DIMENSION DOOR
It has been discovered that a transcendental traveler, upon magically
entering the
Ethereal Plane of Atrii,
can easily return to the real world via
magic curtains specially designed to provide a one-way trip. These
Dimension Doors are seen as closed curtains hanging suspended in midair.
It is known that the enchantress
Y'Gael had at least four portals that were dimension doors (or similar to them) in her
Gurth City,
Mizniaport,
Accardi-by-the-Sea, and
Festeron shops.
