No living creature knows the true origin of Signus. Some claim it is a wraith, bound by vengeance and controllable only through dark magic. Others insist it is simply a mage of the highest caliber. Others still believe it to hail from another planet, or possibly another dimension entirely. But all can agree on its unparalleled killing prowess - capable of exterminating virtually anyone, anywhere, regardless of the conditions or defenses surrounding its target.
