Spriggan

An advanced society that once governed the Earth many years ago and was recognized for its cutting-edge technology was ultimately wiped out by its misuse. In order to warn future generations that their creations should be destroyed if they could not be put to good use, they placed notes for them on indestructible message plates that were written in ancient Hebrew. Armed private groups, national armies, and paramilitary organizations all started looking covertly for these "strange objects" to employ against their foes and for their own good. With the help of their highly skilled secret agents known as Spriggans, the ARCAM Corporation and their military branch, the ARCAM Private Army, can prevent these forces from destroying themselves (or Strikers).
