Forgotten Tapestry

The Forgotten Tapestry is a hidden realm containing the ruins of all previous universes, and is the foundation upon which the current cosmos is built upon. Separated from the Physical Realms by the Void, the Forgotten Tapestry contains all that once was. In it one can find the tattered remains of dead and forgotten universes.

Overview
The Forgotten Tapestry can be likened to the foundation of the current cosmos. It sits below (or more accurately all around) all known planes, realms, and worlds. As the cosmos expands it pushes the Forgotten Tapestry ever further out. However this comes with the risk of the Forgotten Tapestry piercing or intersecting with the cosmos. This has happened on numerous occasions, with the most significant event being the invasion of the Physical Realms by demons.

Travel
Traveling to the Forgotten Tapestry is difficult even for the most skilled of magic users.
