The ancient mechanical entity known as Zildrog has always operated from behind the scenes. Unlike the other "machine gods" of Iokath, Zildrog permanently functions in two forms.
The first is a central computer that specializes in the transfer of life energies. Given this device's presence on Nathema, it is likely that Zildrog was a key element of the original ritual Tenebrae used to empower himself at the cost of all life on the planet. Beyond that first atrocity, however, Zildrog's central mind appears to have played no role in Tenebrae's dual life as Vitiate and Valkorion, and slumbered in stasis mode until Vinn Atrius discovered it many years later.
The second of Zildrog's forms is the ancient warship known as the Gravestone. Though it can be operated by an organic crew when required, the vessel's Dark Heart functions as a remote command core that allows Zildrog to control the ship as an extension of itself.
Ancient Zakuulan myths often confuse or conflate Zildrog and Izax, likely because both entities are aerial platforms employing omnicannon technology. Given the many differences in their construction and operation, it seems likely that they were actually built entirely separately--perhaps even as rival projects carried out in Iokath's endless pursuit of better and deadlier weapons.
