The Thousand Worlds contains modern-day Earth, and is itself contained within the Burl. The other significant portion of the Burl is the Dreaming, a liminal space and time that surrounds the Thousand Worlds and (to those able to travel within the Dreaming) connects it to the rest of the Yggdraverse.

Just as there are very few who can traverse outside of modern-day Earth into the Thousand Worlds, there are also very few who can traverse from the Thousand Worlds into the Dreaming and from there into the Yggdraverse. Travelers who die in the Dreaming will also die in the “waking world”, but souls thus lost in the Dreaming will stay as they are for as long as someone remembers them.

As is normal for liminal space/time, the Dreaming can take many forms depending on who is traveling – though some posit that the Dreaming is simply vast enough to contain all those possibilities and it’s simply a matter of where you enter. One more or less permanent location within the Dreaming is the Valley of the People of the Dragon. The Valley is home to Jake, also known as the Old Wolf, who keeps the prophecies about demons.

Prophecy of the Demon of Darkness – as told to Nicole Matthews during one of the times when she in her dreams usurped the body of Penny Layne, who is Jake’s beloved and was one of Nicole’s past lives.
