Bluokan

Bluokan is a fictional humanoid species created for science fiction settings. They are native to the ocean world Bluora in the outer reaches of the Nyr system.

Physiology: Bluokan have blue-tinged skin with iridescent patterns, membrane-like gills along the neck and upper torso, and large, forward-facing eyes adapted to low light. They average 1.7 to 1.9 meters tall and have a longer lifespan than humans, typically 120 to 150 years. They breathe atmospheric air but are well adapted to aquatic environments and can swim for extended periods.

Society and culture: Bluokan society is organized into semi-autonomous communities called domes, linked by maritime routes and shared councils. Elders or Sages guide decisions, while communal ownership of resources is common. Art emphasizes sound and light; bioluminescent skin patterns serve communication and mating displays. Their science focuses on hydro and marine technologies, including tidal power, undersea agriculture, and pressure-resistant construction.

Language and communication: They use a combination of vocalizations, tactile signals, and bioluminescence. Writing systems exist as scripts that encode luminescent patterns on skin and crafted vessels.

History and relations: Bluokan history includes migrations to orbital habitats and a history of cautious diplomacy with other spacefaring species. They maintain trade networks for minerals, energy, and biotechnologies. They tend to prefer peaceful coexistence but can mobilize coordinated defense via undersea fleets.

In fiction: Bluokan appear in multiple works across science fiction media and role-playing games, often depicted as guardians of ancient oceanic technologies.
