The Crimson Sky

A parallel world, existing side-by-side with the human one...the majority of the Crimson Sky-a name which was given to it by the Chasers-is pretty much equal to the 'adjacent' areas of the human world. For example, a city on Earth would have a twin, albeit mostly deserted and eerie, at the same location in the crimson world, and so do mountains, forests, rivers, etc.

The Crimson Sky, is also home to many unknown or undiscovered Youkai, some older than most and some younger than many. The Crimson Sky may also have dimensional traveling properties, pulling people away from their world and into another, but it's a rare thing for some people or Youkai to ever experience.

However, for those who either know the way or are unlucky enough to get there by accident, there's another layer to the Scarlet Realm; the Deeper Shadows, laying a step further into the darkness where even the ever present red moon never dares to touch.
