You are very valuable or very dangerous and THEY will come after you. Who are THEY? The Symmetricists are a small but powerful elite that emerged on Penumbra. Wary that unscrupulous Uniques would take advantage of the Reciprocity Effect and manipulate events in one reality to gain power or wealth in another, the Symmetricists created The Symmetrical Guard. They are dedicated to studying and maintaining the symmetry and separation of alternate realities.
But the Symmetrical Guard has been subverted by shadowy forces and now tracks down Uniques to recruit or, if they resist, ELIMINATE.
