Corpus mods are artificial organs installed through routine surgical procedures to grant augmented biological capabilities, enhanced physical performance, or specialized physiological functions. The insertion and removal process is remarkably streamlined; an auto-med unit can complete the operation in minutes, and biogel applications reduce recovery to a matter of hours. This ease of exchange has normalized their use across Endless society, where individuals regularly swap mods to suit specific duties or missions much as one might change attire for different occasions.
The practice originated within the Endless Unity well before the Traphon War, though it was not until the Gene-Wars that mass implementation and rapid variant development transformed corpus mods into a ubiquitous feature of civilian life. They are now universally regarded as beneficial instruments for improving personal functionality and charge performance, with social pressure encouraging their acquisition.
Despite their relatively modest individual cost, the sheer scale of the Unity's population creates persistent demand that outpaces supply. This resource tension means corpus mods are not always readily available, a situation exacerbated by the economic disruptions of the Great Schism. Possessing even a single mod signals some degree of wealth or status, while those bearing the maximum number their physiology can accommodate are typically recognized as affluent or influential figures.
Acquisition occurs primarily through biorestoratories—general medical facilities that handle routine procedures for the civilian population. Citizens may purchase mods using state merits, receive them as rewards for distinguished service from factions or influential organizations, or obtain experimental variants from advanced biolaboratories. These specialized facilities occasionally offer unique functionalities unavailable through standard distribution channels, catering to those with sufficient resources or connections to access cutting-edge augmentation.
