This a abo /omegaverse fantasy world, with three primary genders alpha, beta and omega which are differentiated on the basis of pheromones. And two secondary gender male and female (who have similar physical characteristics to real world)

History - Abo came into existence due to a worldwide virus infection(in the distant past) which led to major mutation and evolved human bodies completely differently and ushered the world in the New Genesis era.

**This is a parallel world story with similar level of development to our real world **

"" In this world everyone can get pregnant or impregnate other people.""

Female omega most easily get pregnant whereas male alpha most easily impregnate others.

Pheromones - pheromones have various functions common ones are - soothing, courting, etc.

Peculiar characteristics -

# Alpha - domination pheromones (they can suppress or coerce omega, beta and alpha)

#Omega - incitation pheromones (can incite alpha(mainly), beta, omega)

#Beta - less sensitive to pheromones

***alpha and omega have dominant and recessive subtype based on pheromone level, but it is not a official classification ***

Bond /Mated pair are only alpha and omega pairs. As only they have the Estrus cycle.

Estrus cycle, highly reproductive state. (occurs once in 1-6 months for 3-10 days)

#Alphas have Rut (more aggressive, impregnation ability increases). suppressants /inhibitors used are called R-pill(less side effects).

#Omegas have Heat (more sexually activite, fever like symptoms, ability to get pregnant increases). Suppressant /Inhibitors used are called H-pill(more and serious side effects).

#Betas have no Estrus cycle.

Bonding is of two types-

#Complete Bonding -

in this both alpha and omega mark each other.

Apha bite back of omega's neck (omega gland) called 'BOND MARK' .

Omega bite Alpha's cor gland (generally present at base of ring finger of left hand) called 'RING MARK' .

Both completely bonded alpha and omega reject others except their mate.

Partial Bonding -

Alpha marks omega(common) *(alpha can forcefully mark omega against their will) *(omega can't mark alpha without their will)

Partial bonding can be overwritten by more dominant alpha.

Partially Bonded alpha can't form node with others (expect their mated omega)

Partially bonded omega reject others (different levels of symptoms in different people, lessen with time if they don't contact their alpha), have difficulty getting pregnant to other people (except their mate).

##Omega got equal rights all over the world fifty years ago due to international conventions.
