Nebulos

The Nebulos is a helfstep between Valearia and Earth. It is like the Prison in the fact that it cannot be opened from the outside.

Nature
Like other halfsteps, the Nebulos is expansive, stretching out for many miles in every direction. Unlike Dreamscape, there are no currently known borders, but it is assumed that there is an end.

It appears as a red expanse with black clouds. The halfstep is filled with large chunks of stone and earth, creating large floating "islands" or "continents." These can range in size from a few meters in diametre to over a mile.

Devri, stabalizing a Silver Thread using Power Stones, used a far corner of Nebulos as a base for his war efforts.

History
The Nebulos was used on many occasions to trap things that were undefeatable. Several notable beings were rapped there, including Atma, Valos, and the Three, as well as many of Jarnik.
