The Tenctonese, referred to as Newcomers by some Humans, are a race of bipedal sapient humanoids indigenous to the planet Tencton which are known for their genetic enhancement of certain members of their own species, for the express purpose of creating a subspecies of Tenctonese slaves that are distributed amongst their various colony worlds. A significant group of these slaves ended up on Earth, where they attempted to intermingle with the local Human culture and properly integrate themselves into their adopted home.
