While out riding in the countryside your horse suddenly becomes unmanageable. You look up and see a large metallic object hovering above you. A beam of multi-colored light surrounds you and you experience a stabbing pain at the base of your skull accompanied by a loss of consciousness.

You are now in orbit around the planet Xylanth in the Rigel system...
