I hate the omegaverse :D

As humans developed wisdom, they separated into three subspecies

The φ—Phi (instead of alphas)
the χ — Chi (instead of betas)
and the ψ — Psi (instead of omegas)

Each one has its own characteristics, developments, and instincts, different from each other.

There are some general characteristics such as:

The majority of the city's population is female, with a distribution of 75% women and 25% men.

Although the technologies are modern, the houses are made of old brick and wooden roofs, the weapons are still armor and swords, the towns are protected by walls, and markets, merchants on horseback and carts still exist, and some deals are unethical.

Furthermore, these three populations live in constant armed conflicts.

The three species are recognizable because they emit a characteristic odor that defines them.

They all make logical sense, but they also have instincts that modify them.

BUT something interesting is that when the genetics of each subspecies detects that there are few individuals, it generates a need to reproduce and prevents them from going into conflicts with others to avoid extinction

(my favorites and pampered ones)

These were born from a combination of Psi and Phi, but managed to develop their own completely stable genetic makeup.

These individuals are the midpoint between offense and defense, but their most remarkable ability is their intelligence, being the most intelligent sub-sub, but also somewhat eerie.

Furthermore, they have the distinction of being the most abundant humans on the planet, since they do not experience too many losses and their reproduction rate is the same as that of normal humans.

Their societies are quite technologically advanced, employing a combination of defense and offense, but primarily prioritizing technological improvement above all else.

But aside from all the good things, they take advantage of the wars between the Psi and the Phi to plunder unprotected villages, with some Chi villages kidnapping teenagers from both subspecies for experimentation.

Thanks to their intelligence and by experimenting with adult individuals (allowing adolescents to grow up so that their striking characteristics could develop perfectly) of both species, or with dead and donated individuals (depending on the village and only the Psi donate), they managed to develop a perfume capable of smelling like the Phi and thus being able to infiltrate their villages to investigate and carry out other actions

They also developed a synthetic Psi skin to reinforce as much as possible.

Although such experiences are found throughout the Chi, there are regions of Chi that oppose experimenting on live and abducted individuals.

This led to a long war between the Chi peoples

The most important one was: "The Night of the Singing Dead"

These were the first subspecies to be genetically and socially stable

These are beings that are extremely violent and aggressive towards Chi and Psi.

Their main characteristics would be that they have great strength, larger and rougher hands for more effective killing, greater height, and a certain something about abusing the inhabitants of the villages they attack.

They have an instinct that makes them develop aggression and violence towards others who do not have their same Phi scent.

Although they are mostly women, men are indeed present in the wars, as some women are caring for the babies, since Phi women have 11 months of pregnancy, but with two babies of at least

The problem is that they become extremely violent as the pregnancy progresses, even with their family, right up until postpartum.

even going so far as to kill someone

The problem is that the Phi feel guilt when they kill someone of their own kind, which leads them to extreme isolation and suicide.

That's why infant mortality is quite high, even though it's a small number.

In terms of weaponry, they are underdeveloped, as they only need their hands to be dangerous.

Even so, they're not stupid; they're the second smartest.

They are able to detect when a Phi infiltrates their villages just by observing their anatomy, behavior, way of speaking, etc.

That's when the smell makes them say "it's another Phi"

These are the second to establish themselves as a subspecies

These societies are more defensive; their villages are more fortified with almost immovable rock walls.

Their characteristics include very tough skin, super hard bones, a body system that causes bleeding to clot much faster when a wound occurs, and considerable resistance to strong blows.

But they are still mortal, so yes, they can die.

Their instinct tells them they must protect everyone in need, regardless of friend or foe, which leads to problems

Women have 7-month pregnancies, with a high probability of becoming pregnant with more than one baby, but needing plenty of food and nutrients.

These are the least intelligent of the three, but they are not stupid; they still have reasoning abilities despite their instincts.

This was a terrible war between Chi peoples so that a scientific philosophy could win.

"Experimenting on living beings yields better advances" versus "experimenting on deceased donors is more moral"

But the worst part was when those who supported experimentation on living individuals began leading battalions of Phi towards the Chi villages that supported experimentation on dead people, which unleashed an absurd number of deaths in those villages.

But what gave it that name is that when the corpses were examined, they would begin to hum a distorted and eerie melody, due to the situation and how guttural it was.

That was so terrifyingly illogical that it led to an agreement among the Chi to prevent it from happening again: each village can investigate in its own way only if it shares its knowledge, something that is respected by all to avoid a similar event.

To this day, nobody knows what happened; it's just a story told by the Chi with a blood-curdling respect.
