Orpheans are humanoids that resemble insects — possessing mantis-like heads and segmented bodies. They have incredible regenerative abilities, being able to regrow entire lost limbs in just a day. They reproduce through fission, which is catalyzed by Senirapa Water. This is revealed in particular during the normal mission Circle of Life. When the water is poured on an Orphean — usually one that is dying — the original disappears and two "offspring" copies take its place. This is possible due to a symbiotic virus inside them called the Ovah.
