Hello! This is the author, providing you with a description of some Omegaverse terms and a quick background on how this universe came to be. To those who are already familiar, do know that this work diverts from some commonly established elements while retaining others. I took liberties and did changes depending on how I see fit.

Omegaverse is an alternate universe wherein mankind evolved secondary genders as a response to consistently low birth rates. These sub-genders follow the social hierarchy of wolves, namely: alpha, beta, omega (A/B/O).

sub-gender considered to be at the highest rank, although few in numbers. They are known to be stronger, bigger, and smarter (or generally better) than most people, an adaptation to the need to protect and provide for their pack. They enter a period of heightened sexual activity and arousal, called rutting (or rut), four times a year wherein they lose control and only act upon the need to procreate. To ensure higher success in reproduction, the base of an alpha’s organ will swell during mating before ejaculation (knotting/knot). Alphas are extremely territorial and will be combative if threatened.

sub-gender with the largest population. They are considered "normal" with no special characteristics like alphas and omegas. They can not bond and do not enter into heat/rut. They also have weaker pheromones and in turn, are less affected, allowing them to thrive in industries where being unfazed by pheromones is needed.

sub-gender considered to be the fertile counterpart of alphas, with both male and female capable of carrying life. They generally have attractive features and are known to be physically weaker and smaller than most people. Like alphas, they also enter a period of heightened libido, called heat, once a month wherein they will lose bodily control in favor of copulating. To feel safe and secure, omegas create a “nest” usually filled with soft things and possessions from loved ones. Entering or touching a nest without the omega’s permission will cause the omega extreme distress and some may even attack. Various laws and safety measures are put in place to protect the omegas who are even fewer in numbers than alphas.

personal scent that conveys a person’s emotion. The pheromones of alphas and omegas in rut/heat can induce sexual desire upon others except for blood-related family members. Scent-marking is used to display possessive behavior. Scent patches can be used to block or minimize pheromones.

medicine developed to restrain an alpha’s rut and omega’s heat, delaying it entirely or allowing them the awareness that is otherwise lost during this period.

made by biting an alpha or omega on their scent glands to make them mates or lifetime partners. Once a bond is established, only mates are affected by each other’s heat/rut and Command. This is akin to marriage and must be registered to the government.

unique ability of alphas to compel an omega. An alpha that successfully manages to repeatedly Command an omega will make them enter subspace and gain absolute control. It was made illegal to Command omegas without consent, especially to unbonded omegas unless in extremely rare situations (e.g., an omega going feral in public)

a self-induced coma-like state that happens when an alpha or omega is rejected by their mate.

an alpha formally inviting an omega to be mates, often by gifting food or desired items marked with the alpha’s scent. This is meant to display an alpha’s capabilities of providing for and protecting the omega.
