Crossover A MIDDLE-AGED MAN IS CHOSEN BY THE COSMIC FORGE AND FOUND HIMSELF ON RIFTS EARTH (RIFTS)

The Cosmic Forge, patron, and creator of the Cosmo-Knights.
The Megaverse is in dire need of Champions, so she chooses another one.
This one is an author with meta-knowledge of the entire setting. Maybe he should be as helpful as those she already blessed with her imitation of the Celestial Forge?
Time will tell.
