The Nexus

Information
In Shadowcrawl the player is trapped in an infinite continuum of static dungeons known as the NEXUS. You are randomly placed in one of an infinite number of dungeons that you can find your way back to.

These infinite dungeons are stored and connected across a 10-dimensional co-ordinate system creating an actual hyper-dimensional super-structure.

About
Perhaps the greatest known achievement of the Ancients, the Nexus is an infinite continuum of static dungeons interconnected through a network of portals that transcend time and space. It links together the most sacred sites of the Ancients across every dimension through all of history. Many of these sites can only be accessed through a portal as they are in impossible to reach locations, being underground, in deep space, miles above the earth or far beneath the ocean. Which means they also have no way out, and since it is not known how to exit the Nexus entering the dungeon is a one-way trip.

However legends of untold Ancient technology still lure everything from adventurers to entire armies into the dungeons. Even mindless planet conquering creatures find their way into the Nexus and manage to rebuild their forces once inside.

A surprising amount of information is known about the Nexus despite the fact that no one who has ever entered it has returned. This is because countless individuals have been there in their dreams. These shared recounts have been verified by numerous dreamers who have had similar experiences and sometimes they even gain knowledge from the Ancients that they retain outside the Nexus. All these signs seem to point to the fact that the dreamers' experiences are true and that they really have seen inside the Nexus.
