ESTERASUL - RADRIANS

Forest clans settle beneath the darkest parts of the Emberwood canopy, where their umber coats fade almost completely into the shadow of the fir trunks. Their crowns branch wide and flat, an adaptation that lets rain run harmlessly off the antler rather than pooling in the tines the way it does on narrower crown shapes.

Because so little light reaches the forest floor, Forest Radrians rely heavily on scent and hearing over sight, and their szałasy shelters are built low and half-buried into natural hollows between roots. Clans here are the largest and most stable of any subspecies, sometimes holding the same territory for well over a century.

Mountain Radrians trade the sweeping crowns of their lowland cousins for something far more practical: a short, thickened rack strong enough to shoulder through packed snow and loose scree without splintering. Their compact frames and low centre of gravity make them the most sure-footed of any subspecies on the sheer trails of the Hollow Peaks.

Clans here are small, often no more than a family group, and territorial by necessity — the caves that give the Hollow Peaks their name are scarce and fiercely defended. Mountain clans are the only Radrians known to actively compete with other fauna, most notably the Stonehide Boar, for shelter.

Marsh Radrians are built for wading rather than running, with unusually long, slightly webbed legs that let them cross soft ground without sinking. Their antlers grow thin and wiry compared to other subspecies, and clans deliberately train moss to grow along the tines, both for camouflage and as a kind of living ornamentation passed down within a lineage.

The Marrowfen's raised walkways connecting szałasy shelters are a marsh-clan invention, rebuilt each year as the wetland shifts. Marsh clans also keep close, careful track of the region's Glimmermoth swarms, timing seasonal rites to their glow.

Constant exposure to salt spray and wind-driven sand has bleached Coastal Radrian coats to a pale, sea-glass grey, and worn their antler tines into smooth, spiralling curves unlike any other subspecies. They are lean and built for speed, covering long stretches of open shoreline as tides and food sources shift through the year.

Coastal clans are the most migratory of the six, following the tide-crab harvest up and down the Sunreach shore for most of the year before returning inland to shelter for the coldest months. This constant movement means coastal bloodlines mix more freely with Sunreach clans than any other pairing.

Tundra Radrians are the largest of all six subspecies, carrying a heavy double coat that never fully sheds and a wide, frost-rimmed crown built to intimidate rather than to display. Their enlarged vocal chamber produces a resonant call that can carry for miles across the flat, open ice — a trait unique to this population.

Because the Glassfrost offers almost no natural cover, Tundra clans travel in unusually large groups for protection against Frostfang Wolves, and their seasonal migration is the longest and most tightly coordinated of any Radrian population.

Sunreach Radrians are built for heat rather than cold: a short, close coat, oversized ears that radiate excess warmth, and tall, narrow antler tines that maximise surface area for cooling rather than defence. They are the most solitary hunters among the six subspecies, foraging alone through the interior dunes at dawn and dusk.

Sunreach clans keep smaller, more temporary szałasy shelters than any other population, built to be abandoned and rebuilt as watering holes shift with the season. Their bloodlines mix often with Coastal clans along the salt-cliff border.
