Magitech is sophisticated equipment, amplifying one's VooDoo powers; the Stellar Empire has known it for so long that this technology can be found in endless applications. This knowledge is essential for our development of said equipment.
Contrary to popular opinion, the mage is rarely the main source of power; her relevant mental skills (V.Power and V.Skill, but sometimes also Bravery and others) rather, allow using an instrument's power to lesser or greater extent, and everyone has a V.Power rating, even if it's hidden (not evaluated).
