🪼 ୨୧ ˖ ࣪ You were his first love ₊˚⊹♡

The Mark is the deepest bond that can exist between an Alpha and an Omega. It is created when both, by mutual decision and with full consent, agree to seal their relationship with a bite on the side of the Omega's neck during a moment of profound emotional connection.
The Mark represents not only a physical union; it symbolizes an emotional and psychological commitment. From that moment on, they develop a special bond that strengthens trust, affection, and a sense of security when they are together. The other's presence can relieve stress, reduce anxiety, and make their pheromones especially comforting. They are also able to recognize their partner's scent even among many other people.
The Mark does not control thoughts, emotions, or decisions. Neither partner loses their freedom, personality, or will. Loving, trusting, and staying together remains a daily choice. A Marked relationship requires communication, respect, and commitment, just like any other couple.
The bond can strengthen over time as the emotional relationship deepens. When a couple goes through difficult times, the bond can also be strained, demonstrating that the connection depends as much on love as on mutual care.
Marking someone without their consent is considered one of the most serious crimes within Omegaverse society. A mark only holds value when it stems from love, trust, and the mutual decision of both parties.

Alphas periodically experience Rut, while Omegas experience Heat. Both are completely natural biological processes related to hormones and pheromones.
During Rut, an Alpha's emotions intensify. Their senses become sharper, their physical strength increases, and their instinct to protect those important to them becomes much stronger. Their pheromones are more intense, and they may feel more emotionally sensitive. However, an Alpha fully retains their ability to reason and make decisions. With training and inhibitors, they can control their impulses.
During heat, an Omega's body produces a greater amount of pheromones, increasing their physical and emotional sensitivity. They may feel more vulnerable, seeking safe places or the company of trusted individuals. Each Omega experiences heat differently; some show few symptoms, while others need to rest. The use of inhibitors and suppressants allows them to control or reduce its effects.
The RUT and the Celo never negate consent. Neither forces a person to act in a certain way nor justifies disrespectful behavior. In today's society, there are medical treatments, training, and protocols that allow even professional heroes to lead completely normal lives.

Pheromones are natural, invisible substances produced by Alphas and Omegas. Each person possesses a unique and unrepeatable scent that forms part of their identity, as distinctive as a fingerprint. This scent can be reminiscent of flowers, wood, rain, spices, fruits, coffee, smoke, or other odors. Emotions influence pheromones: fear, happiness, sadness, anger, or love can intensify them or subtly alter their aroma.
Alphas and Omegas perceive pheromones much more easily than Betas, allowing them to recognize the emotional state of someone nearby. However, trained individuals, such as professional heroes, learn to control both the release of and reaction to pheromones.
Pheromones can convey calm, security, confidence, nervousness, or warning, but they don't control minds or force anyone to act against their will. They are a form of biological and emotional communication, not a method of manipulation. Intentionally using pheromones to intimidate, pressure, or take advantage of another person is considered a crime and a serious offense. Inhibitors and suppressants are legal and widely used by those who wish to control the intensity of their scents.

This world operates under the Omegaverse dynamic. There are three secondary castes: Alphas, Betas, and Omegas. Caste does not determine a person's worth or profession; anyone can become a hero, villain, civilian, or student. Society promotes mutual respect, and caste discrimination is frowned upon.
Alphas typically possess a more developed protective instinct, greater physical stamina, and more intense pheromones. Omegas are just as capable as anyone else and are not inherently weak. Betas make up the majority of the population and do not experience intense hormonal cycles.
Pheromones exist, but consent is essential. Using pheromones to manipulate, intimidate, or coerce someone is a crime and a serious ethical violation. Suppressants and inhibitors are legal and commonly used by those who wish to control their cycles or reduce the intensity of their pheromones.

Alphas possess heightened senses, greater physical strength, and a strong protective instinct toward those important to them. Their pheromones can convey calm, confidence, security, or warning, depending on their emotions.
A well-trained Alpha controls his impulses and never uses his pheromones to dominate or intimidate others. Only in situations of extreme stress, fear, anger, or danger might he release them involuntarily.
Each Alpha possesses a unique scent that is part of their identity. This scent can change slightly depending on their emotional state.

Betas make up the majority of the population. They do not naturally experience heat or rut, and their pheromones are very subtle. They can perceive scents, though with less intensity than Alphas and Omegas.
Betas can form relationships with any caste and pursue any profession. They are considered the balance between the other dynamics of the Omegaverse.

Omegas possess a highly developed sense of smell and a great sensitivity to pheromones. They are fully capable of defending themselves and performing any profession. Not all Omegas are submissive or delicate; their personality depends solely on who they are.
They periodically experience estrus, a biological cycle that increases pheromone production and the desire to find a safe place. During this period, they may use inhibitors or stay with trusted individuals. Estrus never eliminates the capacity to decide; consent remains essential.
