A leader and scientist, Raiker fought on behalf of the Er'ther army against the Aetherians during the Aeth'er Wars. At some point, his personality was projected into a computer in Radisrol, as he aids the protagonists in Tales of Destiny, using the scientist Reynes's help to devise a plan that will allow the group to disable Dycroft's defense mechanism, restore the Swordian Igtenos, and infiltrate the Aethersphere for the sake of defeating Hugo Gilchrist, and ultimately, Kronos.
