The Transadapts
These creatures were genetically engineered in secret using the alien abduction coverups during the eighties and nineties. Small in stature, they were specifically designed to live in the environment on Mars, the colder temperatures, the lower oxygen and lesser gravity.
They are looking for a new home as they are now sterile. The leader of the Transadapts is a tiny man who is proportionately perfect for his size. He is the offspring of a human and a Transadapt woman.
The Transadapts were sterilized by the humans on Mars but ended up wiping out the humans. In a long war. They are trying to find a way to reverse the sterilization in order to save their race.
Sindri wanted Brigid as his mate and he literally milked Grant and Kane for their sperm in a desperate attempt to save the now dying race.
Physcially they stood no more than four feet in height. The arms were disproportionately long in comparison to their legs. The hands of the transadapts were splayed, squared tipped with bevel edged nails. The body was low and powerful.
The head had low sloping brows covered by hair, and the complexion was very dark, but the features were not like a blacks. The features were blunt and they tended to appear to be quite stupid.
The feet were very long and had inch thick calloused. Each foot had nine long under-curving toes. The tenth was very long and worked like an opposable thumb.
