Status: Extant
Pelagians are a sapient amphibious humanoid species originating from the oceanic environments of The Eden Reach.
Adapted for life both beneath the water and on land, Pelagians possess a combination of aquatic and terrestrial biological characteristics. They are capable of living permanently outside water, although most Pelagians remain biologically more comfortable within humid or aquatic environments.
Pelagian civilisation is particularly associated with the enormous oceans of Eden Reach, where settlements ranging from coastal cities to completely submerged population centres have existed for thousands of years.
They are also one of the species possessing some of the oldest surviving traditions concerning Eden and the legendary First Garden.
Appearance
Pelagians possess a humanoid body structure with two arms, two legs, and facial anatomy broadly recognisable to other humanoid species.
Their aquatic adaptations nevertheless make them immediately distinguishable from humans.
Pelagian skin is smooth and naturally resistant to prolonged water exposure. Colouration varies considerably, including pale blue, blue-grey, turquoise, sea-green, grey, and darker oceanic tones.
Subtle patterns are common across the skin.
These may appear as spots, stripes, gradients, or irregular markings and are particularly common around the face, shoulders, arms, sides, and back.
Pelagian eyes are generally larger than human eyes and adapted for underwater vision.
Eye colours vary widely and can include blue, green, turquoise, silver, amber, violet, and extremely dark shades.
Their pupils can expand considerably in low-light environments.
Small gill structures are located along the sides of the neck. When closed, these resemble several thin lines or slits and can be surprisingly subtle from a distance.
Pelagians possess ordinary humanoid legs rather than tails and can move naturally on land.
Amphibious Biology
Pelagians possess both lungs and specialised gill structures.
Their lungs allow them to breathe atmospheric oxygen normally, while their gills extract dissolved oxygen from water.
The respiratory systems work alongside one another rather than functioning as completely separate biological mechanisms.
This allows Pelagians to transition between terrestrial and aquatic environments without requiring external breathing equipment.
Water quality remains important.
Polluted, chemically hostile, or oxygen-poor water can overwhelm their natural filtration systems and require specialised breathing equipment.
Skin
Pelagian skin contains specialised glands that maintain a thin protective layer of moisture across the body.
This protects against infection, regulates temperature, and prevents damage caused by prolonged exposure to water.
The same adaptation creates difficulties in exceptionally dry environments.
Pelagians can survive normally on land, but prolonged exposure to extremely dry climates may cause skin irritation, dehydration, respiratory discomfort, and eventually more serious medical problems.
Pelagians living on dry worlds commonly use moisturising compounds, hydration systems, specialised clothing, or humidified living spaces.
Underwater Vision
Pelagian eyes are adapted to function both above and below water.
Their eyes can compensate for changes in light refraction when transitioning between environments, allowing them to maintain clear vision underwater without goggles or other equipment.
They possess particularly strong low-light vision.
This adaptation originated in deeper ocean environments where natural light could be extremely limited.
Sudden exposure to intense light can temporarily cause discomfort.
Hearing
Pelagian hearing functions differently from that of most terrestrial humanoids.
Their auditory system is capable of detecting vibrations effectively through both air and water.
Underwater, Pelagians can determine the direction and approximate distance of sounds with remarkable accuracy.
Some populations developed communication traditions incorporating extremely low-frequency sounds capable of travelling considerable distances through water.
Modern communication technology has largely removed the practical necessity of these methods, although they remain culturally significant.
Swimming
Pelagians are exceptionally powerful swimmers.
Their skeletal structure, musculature, lung capacity, and distribution of body fat are adapted for efficient movement through water.
Small amounts of webbing are present between the fingers and toes.
This webbing is flexible enough that it causes little interference with ordinary tool use.
Pelagians can remain submerged indefinitely in sufficiently oxygenated water.
Pressure Resistance
Pelagian bodies tolerate underwater pressure considerably better than humans.
This allows them to descend to substantial depths without specialised equipment.
Their natural resistance has limits.
The deepest regions of ocean worlds still require pressure suits, vehicles, or reinforced habitats.
Different Pelagian populations possess varying degrees of pressure tolerance depending upon the environments in which their ancestors evolved.
Temperature
Pelagians regulate body temperature efficiently in water, where heat is lost considerably faster than in air.
Their circulation can redirect blood flow away from exposed areas while maintaining the function of critical organs.
This provides moderate resistance to cold water.
They are not adapted to extreme cold in the same manner as Glacians.
Likewise, Pelagians can tolerate warm tropical waters but remain vulnerable to extreme heat.
The Oceans of Eden Reach
Pelagians are believed to have originated on one of the ancient oceanic worlds of The Eden Reach.
Their early civilisation developed primarily beneath the water rather than along coastlines.
Natural underwater caverns, reefs, volcanic formations, and later artificial structures became the foundations of early Pelagian settlements.
Modern Pelagian cities can extend across enormous sections of the seafloor.
Some contain pressurised dry environments for terrestrial visitors, while others remain almost completely flooded.
Architecture
Pelagian architecture is designed around three-dimensional movement.
Unlike terrestrial cities, where movement occurs primarily across horizontal surfaces, underwater settlements may contain entrances, pathways, structures, and public spaces accessible from almost any direction.
A building may possess entrances on its roof, walls, underside, and upper levels because Pelagians can simply swim between them.
This can make traditional Pelagian cities extremely confusing for terrestrial visitors.
Modern mixed-species settlements incorporate conventional walkways, elevators, pressurised chambers, and dry districts.
Culture
There is no single Pelagian culture.
Pelagian populations exist across numerous worlds and possess their own languages, traditions, governments, religions, and identities.
The ocean nevertheless holds enormous cultural significance throughout many Pelagian societies.
Water is commonly associated with ancestry, migration, memory, and connection.
Many traditional Pelagian stories describe oceans not as barriers separating places, but as pathways connecting them.
The First Garden
Some of the oldest Pelagian traditions contain stories concerning a place sometimes translated as the First Garden.
Descriptions vary enormously between cultures.
Some describe it as the birthplace of all living things.
Others describe an ancient ocean from which life spread outward.
Certain traditions claim that all seas are ultimately connected through something deeper than physical space.
For most of Pelagian history, these stories were regarded primarily as mythology, religion, or cultural metaphor.
Scientific discoveries surrounding Eden have caused some researchers to reconsider whether these traditions contain distant cultural memories of events associated with the spread of life throughout Eden Reach.
No direct connection has been proven.
Pelagians themselves possess no universally accepted explanation for the traditions.
Relationship with Eden
Pelagians do not possess secret knowledge explaining Eden.
Their connection to the mystery primarily exists through extremely old traditions and biological history.
Some Pelagian organisms possess genetic characteristics that have contributed to research surrounding the controversial Eden Hypothesis.
Whether these similarities indicate common ancestry, ancient biological transfer, or something more unusual remains unknown.
Pelagians Outside Eden Reach
Pelagians have spread far beyond their ancestral region.
Ocean planets are particularly attractive destinations, although substantial Pelagian populations also exist on conventional terrestrial worlds.
Aquatic districts can be found within some major mixed-species cities.
Pelagians work throughout science, medicine, exploration, engineering, trade, military service, government, industry, and countless other professions.
Their natural abilities make them particularly effective in underwater environments, although occupation is not determined by species.
Space Travel
Despite originating beneath oceans, Pelagians adapted successfully to space travel.
Modern spacecraft designed for Pelagian crews generally maintain higher atmospheric humidity than human vessels.
Some specialised ships contain flooded recreational spaces or entirely aquatic sections.
Completely water-filled spacecraft are uncommon because of the enormous additional mass involved.
Mixed-species vessels generally require only minor environmental modifications to accommodate Pelagian personnel.
Relations with Other Species
Pelagians live alongside Humans, Androids, Glacians, Ashens, Elysarians, Sylvans, and numerous other species.
Their amphibious biology occasionally requires environmental accommodations, but this rarely prevents integration into mixed-species communities.
Pelagian settlements on aquatic worlds frequently serve as important centres for marine science, biological research, food production, and underwater resource extraction.
Identity
Pelagian identity varies considerably between individuals and communities.
Some maintain strong connections to the ancient cultures of Eden Reach.
Others descend from populations that left the region generations ago.
A Pelagian born on an ocean world within the Core Systems may consider that world their homeland rather than Eden Reach.
As with other widespread species, biology does not determine political allegiance or culture.
