THREE WORLDS ... JUST ONE ADVENTURE It starts quiet harmless: A couple of friends meet for a GURPS-RPG-session. They want to get into an exiting adventure in the phantastic world of a new gamemaster. And so they will - though different then they expected! Suddenly the gamers get in the world of endless opportunities ... ALL BYY THEMSELVES ... up into a game without frontiers. First of all the gamers have to get through the hyborian world of CONAN, the barbarian, Where they have to fulfill an ancient prophecy. To find a magical jewel of might just before the enemy would do. Only if the adventurers restrain their antagonist Deloth from setting the Mosaic Of Might together, they could get back to their origin wolrld. But getting home gets quiet heavier then expected. Still on the search for further pieces of the Mosaic Of Might the adventurers have to get through the merciless future-world of CYBERPUNK. In the year 2020 they have to face the menace of High-Tech-Cyberspace and Low-Life-Urban-Jungle. After that the story goes on in the world of classic horror. With demons and vampires. In a world of the 19th century, which Deloth has almost totally under his reign of terror. Only if the gamers are up to the challenges of all three worlds, they could help to influence the fate of all spheres and boost the power of light. This is the first German original GURPS-adventure-module. The adventure "Meister der Sphären" (Lord of the spheres) shows a one-of-a-kind introduction of the possibilities and themes of the the GURPS-universal-rpg. It demonstrates one of the big potencies of GURPS - the easy way of switching from one rpg-genre into another. It's a fascinating turn from our present world to CONAN's fantasy world, high-tech-cyberpunk of the future, the gaslight-horror of the Victorian age, and back again. There's not better way to learn about the multi-generic possibilities of GURPS. (translated from the back-cover of "Meister der Sphären")
