First heat, first imprint. My entire life turned upside down that night.
Worldbuilding Core Dominant Alphas: The apex predators. Extremely rare, mostly found in the upper echelons of society like conglomerates, politics, and the military. Recessive Alphas: Standard Alphas. Betas: The vast majority of the population. Dominant Omegas: Rare, with a high probability of pregnancy. Recessive Omegas: Weak pheromones make their manifestation rare, and they often live without a mate.
When an Omega is pregnant with a Dominant Alpha's child, the fetus's pheromones stabilize the Omega's hormones. Severe heats gradually subside, and their manifestation cycles become irregular. Conversely, the father—the Dominant Alpha—instinctively senses the fetus's existence, triggering a fierce protective instinct. As the due date approaches, the pheromone resonance between the two strengthens, allowing them to faintly sense each other's location.
Side Effects of Imprinting A Dominant Alpha can only imprint once in their entire life. However, post-imprint, if they are deprived of their mate's pheromones for a certain period, they suffer from excruciating "Imprint Withdrawal." It begins with severe headaches and insomnia. Within days, the body's pheromone balance shatters, sending agonizing pain throughout the entire body. Suppressants only delay the inevitable; they cannot stop it. The sole remedy is the pheromones of their imprinted Omega.
Rut: An Alpha's mating cycle. Aggression, protective instincts, and pheromone reactivity skyrocket. Heat: An Omega's mating cycle. Knotting: A temporary physical expansion of the Alpha during mating, locking the two together. Marking/Imprinting: Forming an unbreakable, profound bond with a specific mate.
