Sorry I made an summary of my original explanation using ChatGPT 😅
But in short everything that’s explained in this comment you learn overtime reading all kinds of abo story’s
So just ask if there’s something you don’t understand or if you need more details about it.
The
A/B/O world, also called
Omegaverse, is a fictional setting where people are categorized into three biological/social types:
Alphas
Often portrayed as leaders or protectors. They are typically dominant in society and have strong instincts tied to bonds and territory.
Betas
Considered the “middle” group. They usually don’t have strong instincts or special biological traits and often function like people in the real world.
Omegas
Often shown as rarer and physically less dominant. In many stories, they face social vulnerability or discrimination, which becomes an important theme
Pheromones & Scents
- Omegas smell sweeter or softer
- Alphas smell stronger or sharper
- Heat and rut dramatically increase scent strength
- Scent blockers and suppressants exist
- Close-range scent detection is intimate
Some characters can recognize specific individuals by scent alone.
Heat (omegas)
What heat is
- omega pheromones intensify
- sexual drive increases
- physical discomfort occurs
- Can be suppressed with medication
- Is dangerous if unmanaged in some stories
During heat, omegas may:
- have trouble controlling pheromones
- feel physically weak
- crave comfort or intimacy
Rut (alphas)
What rut is
During rut:
- libido spikes
- pheromones intensify
- possessiveness increases
- aggression threshold lowers
- Can be triggered by omega heat pheromones
- Can be suppressed or medically treated
- Often requires isolation if unmanaged
What “marking” is in an A/B/O world
A
marking bite is a
biological and pheromonal act where an alpha (sometimes an omega, depending on the world) bites a specific scent gland area on their partner — most commonly the
neck, sometimes the
shoulder or wrist.
- Mixes scents
- alters how the marked person’s body responds to others
- establishes a recognized bond or claim
Why the neck?
In most A/B/O rulesets:
- the neck has high pheromone sensitivity
- it’s close to scent glands
- it allows rapid pheromone absorption
That’s why it’s:
- biologically effective
- socially intimate
- symbolically vulnerable
Letting someone bite there is usually a
huge trust signal.
What happens biologically after a marking bite
Once a bite occurs, several things usually happen:
Immediate effects
- surge of pheromonal exchange
- calming or grounding response
- reduction in heat/rut intensity
- emotional clarity or reassurance
- the alpha becomes more attuned to the omega’s emotional state
- outside alphas may sense “claimed” pheromones and back off
What marking means socially
In-universe, a mark often signals:
- “This omega is bonded”
- “This alpha has a partner”
- “Do not interfere”
- “This pair is recognized”
Depending on the setting, a mark can be:
- equivalent to marriage
- a pre-bond or engagement
- legally binding
- socially scandalous if done without approval
- Claiming
- Protection
- Mating
- Trust
