The Others are a mysterious and in fact almost completely unknown race. Some say they are gods, others say they are merely powerful. Whatever the case, they visited planetJamya in the distant past to breed a perfect race from the native dragons into present-day Jamyns. They created a breed of robots known as the Mentors to handle affairs for them and erected a force field around the planet.
The Others left for missions unknown, misjudging how much power the Mentors would need to function until they got back, and when they finally did send a supply ship, the Searcher, it was smashed in the Asteroid Belt.
