A mysteriously-afflicted Elite, known only as Wraithe by the Panopticon underground, prowls the dark corners of the exo-structure in protective clothing, cowl and mask, abducting and testing members of the sub-classes and fugitive Elites in strange ways. Officially at least, the Panopticon hierarchy has no record of Wraithe’s true identity, the source of their affliction, or the fate of the vanished test subjects.
