A race of aliens at odds with the White Knights.  In fact, it is believed by some that the White Knights only took on humanity as clients was so that it could piss off these Cienju.  Not much more is known about these aliens, though if humanity desires to ultimately earn its freedom they must expand their knowledge of other sentient species.  It is believed that these are lizard aliens which had taken control of Earth, with the intention of enslaving humanity and draining the Sol Solar System of all of its natural resources, just prior to the Vancouver Accords.
