Two hundred years ago the walled kingdom of Olvion was attacked by a horde of brutal sub-humans bent on the destruction of mankind. Just when all appeared to be lost a mysterious giant of a man appeared and inspired the people to victory. No one knows what became of him but the citizens of Olvion named this mysterious man "The Legend".

Jack Taggart awakens from a surgical procedure naked and alone in a strange and exotic world. Alone, hungry and doubting his own sanity he is befriended by a wonderful little animal that communicates with him via telepathically projected images and emotions. Taggart names his new friend "Tinker" and she becomes his guide in the strange new world. But Tinker is on a mission and she recruits Taggart to aid in that task. The two undertake a journey which crosses the paths of a beautiful woman, a king and the many noble male and female warriors of Olvion.

When a second invasion of the "Grey Horde" begins Taggart, aided by Tinker, uses his unusual size and strength to aid the human defenders in halting the advance of the murderous beasts. As Taggart's combat successes mount many in the kingdom of Olvion proclaim him to be "The Legend", returned as predicted in the ancient writings and stories. Is he? Or does Jack Taggart have another role to play?
