d20 Future: CODEX GALACTICA
The Ancients known as the Prometheans or “Seeders” as they are sometimes called were a humanoid species credited with the evolution of humanoid life throughout much of the galaxy. Very little is known about these beings except that they were an ancient species of powerfully built humanoids that stood nearly 2.5 meters tall. Only a few Promethean ruins have been discovered, one of which contained remains of some members of the species. What is known is that they were a space-faring species that studied heavily in genetic manipulation. They experimented with their own genetic code, which shares similarities with many other species from humans, to vulcans, to even “animalistic” species like the klingons and Caitians, and even much of the mundane animal life on many planets leading some researchers to suggest that they also experimented with blending their genetics with that of animals as well. This theory of “Promethean Seeding” (also called the “Unified Theory of Evolution”) is still widely discredited, but thanks to research into the extremely adaptable Promethean DNA structure it has gained momentum and even acceptance in the scientific community.
Most Promethean sites are on interdicted planets. It appears that the Prometheans weren’t solely concerned with the creation of intelligent, even benevolent, life, but also created horrors as well. It isn’t certain, but the presence of the dreaded Xenomorphs (commonly referred as the Grendelspawn) on several of the planets that hold Promethean ruins seems to suggest they were behind the creation of these terrors.
Much like the Protheans, Prometheans have become the focus of religious cults. While none of their “Seeder Cults” match the size of The Cult of the Prometheans, they can be found in more systems. Few of these cults are connected to each other, and most have vastly different focuses of worship. Most are benign, but some of the cults have been classified as dangerous terrorist groups thanks to their desire to capture and study Xenomorphs in order to “unleash the righteous fury of the Creators upon the sinful galaxy.”
