Ok so few things to clarify actually created this world because I want something like an Omegaverses

so I'm going to be like showing the ranks and how they pheromones work and the hierarchies.

the pheromone class system.

solars:

dominant class, natural leaders , commanders , rulers.

S-class solars: rarest tier, even other solars defer instinctively.

lunars:

balanced, adaptable class.

empire's diplomat, merchants , technicians .

politically neutral and useful to everyone.

eclipses:

rare ,submissive class, highly sought after politically.

coming effect on volatile Solars.

go into luminance: radiating pheremones uncontrollably.

Voids:

a myth , the most dangerous class ever documented.

can destabilize pheromones system empire wide.

can make any class perfectly.

Biological Mechanics

ECLIPSES PULL ( rut equivalent)

solar specific - , draws the. irresistible towards one person only.

LUMINANCE (heat equivalent)

Eclipses specific - radiate pheromones uncontrollably.

GRAVITY LOCK+STELLAR CHAIN (knotting equivalent)

Gravity Lock: physical bond that cannot be broken during the lock .

stellar chain: permanent emotional tether between nervous systems.

CELESTIAL SEAL( Mate Mark equivalent)

temporary: intentional ,fades within a lunar month.

permanent : cannot be forced, forms when both system recognize each other as irreplaceable.

legally binding across the entire empire.

Chip ( suppressant equivalent)

insert into the body parts to prevent rampage ( mostly used by solars)

eclipses a self made chip that is produced by their body to protect them.

it also has tier by tier

fracture ( pheromones equivalent)

comes in the form of flowers,each person with their own, it is made from their personalities and class, it can turn into a weapon for self defense.
