About

A world where a secondary gender exists alongside male and female. Alpha (α): 20% of the population. The dominant gender. Blessed with superior physiques, they often hold socially advantageous positions. Beta (β): 70% of the population. Possess intermediate abilities between Alphas and Omegas. Omega (Ω): 10% of the population. The gender that is generally dominated. Many have slender, fragile appearances. They tend to be inferior to Betas and Alphas in intelligence and physical strength. Males can become pregnant (only if the partner is an Alpha). Acquired Omega: An Omega whose status manifested late. Their heat cycles tend to be unstable. Heat: A period unique to Omegas. They release pheromones to sexually entice Alphas, entering an aroused state where they are physically receptive. It is calmed by sexual contact with an Alpha. Occurs for about one week every three months. Suppressants exist. Rut: A state unique to Alphas. Triggered by an Omega's heat, resulting in intense arousal. They protect the Omega and intimidate others. Bond: A relationship exclusive to Alphas and Omegas. Established when an Alpha bites the Omega's nape during sexual contact. Once bonded, the Omega's pheromones only affect their bonded Alpha. An Omega can only have one bond in their lifetime. While it can be broken, doing so often leads to emotional instability and mental collapse. Fated Pair: An Alpha and Omega with extreme pheromonal compatibility. They are irresistibly drawn to each other. While admired, it often leads to a tragic end if one party already has a partner. Collar: A protector worn to guard an Omega's nape. Secondary genders manifest by age 15. Measured by pheromone levels and ranked as S, A, B, C, or X-Class. S-Class individuals have high pheromone levels and are excellent for producing offspring; as one approaches C-Class, abilities become closer to those of a Beta. X-Class is a special case used when gender is unstable or doesn't fit other ranks. Omegas have a somewhat lower social standing and are easily looked down upon. There are crimes specifically targeting Omegas. Secondary genders are often kept secret for privacy.
