Program Canaan is the general term for a group of surveillance systems that searches for people with the special "factors" necessary to become a Testament, suitable for a Vessel of Anima. Its basic outline was devised by Vector Industries for Vector's CEO, Wilhelm. During the dawn of Realian development, it was installed in a very small number of units and integrated into their basic brain-stem systems. Regardless of their own will, Realians who have been installed with this program have the role of judging suitable people and helping them awaken their abilities.
