A space lattice, in the three dimensions, is any of 14 possible geometric arrangements of points, at which, at the very least, the components of a crystal may form…this is why crystal propulsion is so clean and so very efficient, to name but one effect.
A space lattice, in the realm of sorcery, is all of 14 possible and impossible arrangements in the geotic fields, and include the laws of necromancy and the location of high magnetic energy points of sacred sites.
A space lattice, in the fourth dimension and those beyond, is the 14 impossible arrangements of will and thought, where the continuum is temporal and spacial simultaneously, at which point space-time unfolds and space-folds are beyond measurable time.
In this lattice lies all possibility, where not even imagination has ever been. This is Reaume, and Ariann…and, yes, lest you forget, Lethe. Watch yourself, friend.
