From the designer's webpage:
The Year is 2085 and long range teleportation technology has made faster than light travel possible, In an attempt to find habitable planets earth’s governments send out probes into deep space.They found something. . .

Welcome to the Artifact, a world foreign to our own Earth in many ways. A world that was manufactured for some as yet unknown purpose. Here you will encounter hostile aliens like the Kelrath and the Chezbah, and those that will seek your aid, like the Scimrahn. Races that appear human but are different from us in many ways. Then there are those that hide in the shadows, like the giant Tanroc Fredar, and the thing called Loc, revered as a god by some, despised as a demon by others.

A small group of explorers from earth are the first to venture into this vast world. Some looking for a better life, some for the adventure, and some looking to strike it rich in the amazing resources that are available.

The Artifact is a Role Playing Game that each player will take part in a unfolding world. As members, they will have the opportunity to add to and influence the world around them.
