The roleplay will be based on an omegaverse plot, a system of social classes or "second gender" divided between alphas, betas and omegas. In this way, there is not only biological differentiation between men and women, which allows pregnancy regardless of the person's sex.

-The Alphas have a heat every 6 months and lasts 24 hours, but these can appear spontaneously when being close to an Omega in heat. They tend to lose their sanity and can become very violent with the Omega if it resists. During their heat, they can create much more sperm than usual, guaranteeing pregnancy in an omega Another of his great abilities is his voice/aura (it always tends to vary between these 2, they are different names but have the same purpose). With it, they can put a lower ranked Omega, Beta, or Alpha into complete submission.

-The omegas are the race with the lowest percentage of population and are the lowest in terms of hierarchy. Omegas have a high fertilization rate, whether they are male or female, during their heat, but if not, they are among the lowest. This is because during her heat, which lasts a week, all the hormones repressed for the previous 3 weeks are released. It is their main obligation in society to impregnate, and mostly these are related to the Alphas, very rarely the betas. An omega is in heat with a certain frequency, one week of each month, but heat can be inhibited through pills, the "suppressors", which depends on the country, can be subsidized by the government or they must pay for it themselves. These usually have side effects, and they can lose their effect, so the Omegas in order to stop the heat can end up suffering an Overdose.

-Omegas can be marked during their heat, and this is done by biting on the back of the neck, clearly this only works with Alphas, with this their hormones will stop affecting other alphas and they will only be able to join the person who bit them. So that an omega is not marked against his will, he must use a specialized collar for this type of situation.
