return of the Upeo wa Macho (the teleporters), and therefore are presented alongside the other Psi Orders as a playable group. Additionally, most references to the word "psionic," including in organizations' names (like the original Ministry of Psionic Affairs) has been replaced with the word "noetic." Finally, some locations are given more accurate names, such as Nippon becoming Nihon.
