Rift-Way

A one way capillary stream towards the beginning of existence offering a method of transport through space and time.

it is seemingly nonsensical in a Euclidean realm of thought,

though those (un)lucky enough to be caught in the white-waters of a rift-way have access to a super-positional system of transport existing simultaneously across all of space,

until their position is collapsed via exiting the stream via it's walls.

Many races have travelled the Rift-ways in hopes of mapping them but with middling degrees of success.
