Field Guide · Riding and Travel

Mounts

Six domesticated mounts fill distinct niches, from rapid-response work and river travel to caravans and comfortable household journeys.

6 entriesRidingTravel
Utahraptor
Hookclaw · Predatory Riding Mount

Utahraptor

The Range's primary fast working mount, used for scouting, livestock cutting, rapid response, and difficult terrain.

Length
About 5–7 m
Glow
Blue-green, amber, or pale violet markings
Temperament
Intelligent, powerful, trust-dependent

Field note: A steady animal is evidence of the rider's skill. Partnership matters more than docility.

Dilophosaurus
Twincrest · Light Riding Mount

Dilophosaurus

A speed-and-distance specialist favored for courier runs, patrols, scouting, and personal travel.

Best for
Fast travel and light loads
Glow
Crest edging, eye marks, and neck bands
Temperament

Field note: It notices trouble quickly. An inexperienced rider may learn that after the mount has already left.

Parasaurolophus
Longcrest · Herd and Riding Stock

Parasaurolophus

Versatile domestic stock raised for range leather, breeding, meat, and carefully selected riding lines.

Primary product
Durable range leather
Other roles
Herd stock, riding, caravan work
Glow
Crest light, flank constellations, body bands

Field note: A prized riding animal is not interchangeable with production stock merely because the species serves both roles.

Sailrunner
Aquatic Working Mount

Sailrunner

A domesticated spinosaurid used for river travel, fishing work, wetland routes, patrols, and light riding.

Best for
Water and muddy terrain
Working role
Drives fish toward nets and traps

Field note: A disciplined Sailrunner can herd fish without shredding the nets, which is the difference between help and aquatic vandalism.

Cavern Crestback
Crestback · Long-Distance Travel Mount

Cavern Crestback

A patient, sure-footed caravan mount built for endurance, pack transport, and difficult regional routes.

Length
About 4.8–6.5 m
Weight
About 900–1,400 kg

Crest spines, neck, flanks, and tail

Field note: Not fast. Dependable. It crossed the bad bridge, carried the supplies, and arrived.

Europasaurus, known in the Range as a Long Neck
Long Neck · Small Sauropod Riding Mount

Europasaurus

A gentle household mount valued for smooth regional travel, family journeys, social visits, and unusually high rider comfort.

Length
About 5.5–6.5 m
Glow
Usually continuous along the neck, shoulders, flanks, and tail

Lumen-Horn Bison

Massive, gentle herd animals supporting the Range's milk, cream, cheese, meat, hide, and breeding economy.

Shoulder
About 2.0–2.4 m
Weight
About 1,100–1,800 kg
Glow
Horns, shoulders, flanks, neck, and tail

Field note: A healthy dairy herd signals water, pasture, labor, veterinary skill, and long-term stability.

Field Guide · Skilled Partners

Working Animals

Animals trained for herd control, guarding, messages, settlement work, and specialized pest catching.

4 entriesTrainingPractical roles
Dire Wolf
Working Canid

Dire Wolf

The primary herding and livestock-guarding animal, bred for focus, recall, steady nerves, and controlled prey drive.

Best for
Fine herd control, guarding, night patrol
Glow
Shoulders, flanks, spine, and tail base
Handling
Control, not combat

Field note: A good wolf knows the difference between work animals, prey, and actual threats.

Malabar Large-Spotted Civet
Pest Control and Companion

Malabar Large-Spotted Civet

An intelligent settlement worker that patrols homes, greenhouses, warehouses, inns, and food stores for pests.

Length
Body 60–80 cm; tail 45–60 cm
Weight
About 5–9 kg
Temperament
Curious, social, affectionate with trusted people

Field note: Useful enough to justify itself economically, charming enough to end up sleeping on the bed.

Paradise Parrot
Messenger Bird and Companion

Paradise Parrot

A rare, highly trainable route-finder used to carry lightweight messages between familiar roosts.

Height
About 25–35 cm
Weight
About 80–140 g
Glow
Chest, shoulders, wings, and tail

Field note: A beautiful bird distracted by every glowing fungus is still a poor messenger.

Tilcayo
Specialized Pest Catcher

Tilcayo

A working animal used to find and remove pests around settled spaces and stored goods.

Primary role
Pest catching
Category
Working Animal
Profile status
Core role established

Field note: The working role is canon. Additional anatomy, size, temperament, and glow notes can be added when its full profile is written.

Field Guide · Hearthside

Companions

Small animals whose practical jobs have a suspicious habit of becoming emotional attachments.

Field note: It may protect the food store, ride in a coat pocket, and occupy an unattended hat in the same afternoon.

Field Guide · Uninvited Locals

Pests

Small native animals that support the ecosystem while testing every storage solution humans invent.

2 entriesSeed dispersalProperty damage
Stripeback Squirrel
Seed Disperser and Pest

Stripeback Squirrel

Length
About 18–25 cm
Weight
About 200–500 g
Glow
Tail tip, dorsal stripes, or both

Field note: Ecologically useful. Logistically infuriating.

A miniature climber that thrives in warm, food-rich settlements and enters spaces larger animals cannot.

Length
About 12–20 cm
Weight
About 15–60 g

Field Guide · Beyond the Fence

Wildlife

Aquatic food webs, large predators, and native insect-control species outside domesticated life.

3 entriesAquaticsPredators
Cave Fish & Aquatics
Aquatic Wildlife and Food Source

Cave Fish & Aquatics

Underground rivers and lakes support fish, crustaceans, and other aquatic life central to riverside nutrition.

Habitat
Underground rivers and lakes
Value
Food and local fishing economies

Depends on water chemistry and the Mineral Web

Field note: Not every river supports useful fishing. Water chemistry decides whether a channel is a pantry or merely wet.

Smilodon
Large Wild Predator

Smilodon

A powerful ambush predator left alone while hunting wild prey, but managed aggressively after repeated livestock conflict.

Conflict
Livestock predation
Glow
Controlled facial, shoulder, spine, and flank marks
Response
Deterrence first, removal when necessary

Field note: Admired, feared, and granted much less philosophical consideration near the herd routes.

Numbat
Insectivorous Wildlife

Numbat

A gentle native mammal that regulates insects and is welcomed around farms and settlement edges.

Body
About 25–47 cm
Weight
About 300–700 g
Glow
Dorsal stripes, tail, face, and limbs

Field note: Small, gentle, glowing, and eats bugs. An undefeated public-relations strategy.

Field Guide · Living Light

Bioluminescence

The Range reads light as biology, behavior, identity, and warning rather than simple decoration.

Prey lightPredator lightEcological signals

The Origin of Living Light

Mineral-Web microbes support luminous fungi, plants, and invertebrates. Dietary exposure and biological incorporation carried that light into larger animals, while predators evolved more controlled forms.

Prey Light

Herbivores and herd animals tend to glow continuously. Their markings support herd recognition, parent-and-young tracking, mate signaling, warning displays, and individual identification.

Predator Light

Predatory species tend to control their glow. Dimming aids stalking, while flashes and pulses support pack communication, courtship, territorial display, and intimidation.

Juvenile Light

Young animals may be brighter or patterned differently, making them easier for parents and herd members to track through darkness and crowded grazing chambers.

Biological Fingerprints

Individual glow patterns can identify livestock and working animals at distance. Handlers learn familiar crest lines, flank constellations, tail rings, and facial marks.

Ecological Signals

Unusual brightening or dimming can accompany mineral bloom, chemical change, stress, predator activity, temperature shifts, disease, water changes, or broader disturbance.

Still Unmeasured

Dilophosaurus, Parasaurolophus, Sailrunner, Triceratops, Guanaco, Dodo, Dire Wolf, Tilcayo, Cave Fish and Aquatics, and Smilodon do not currently have complete numerical measurements in their source profiles. Their visual scale should remain illustrative until canon values are added.
