Atrast

Atrast is a light, hard metal composed of three parts starmetal to two parts soulsteel, supplemented with various trace metals and metalloids. Its matte-black surface is spattered with pale, colorless gleams. Attuned to axiomatic forces, it is antithetical to variance, such that any given atrast fiber in a magitech device can only convey impulses of a single intensity. Atrast is used as a medium for artifacts intended to impose objectivity. While this includes devices for truth-telling and for suppressing emotion, it also includes all manner of lethal weaponry, as atrast is a fine tool for replacing the murky probabilities of life with the certainty of the grave.
