The RACelestials (sometimes spelled RACCelestials) are cosmic beings of mysterious purpose who watch over Usenet and the rec.arts.comics.* hierarchy. They seem to watch over many basic functions of the Usenetverse, including the creation of new newsgroups and the judgment of existing ones. Their actions, while stabilizing on a cosmic scale, often cause chaos for mortals.
In an alternate universe visited by Particle Man, the RACelestials judged the LNH a waste of bandwidth and devastated their world, and most of the Legion died in battle against them.
They created the Walkers for their own inscrutable goals.
