"A dimension full of gateways to every planet in the universe arranged by what solar system it's in, what galaxy it's in, and what galaxy cluster it's in written in a language that translates itself to any language the being is native to but exploring it would be like trying to solve a endless labyrinth and can only be accessed via a Singularity Drive or to the center of the Bermuda Triangle.
Those dudes in the Gateway Dimension are dead if they don't have a Singularity Drive because a Singularity Drive can be used to access the Gateway Dimension and also used to create shortcuts to the desired Gateway for a more easier way rather than exploring it
