Eternal Father

Seat of the NeverbornSomewhere in the Unknown Regions
No one wants to die, but it is near to impossible to escape such inevitability.
Medicine has prolonged life far beyond what was considered the average lifespan centuries ago while cybernetics could halt the aging process in specific areas of the body, but ultimately there was no way to escape that grim eventuality.
The Sith had long been fascinated, borderline obsessed, with the prospect of prolonging one's life indefinitely so that their reign could continue without end over many eons. Some resorted to using their powers to siphon the vitality of others to repair their body and reverse the aging process, but they soon became addicted to their hunger and ended up consuming themselves. Others stored their consciousness in their holograms or other items of power, waiting for the day some unsuspecting tomb raider would stumble across their burial mound and be possessed by an echo of their long eroded power.
Others resolved to using both science and magic to achieve immortality, fashioning clone bodies to transfer their essence into once their current body had been spent. It was this method that the Dark Lord Carnifex had resorted to once he had discovered a means for his consciousness to return from the blasted realms of Chaos. Dozens of genetically identical clones were housed in a facility onboard a micro-planet hurtling through the vastness of the Unknown Regions, its location known only to Carnifex at any given time.
He often didn't visit the Seat of the Neverborn for reasons other than his own rebirth, but he had acquired some interesting genetic material that, after many hours of experimentation and analysis, would improve upon the design of his body in every clone that was created here on out.
