Fauna of Esterasul

Radrians share every region of Esterasul with other wildlife — some predators, some prey, some cultivated alongside the clans. This archive is ordered by region and expands as new species are recorded.

The Emberwood · Small game

Duskhare

A large-eared forest hare active at dusk, often kept semi-domesticated by Forest clans for its wool-like undercoat.

Size: rabbit-sized · Diet: herbivore · Relationship: semi-domesticated
+ Read full entry Collapse entry

The Duskhare is a large-eared forest hare, active mainly at dusk, when its dappled coat blends almost perfectly with the low light filtering through the Emberwood canopy. Rather than hunting it, most Forest clans keep small semi-domesticated groups near their szałasy for its dense, wool-like undercoat, sheared rather than harvested.

Duskhares are unusually tolerant of Radrian company, likely because Forest clans have kept them for so many generations that a mild, mutual trust has developed between the two species.

The Emberwood & Hollow Peaks · Predator

Emberlynx

A tufted-eared cat with rust-coloured fur that ambushes from low branches, the main predator of young Forest Radrian calves.

Size: medium predator · Diet: carnivore · Relationship: predator
+ Read full entry Collapse entry

The Emberlynx is a solitary, tufted-eared cat with rust-red fur that all but disappears against the Emberwood's fallen needles. It hunts by ambush, dropping from low branches onto unwary prey, and is the primary natural predator of young Forest Radrian calves during their first vulnerable months.

Forest clans post lookouts near calving grounds specifically to watch for Emberlynx movement, and a calf's earliest lessons often centre on recognising the low, coughing call the cat makes before a strike.

The Marrowfen Marshes · Grazer

Mossback Turtle-Stag

A slow, heavily-shelled grazer whose shell hosts a permanent garden of moss and small flowers, considered good luck by Marsh clans.

Size: large, slow · Diet: herbivore · Relationship: revered, unbothered
+ Read full entry Collapse entry

The Mossback Turtle-Stag is a slow, heavily-shelled grazer whose domed shell hosts a permanent, self-sustaining garden of moss and small marsh flowers, cultivated by nothing but time and humidity. It poses no threat to Radrians and is rarely hunted, moving through the Marrowfen at its own unhurried pace.

Marsh clans consider a Mossback sighting good luck, particularly during calving season, and it's common for a newborn calf to be named for whatever small flower happened to be blooming on the shell of the nearest Mossback that day.

The Marrowfen Marshes · Pollinator

Glimmermoth Swarm

Bioluminescent moths that swarm the marsh at dusk in enormous numbers, used by Marsh clans as both light source and calendar marker.

Size: swarm insect · Diet: nectar · Relationship: cultivated
+ Read full entry Collapse entry

Glimmermoths are small, bioluminescent moths that gather in vast swarms over the Marrowfen at dusk, their pale green glow bright enough to light the raised walkways between szałasy shelters. Marsh clans deliberately cultivate the moss gardens the moths feed on, ensuring the swarms return to the same stretches of marsh each year.

Beyond their practical use as a light source, swarm timing is reliable enough that Marsh clans use the first major Glimmermoth gathering of the season to mark the start of several seasonal rites.

The Hollow Peaks · Prey / rival

Stonehide Boar

A thick-plated boar that competes directly with Mountain clans for root vegetables and cave shelter.

Size: large, armoured · Diet: omnivore · Relationship: territorial rival
+ Read full entry Collapse entry

The Stonehide Boar is a heavily-plated, omnivorous animal built for the same harsh terrain Mountain Radrians call home — and unfortunately for both species, it wants many of the same things: sheltered caves and the same scarce root vegetables that survive the Hollow Peaks' cold.

The resulting rivalry is old and mostly a matter of posturing rather than open conflict; a Mountain clan and a resident boar will often simply avoid the same territory at the same time of day, an uneasy truce repeated season after season.

The Glassfrost Tundra · Predator

Frostfang Wolf

A pack-hunting wolf with a frost-pale coat, the primary predator of the open tundra.

Size: large predator · Diet: carnivore · Relationship: apex predator
+ Read full entry Collapse entry

Frostfang Wolves hunt in coordinated packs across the open Glassfrost Tundra, their pale coats making them nearly invisible against the ice until they're already close. They are the tundra's apex predator and the single biggest reason Tundra Radrians migrate in such unusually large groups.

A lone Radrian on the open ice is genuinely vulnerable to a Frostfang pack, which is why Tundra clans treat group cohesion during migration as a matter of survival rather than tradition.

The Sunreach Dunes · Small game

Sandrunner Lizard

A fast, heat-tolerant lizard that burrows during the day and is hunted opportunistically by Sunreach clans at dusk.

Size: small · Diet: insectivore · Relationship: opportunistic prey
+ Read full entry Collapse entry

The Sandrunner is a small, extremely fast lizard that spends the hottest part of the day burrowed beneath the dune surface, emerging to hunt insects at dusk — the same hours Sunreach Radrians are most active, which makes the two species frequent, if opportunistic, rivals for the same window of activity.

Sunreach clans occasionally forage Sandrunners as a supplement to their root-vegetable diet, though the lizard's speed makes it far from a reliable food source.

The Sunreach Shore · Foraged

Tidecrab Colony

Large shore crabs harvested by Coastal clans during low tide, an important seasonal food source.

Size: hand-sized · Diet: scavenger · Relationship: foraged food source
+ Read full entry Collapse entry

Tidecrab colonies cluster along the tide pools beneath the Sunreach salt cliffs, scavenging whatever the tide leaves behind. They surface in the greatest numbers during the lowest tides of the year, and Coastal Radrian clans time much of their seasonal migration specifically around this harvest.

The tidecrab is one of the few animal proteins that appears regularly in a Radrian diet, and coastal clans have developed careful, sustainable harvesting customs to keep the colonies returning year after year.
