What is the main setting in the novel, Fear the Fantastic?

The novel is set in Everworld, "A universe within or beside or next door to the real universe. Totally different rules." Magic works in Everworld, and Dragons with huge bodies and wings fly about like birds.

Everworld was created by the old gods of earth, who for some reason grew tired of living on earth. They created Everworld, apparently in a universe different from that of earth, and moved there.
