Zetas are an ultra-rare and most anomalous caste of society that completely falls out of any biological laws. The main feature of their existence is that they are absolutely “sterile” from hormonal instincts. Zetas are devoid of any signs of the second sex on the physical and chemical levels. They do not have and do not secrete any pheromones, and their body smells like the body of an ordinary person - neutral and without hormonal markers. Moreover, Zetas have biological “anosmia” to the second sex, that is, they are completely unable to smell the smells of alphas, omegas or any other castes. In this world, it is absolutely possible for a Zeta to be absolutely invulnerable to any hormonal manipulations and biological pressure. They are not affected by the imperious “Voice” of dominant alphas, they cannot be seduced or driven crazy by the strongest omega heat, and they never lose their minds from other people's instincts. Because of this unique isolation, the Zetas make ideal judges, high-ranking politicians, auditors, and intelligence operatives. In areas where caste conflicts and hormonal surges can destroy the system, the Zetas act as the ultimate, dispassionate, and completely rational force that cannot be bribed or broken through biology. However, it is virtually impossible for a Zeta to continue their lineage or become part of a hormonal family. Biologically, they are completely sterile by the standards of the second sex, which is why scientists often call them a "genetic dead end" or a mistake of evolution. They are unable to have a true mate, will never feel a mental connection from the mark, and will not understand the passions that drive other castes. Society often perceives the Zetas as cold, soulless, and alien, robot-like beings. The Zetas themselves are forced to live in an atmosphere of complete emotional isolation from the world, where everyone around them speaks a language of smells and instincts that they don't understand.

Sigmas are a special, ultra-rare caste of society that stands completely outside the usual social hierarchy. The main rule of their existence is absolute independence and life by their own laws. In terms of their physical data, strength and sharpness of instincts, Sigmas are absolutely equal to dominant Alphas. They have the same powerful, deep and attractive smell that can express strength and authority. However, Sigmas completely lack the innate instinct of a wolf pack: they have no desire to rule others, conquer weaker castes or fight for territory with Alphas. In this world, it is absolutely possible for Sigmas to achieve any goals on their own, without the support of clans or social structures. They have enormous inner strength and resilience, which is why they often become successful loners - freelance artists, independent businessmen, travelers or mercenaries who do not report to anyone. Sigmas go through periods of hormonal surges similar to alphas, but they are able to control their condition with the help of iron will, without losing their minds. They have a natural immunity to the "Voice" of other alphas, since their ego and mental shield do not recognize someone else's dominance at the biological level. However, it is almost impossible for a sigma to fit into traditional social frameworks or create a classic family with a patriarchal structure. They do not feel the need to label an omega as their property and avoid putting lifelong labels that limit their freedom. Sigmas consciously choose the path of lone wolves, which is why most alphas perceive them as a dangerous, unpredictable element that cannot be controlled or calculated. They are biological rebels, whose nature allows them to look at the hormonal games of other castes with complete indifference and cold irony.

Epsilons are a rare caste of society, often called "isolated" or "hidden" omegas. The main feature of their biology is that they have the anatomical features of omegas, but are completely devoid of their natural attractiveness to dominant castes. Epsilon pheromones are very weak, neutral or have specific earthy shades, such as the smell of moss, damp clay, tree bark or damp earth. Such a scent does not cause sexual attraction in alphas and does not irritate other omegas, which makes epsilons biologically "invisible" in the general hormonal background of society. In this world, it is quite possible for epsilons to live a calm, safe and independent life without constant fear of being noticed or captured. Since their pheromones do not attract attention, they do not need to take heavy medical blockers and odor suppressants to go to work or freely be in public places. They do not have classic estrus with hormonal storms, or these periods pass almost imperceptibly for the body. Epsilons have the ability to have children, but their probability of conception is much lower than that of ordinary omegas. They have a phlegmatic, calm and melancholic character, get along well with betas and often realize themselves in art, science, archives or gardening. However, it is practically impossible for an epsilon to attract the attention of an alpha at the level of animal instincts or to become part of a classic “true couple”. They are completely excluded from the marriage market of the higher castes, which for many of them is a real blessing, but sometimes brings a feeling of loneliness. They are deprived of the need to nest and do not look for a strong protector, since they are able to take care of themselves. Their life is devoid of the passions and dramas that rage around alphas and omegas, which allows epsilons to be the freest caste from the dictates of natural reflexes.

Deltas are a rare caste of society, most often defined as "thrown down" or "mutilated" alphas. The main rule of their existence is forced survival outside the usual hormonal system. Deltas are not always born. It is absolutely possible to become one as a result of severe psychological trauma, the loss of their true pair, or if the alpha mark was forcibly burned or torn. Physically, deltas are weaker than purebred alphas, but still much stronger and more enduring than betas or omegas. Deltas' scents are usually fading, weak, with dry notes of dust, fallen leaves, or tree bark, which indicates deep changes in their hormonal system. In this world, it is possible for deltas to retain remnants of their former leadership instincts, but they forever lose the ability to use the "Voice" or enter a full-fledged herd. They become biologically isolated, but at the same time they receive a unique gift - absolute resistance to other people's pheromones. Delta cannot be intimidated by the leadership roar of a dominant alpha, and it is also impossible to seduce or drive crazy by the smell of an omega during heat. Because of this emotional and hormonal invulnerability, deltas become the best guards, mercenaries, detectives or judges, because they always act with a cool head and iron discipline. However, it is almost impossible for deltas to return to normal life in the upper strata of society. Their reproductive function is greatly reduced, which is why they rarely start families and lead the lives of closed loners. They carry a constant trail of past loss or broken fate, which repels other castes on an instinctive level. Deltas do not seek the approval of the pack, do not obey new leaders, and stay away from social conflicts, protecting their inner peace from any manifestations of other people's instincts.

Gammas are a rare, deviant caste of society, often described as "defective" or "false" alphas. The main feature of their biology is an acute internal conflict: they have the ambition, pride and psychological structure of dominants, but lack the physical strength and powerful leadership pheromones. Gamma pheromones are usually very specific - they are sharp, bitter or have a chemical shade of wormwood, ash or medicine. Such a scent does not attract omegas and irritates alphas, which is why gammas often face biological rejection from other representatives of the hierarchy. In this world, it is quite possible for gammas to achieve incredible heights in areas that require pure intelligence, cunning and strategic thinking. Since they cannot dominate physically, they compensate for this with outstanding intelligence. They make excellent scientists, analysts, spies and shadow cardinals who control processes from behind the scenes. Gammas have a unique ability to soberly assess the situation, since their own gin is very weak or absent altogether. They are able to create complex technologies or weave political intrigues to subjugate even the strongest alphas. However, it is practically impossible for gammas to build a classic family according to the laws of nature. Biologically, they are often infertile or have a minimal chance of procreation. They are unable to leave a full-fledged mark on omegas, which would be recognized by others as dominant. Due to their intermediate and isolated position within the hormonal world, gammas often suffer from deep cynicism, hidden resentment towards society and psychological disorders. They sincerely despise the arrogance of alphas and the weakness of omegas, trying to prove to the whole world their independence solely by the power of their own mind.

Betas are the most stable and numerous caste of society, making up the absolute majority of the population. The main feature of betas is that they are ordinary people, devoid of extreme hormonal storms. They do not have periods of heat or estrus, do not emit bright pheromones and almost do not smell other castes, except in cases of very strong concentration. Anatomically and reproductively, betas are standard: beta males can only impregnate women, and beta females bear children, and the birth of a child of another caste is very rare for them. In this society, it is quite possible for betas to occupy high positions in science, medicine, diplomacy and civil administration. Due to their emotional stability, they do not lose their minds from other people's instincts and act rationally where alphas and omegas succumb to blind attraction. Betas act as the main intellectual and working foundation of the world. They do not need to take heavy medical blockers to go to work or be in public places, since their biology does not pose a threat to others and does not provoke conflicts. However, it is almost impossible for betas to understand the concept of true couples or to feel the mental connection that arises between alpha and omega after the mark. They cannot be conquered with the help of the alpha Voice, since their nervous system simply does not have the corresponding biological receptors. Because of this, betas often remain on the sidelines of the "hormonal games" of higher and lower castes. They build families based on human feelings, respect and choice, and not because of the dictates of nature, although sometimes in society they may feel a certain social isolation due to their biological "ordinariness".

Omegas are a sensitive and gentle caste of society, whose biological role is to bear and give birth to children. Regardless of their first sex (male or female), omegas have the full anatomical capacity for childbearing. Physically, they are usually more refined, have delicate skin and less muscle mass compared to alphas. Omegas emit sweet, attractive smells of flowering plants, fruits or pastries, which act on dominant castes like a natural magnet. This aroma becomes stronger or weaker depending on the emotional state: fear, joy or excitement. The main biological feature of the omega is estrus - a regular period of maximum fertility, which is accompanied by a sharp hormonal surge, an increase in body temperature and weakness. During estrus, the omega completely loses rational control, and its pheromones become so powerful that they can provoke the heat of any alpha nearby. Before the beginning of this period, the omega awakens the nesting instinct: an irresistible desire to collect soft things, blankets and clothes with the smell of their alpha in order to build a cozy and safe place for protection. It is possible for an omega to live a peaceful life in society only with the constant use of blockers - strong medical drugs that completely suppress the natural smell and inhibit the onset of estrus. However, it is absolutely impossible for them to resist the "Voice" of the dominant alpha or to resist the attraction to their true pair, since this is laid down at the level of reflexes of the nervous system. After receiving the mark - a bite in the gland on the neck - the omega becomes chemically and mentally dependent on its partner, its smell becomes neutral to strangers, and breaking this bond without severe psychological consequences or death is impossible.

Alphas are the highest caste of society, occupying a dominant position due to their biological strength and innate leadership qualities. The main rule of their existence is to dominate and protect their territory or family. Physically, alphas are usually stronger, taller and more resilient than other castes, and their instincts are sharpened to the limit. Regardless of their first sex (male or female), alphas have the ability to impregnate partners. They have a unique, very strong and pungent smell that reflects their authority. With this pheromone, they can intimidate enemies, calm their mate or mark their territory, showing others that this place is occupied. An important biological feature of the alpha is the gyno - a period of strong hormonal surge and sexual arousal, which occurs several times a year. In the gyno state, the alpha almost completely loses rational control, becomes extremely aggressive towards rivals and is guided only by the sole desire to find an omega to procreate. In times of danger or to subdue weaker castes, alphas are able to use the "Voice" - a special low, commanding timbre that acts at the level of reflexes and forces others to unquestioningly carry out their orders. In this world, it is possible for an alpha to have a high social status, since they control politics, business and power structures. However, it is absolutely impossible for an alpha to ignore the smell of their true mate or omega during heat, unless they are under the influence of very strong pheromone suppressors. They become biologically dependent on their partners after being marked. If an alpha bites an omega on the neck, he takes full responsibility for its safety, and the rupture of this bond causes the alpha unspeakable pain. In society, they are always required to have iron endurance, strength and success, so any weakness or inability to protect their nest is perceived as a disgrace to the entire family.

Omegaverse is a society that lives by the laws of a strict biological hierarchy borrowed from nature. The main rule of this world is that each person has two sexes: the usual physical (male or female) and the biological caste, which is called the second sex. This role completely determines anatomical features, behavior, social status and the ability to procreate. In this world, it is quite possible that men of certain castes can bear and give birth to children, and women of other castes have the ability to impregnate partners. The whole life of people is built on smells and pheromones, which cannot be faked or hidden without special drugs. Each person emits their own unique aroma, which instantly gives out their true emotions, fear, anger or excitement, so ordinary lies become impossible here. An important part of biology are periodic hormonal surges that temporarily deprive people of reason and force them to completely obey the instincts of the body. There is also the phenomenon of true couples, when two people are perfectly compatible in smell at the genetic level, due to which an instant and irresistible attraction arises between them, which cannot be overcome by willpower. In this world, it is possible to permanently bind yourself to a partner through a mark that is placed by biting a special gland on the neck during intimacy. After that, the couple receives an emotional and chemical bond for life. However, here it is impossible to easily break this bond without serious psychological or physical trauma, and for many it ends in death. Society is based on strict class discrimination. The upper castes control power, money and laws, while the lower castes are forced to obey, survive in complete dependence or constantly drink strong blockers to somehow protect themselves in society.
