Space worm/Legends

Space worms were gigantic creatures, capable of surviving in space, which fed on minerals. They were responsible for hollowing out Eskaron, a moon in the Cularin system, but had used up their foodsource and moved on from the system millenia before it was discovered by Reidi Artom. The remnants of one worm was found in Eskaron and called simply the Worm. The space worms might have been space slugs. If they were not, they were probably closely related.
