An example of an interdimensional portal (terrestrial version).

An example of an interdimensional portal; this one in is real space.
An Interdimensional Portal is a portal that acts as a wormhole, creating a gateway between two locations in space-time. It is is a speculative structure linking disparate points in spacetime.
An Interdimensional Portal is visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Due to their appearance, however, they are often mistaken for black holes by most spacecraft.
Theoretically, an Interdimensional Portal might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
Mobius and Savoth are two planets that can be accessed through interdimensional portals.
