The Forest of Surreality is an immense forest within the fifth dimension. It is so large that physical travel into or out of its heart is impractical, since it would take nearly infinte time.

The forest is home to many native denizens, including Number Red.

The forest is nominally claimed by Yah, who attempts to exert his authority through underlings, such as Thaymus. During the Battle of Sandy Creek, sections of the forest were burnt by the forces of Yah.
