The Genotypes of the Zenith project started by the Megalith Corporation eventually expand to become an entire caste system of genetically engineered and artificially created humans.
Cohort Genesis
The first generation created in secret by the Megalith Corporation. The original genetic experiments produced a batch of children with unusual characteristics but who were more or less otherwise normal humans. This involved basic gene therapy treatments, strand purification and subject conditioning of natural humans.
Adam
The original artificially birthed human, Adam, genetically engineered to be superior in every way. In practice this led to far superior physique and intelligence at the expense of empathy. The first problem was revealed that Adams did not get along and ended up competing for power.
Eve
The second genetically engineered human, engineered to be more submissive and controllable. Eve still had above average physique and intelligence, but was exceptionally empathetic.
Samson
The first attempt at splicing animal DNA, this variant of Adam was incredibly strong physically, but stupid and psychopathic.
Solomon
The first attempt at enlarged brain size, this variant of Adam was extraordinarily smart, but weak and antisocial.
Sarah
This was a highly physically attractive variant of Eve.
Mary
This was a highly intellectually attractive variant of Eve.
Cohort Exodus
The second generation of genetically enhanced naturally born humans, these had more controls implemented and were more socially compatible. These variants were developed just before the exodus from Earth forced by the defeat of the Consortium. At this point the Megalith Corporation changed strategies and using the research completed from the previous studies took the results public, producing the first batch of stable artificial humans. The previous cohorts were abandoned, and the first true generation according to Zenith Imperial history began. A balanced trade-off theory was ternary and incorporated six genotypes. The three points of the triangle are focused on physique, intelligence, and empathy respectively. The three middle grounds balance between two of these characteristics.
Lords
Originating from the genes of founder and CEO, Marcus Dusk, they are genetically engineered to be a balance of physique and intelligence and bred to command the forces of the Imperium. Due to a lack of empathy however, they are known to be rather ruthless bordering on psychopathy, which does much to explain the aggressive behaviour of the Imperium.
Nymphs
Originating from the genes of model Pamela Crawford, they are genetically engineered to be a balance between physique and empathy and tend to be very attractive. They are not very intelligent however.
Giants
They originate from the genes of a mercenary security contractor named Arnold Bolt. By combining animal DNA it is possible to focus on physique and engineer unhuman toughness and strength. Overtime they developed into elite shock troops, standing seven feet tall, with massive musculature, and abnormally thick skin. They tend to be dumb and psychopathic.
Fairies
They originate from the genes of a secretary and house maid named Miki Hitomi. These cute creatures focus on empathy through utilizing herd animal DNA to acquire more docile and submissive characteristics. Generally considered a pet caste, they serve as willing servants. The original Eves were much milder more balanced versions of these.
Wizards
Originating from the genes of CTO and Noble Prize winning physicist Professor Steven Einstein they are a uniquely designed series of humanoids whose cranial capacity was stretched to the limits of physics and biology in the hopes of maximizing brain size and thus intelligence. They have especially large heads and eyes, childish body proportions and somewhat resemble a cartoon character. The result is exceedingly intelligent and surprisingly cute. They function as the scientists and intellectuals of the Imperium.
Ladies
They originate from the genes of President Mei Li. While the cult of superhumanity dominated the Imperium, some felt that physical humanity was not a very desirable trait, and that engineering should attempt to create an entirely new, superior species of intelligent life. They are efforts to do just that by balancing intelligence and empathy at the expense of physique. The result is frail but wise and cute.
Survivors
A new designation for an old brand, these are actually normal humans with balanced characteristics. The adaptive nature of the basic human form was considered by some to be worth preserving. A minority in the Imperium can be said to revere the old human genotype, though the majority tend to treat them with disdain. When the Imperium began conquering Earth and Colonial colonies, most were classified as this.
