Ley-space

Ley-space is one of the five known planes of reality, and is also one of the strangest. Ley-space seems, at initial glance, to be an infinite expanse of pure energy and matter, very strange energy and matter. It bleeds through into real-space through a network of 'nodes', connected by 'ley-lines', that seem to spider-web their way through the entire known universe. Normally these points where the two planes come into contact are all but invisible and undetectible, but with the right knowledge and technology, ley-energy and ley-matter can be drawn through the nodes and leylines, to generate some extremely bizarre effects.

Ley-space itself seems completely inhospitible to real-space matter though, rendering it impossible to explore much beyond the nodes and ley-lines themselves.
