Ocularum

From the outside, it seems to many as little more than a loose association of disparate crime lords. This perception is a mistake. The Ocularum is the largest faction, by population, of Beholders in the Zyxx quadrant. The organization is formed by allied organized crime syndicates across the quadrant. As most beholders work in the shadows and behind the scenes as a rule, the organization formed from them is commensurately inscrutable.
Each member cell is its whole unto itself. The organization does not provide governance or aid to members. Rather, the group shares information and loans resources to promote the betterment of beholder interests as a whole. Internally, individuals hate one another and jockey for power and position the way that beholders have always done.
Uniting the membership is a complex set of rules and customs necessary for the cooperation in the face of such seething internal strife. However, these rules can be succinctly summarized: do not murder other beholders; if you have information that can benefit the Ocularum members, you must share it; if you have the option to benefit the Ocularum at no significant cost to yourself, you must take it. Outside of these, the beholders generally expect each other to act in complete self interest.
While the parties responsible for forming the Ocularum are now unknown, there is a popular myth. When Eidolon fell, the beholder race was initially scattered and gradually declined to a nearly barbaric state. Apparently, the Great Mother grew so sick of looking at her demoralized children, she commanded they engage in at least a bare minimum of cooperation so as to lift each other out of the mud.
