If you're new to the term ABO or Omegaverse, I've made this simple breakdown to help you understand or enjoy the worldbuilding of ABO DESIRE more smoothly!
This sub-genre is often used in speculative fiction (especially in BL), and while it may seem wild at first, it follows its own internal logic and rules.
**this is all in a fictional world**

🔹Basic Terms in the Omegaverse
In the ABO world, people are divided into secondary genders which affect biology, behavior, and societal roles. These categories can appear in any sex:
Alpha (α)🐺
Usually dominant, strong, high-status individuals. Often driven by instinct during “ruts.” May or may not be fertile depending on the author’s world.
Beta (β)
Considered neutral and closest to regular humans. Usually don’t experience heats/ruts. Often infertile, but sometimes fertile (depends on the setting).
Omega (Ω)😺
Usually the most vulnerable and most likely to go into heat. Can get pregnant (even male omegas). Emit strong pheromones during heat that attract Alphas.
Enigma (E) (Rare unique)
A secret or rare type that doesn’t fit into the usual hierarchy but is on top of everyone. In this story, the Enigma is deeply tied to the mystery of the plot.
🔹 Key Concepts to Know
Heats (Ω):
A biological cycle omegas go through where they become extremely fertile and emit intense pheromones. It usually causes physical discomfort and emotional vulnerability unless "relieved." -Inspired from animals fr-
Ruts (α):
The Alpha equivalent of heat. A period of heightened aggression, sexual need, and focus on finding a mate may be triggered by an omega's pheromones.
Pheromones:
Scent chemicals that play a big role in attraction and dominance in the ABO world. These are unique to individuals and secondary gender types.
Suppressants:💉💊
Pills or injections used to delay or stop heats or ruts. Often used by Omegas to live more “normal” lives or hide their identity in public.
Mating Bonds:
In many ABO universes, physical or emotional intimacy can form strong bonds between individuals, sometimes even "marking" is involved (through biting or scent).
Note that a "bite" marking is known to be a permanent mark❗ once one gets a bite mark that means they could no longer form a bond with anyone in their life and their pheromones are only noticed by their bonded partner making them not able to be in an intimate relationship with anyone else. Of course some authors have their own little differences on this concept.
🔹 Fertility in the ABO Universe
In most Omegaverse stories, everyone (including males) can get pregnant.
Some authors tweak this:
→ Alphas might not be able to get pregnant at all
→ Betas are sometimes infertile or used for balance
→ Rare gender types (like Enigma) may have unique traits or abilities or they don't exist entirely
In ABO DESIRE, worldbuilding introduces the Enigma, who’s hiding their identity and this mystery is central to the story.

Some things in the Omegaverse varies from one author to another. Some go heavy on the dynamics and world politics, others focus on emotional/romantic drama.
If this is your first time diving into Omegaverse, just keep an open mind, and know it’s part of an imaginative alternate universe not a reflection of real-life biology or gender.
