About Omegaverse (A/B/O)
A fanfiction-original setting in which people have a secondary designation — alpha, beta, or omega — with associated biology, instincts, and social hierarchies. Omegaverse worldbuilding varies enormously by author, and stories use the framework for everything from romance to pointed social commentary about bodies and autonomy.
The genre's appeal lies in its built-in tensions: instinct versus choice, biology versus identity, and societies whose rules characters must navigate or defy.
Common scenarios: An omega executive concealing their designation in an alpha-dominated industry, or a bonded pair negotiating what their bond means beyond what their biology dictates.
