Nestveons

Nestveons are a fictional sentient species frequently featured in worldbuilding and speculative fiction. They are defined by nest-building as a central cultural practice, a cooperative social structure with distinct builder and caretaker roles, and an architectural aesthetic that blends living growth with engineered materials.

The name Nestveon comes from nest, reflecting the species' defining activity, and the fictional suffix -veon, used in constructed languages to denote a people or collective.

Biology: Nestveons are described as medium-sized bipeds with resilient skin and dexterous limbs adapted for construction. Their life cycle often emphasizes brood care, with extended family groups supporting nesting and education.

Society and culture: Social organization is typically cooperative and caste-based. A council of master builders guides major nest expansions while elder caretakers coordinate resource distribution. Communication combines vocal signals with tactile methods and, in some settings, pheromonal cues that synchronize work.

Habitat and technology: They inhabit forested archipelagos or cliffside regions where nests can be grown as living habitats. Their technology favors sustainable materials, modular architectures, and ecological integration. Economy centers on shared resources, apprenticeship-based knowledge transfer, and cross-group trade. Diplomacy and mediation commonly resolve disputes over nesting sites.
