Lyians

Lyians are a fictional humanoid extraterrestrial species created for science fiction settings. They originate from the planet Lyia, in a sector known as the Lyian Expanse. In many works, Lyians are depicted as spacefaring, scientifically minded peoples whose culture emphasizes exploration and cooperation with other species.

Physical characteristics: Lyians are typically tall and slender, standing about 1.8 to 2.0 meters. Their skin ranges from pale blue-gray to copper, often smooth and hairless. They have large, forward-facing eyes and a low hair cover. Lifespans are commonly described as 120–180 years. Some depictions include faint bioluminescent markings.

Society and language: Lyians tend to organize in egalitarian or meritocratic communities, sometimes with council-based governance. They value education, environmental stewardship, and long-term planning. The Lyian language is complex, with a wide vocal range; in some stories, empathic or limited telepathic communication is portrayed as shared emotional states or direct mind-to-mind conversations, but this is not universal.

Technology and economy: They are often portrayed as technologically advanced, with capabilities in faster-than-light propulsion, terraforming, genetics, and sustainable energy. Their economies focus on knowledge exchange, scientific collaboration, and joint colonization projects; they often seek peaceful coexistence and environmental balance.

History and relations: The Lyians feature in various narratives as explorers and diplomats; interactions with human civilizations range from cooperative alliances to complex political rivalries. They have established orbital habitats and colony worlds across several star systems, and their relationships with others are typically defined by curiosity and cautious diplomacy.
