Effinites

The Effinites were a secretive group of cloners who resided on Vesta in the Asteroid Belt. Their order was comprised entirely of clones of their original founders. The Effinites often did not communicate with outsiders and rather focused on creating a subterranean paradise within Vesta. Because of their ability to create exact copies of memories, personality, and other mental traits as well physical bodies, Effinites are considered to have found the secret of ancestral memory, with rumors circulating that they had even been able to unlock memories from before their predecessors were cloners and of ancient Earth.
Due to their advanced scientific knowledge, Effinites were highly sought after by many nations throughout the Solar System, and many ambassadors came to them to ask for their secrets, or, failing that, an alliance. They were very selective with who they spoke to and never shared their secrets, but could give gifts to those they deemed worthy of their genius. Effinites were considered to be very unusual, conceited, and pretentious to outsiders. However, their intelligence was respected by all the nations of the Solar System and this was reflected in their demeanor when they attempted to ask the Effinites for a favor.
