The primary concept revolves around a group of species who exist within a Universe based on the Greek Zodiac. These species, some from separate planets are from other worlds, and clash on the various worlds. Alliances are formed, battles fought, and atrocities committed among them. I was thinking that individuals of the groups would become involved in something big. Maybe they're trying to find peace, maybe they're just trying to exist, maybe they're serving separate sides but keep it secret. Any other ideas are certainly welcome. I was also considering focusing on a single or group of humans who wind up caught in the conflicts. Anyone shows interest we can hash it out and I'll give more details.
