Perranomia

One of the weirder realms are Perranomania. It contains nothing but oxygen and helium. Perranomania is a blank slate in case somethine goes terribly wrong in any other realms. In that case, all of the history and memory of the fallen realm will be transported to Perranomania. This realm is quite alot like how Veladom used to look, before it replaced Cetadom.
