Bestiary Wind Serpent Type: Flying predator / bondable mount Size: 20-40 meters long Behavior: Hunts in twilight belt thermal updrafts. Intelligent, territorial, capable of complex communication. Bonded serpents serve as mounts, messengers, and protectors. Abilities: Flight (sustained by wind currents) Thermal vision Pack tactics Psychic receptivity (bonding) Vulnerabilities: Exposed underbelly (soft tissue) Grounded in windless zones Bonding disruption causes disorientation Encounter Notes: Unbonded serpents attack threats to territory. Bonded serpents defer to Beastwalker. Juveniles are playful but dangerous. Elders possess near-human intelligence. Thermal Lizard Type: Ambush predator Size: 2-4 meters long Behavior: Heat-seeking, camouflaged in day-side margins and ruins. Waits motionless for hours before striking. Solitary except during mating. Abilities: Thermal camouflage (blends with heat signatures) Explosive speed (short bursts) Thermal vision Armor-plated scales Vulnerabilities: Cold exposure (sluggish below 10°C) Poor low-light vision Predictable attack patterns Encounter Notes: Often found near geothermal vents or day-side salvage sites. Can be detected by thermal sensitives as "cold spots" against warm backgrounds. Shadow Stalker Type: Apex predator (night side) Size: 3-5 meters tall (bipedal) Behavior: Hunts by sound in absolute darkness. Nearly invisible. Territorial. Avoids light instinctively. Abilities: Perfect night camouflage Echolocation Razor claws and fangs Silent movement Vulnerabilities: Light sources (causes disorientation) Loud noises (disrupts echolocation) Slow in open areas Encounter Notes: Primary threat in Deep Roads and night-side caves. Deepkin use resonance to detect them. Carry bioluminescent markers always. Glowworm Swarm Type: Bioluminescent cave-dweller Size: Individual: 10-20 cm; swarm: thousands Behavior: Filter-feeds on airborne spores. Harmless individually, overwhelming in swarms. Light pulses disorient predators. Abilities: Bioluminescence (controllable intensity) Synchronized light pulses (hypnotic) Numbers (crush threats by mass) Vulnerabilities: Smoke (disperses swarm) Sound (disrupts coordination) Cold (induces hibernation) Encounter Notes: Beautiful but dangerous in large numbers. Deepkin harvest them for lighting. Swarms indicate nearby food sources (fungal blooms). Sand Skimmer Type: Burrowing scavenger (day side) Size: 1-2 meters long Behavior: Burrows through superheated sand. Attracted to movement. Scavenges equipment, corpses, and mining waste. Cowardly but persistent. Abilities: Sand-swimming (burrows rapidly) Heat resistance (tolerates 500°C+) Vibration sense Corrosive saliva (melts metal) Vulnerabilities: Sonic weapons (disrupt burrowing) Extreme cold (immobilizes) Predictable (always approaches from downwind) Encounter Notes: Nuisance near day-side operations. Can be lured with bait. Salvaged equipment often shows skimmer damage. Feral Bonded Creature Type: Former Beastwalker mount (any species) Behavior: Psychic bond broken by trauma, death, or sabotage. Retains training but acts unpredictably. Dangerous because it understands human tactics. Abilities: Species-dependent (wind serpent, thermal lizard, etc.) Human tactical knowledge Psychic resistance (rejects new bonding attempts) Vulnerabilities: Species-dependent Psychic trauma (erratic, exploitable) Encounter Notes: Often hunts former handlers. Deepkin see ferals as tragic. Wind-Kin attempt rehabilitation. Most must be put down. Storm Beetle Type: Flying insect / swarm Size: Individual: 5-10 cm; swarm: thousands Behavior: Native to twilight belt storm fronts. Feed on electrical discharge during superstorms. Harmless individually, dangerous in swarms when they discharge stored energy. Abilities: Flight (sustained by storm winds) Electrical discharge (coordinated swarm attack) Storm prediction (appear hours before major weather) Chitinous armor (resistant to wind damage) Vulnerabilities: Grounded in windless conditions Cold (induces torpor) Electromagnetic interference (disrupts coordination) Encounter Notes: Weatherworkers use them as early warning system. Some settlements harvest their electrical organs for batteries. Swarms occasionally discharge into metal structures, causing fires. Crevice Eel Type: Burrowing predator Size: 3-6 meters long Behavior: Lives in Deep Roads and twilight belt crevices. Ambushes prey by erupting from stone. Excellent tremor sense. Solitary and territorial. Abilities: Stone-boring (creates new tunnels) Tremor sense (detects movement through rock) Crushing bite (armored jaws) Slime secretion (acidic, aids tunneling) Vulnerabilities: Sonic weapons (disorients tremor sense) Predictable (always attacks from below) Slow outside tunnels Encounter Notes: Major threat in Deep Roads. Deepkin map known eel territories. Leave tremor-dampening markers to avoid attracting them. Slime is valuable for industrial applications. Frost Moth Type: Night-side herbivore Size: Wingspan: 30-50 cm Behavior: Gentle creature that feeds on ice crystals and lichen. Beautiful bioluminescent wings. Used by Deepkin as light sources and companions. Abilities: Bioluminescence (controllable, multiple colors) Cold resistance (thrives in -100°C) Pheromone communication Ice crystal digestion Vulnerabilities: Heat (dies above 20°C) Fragile wings (easily damaged) Predictable (drawn to lichen blooms) Encounter Notes: Domesticated by night-side communities. Wings used for decorative purposes and ceremonial garments. Wild migrations signal seasonal ice shifts. Poaching is illegal in most settlements. Thermal Bloom Type: Plant / ambulatory organism Size: 1-2 meters diameter Behavior: Semi-mobile plant that migrates toward heat sources. Roots can detach and re-establish. Absorbs thermal energy for sustenance. Neither predator nor prey—environmental hazard. Abilities: Thermal absorption (cools surroundings) Slow mobility (roots as limbs) Heat tracking Spore release (irritating to lungs) Vulnerabilities: Cold (enters dormancy) Fire (destroys rapidly) Dehydration Encounter Notes: Found near geothermal vents and day-side margins. Can cool settlement heating systems if not removed. Farmers use them to regulate greenhouse temperatures. Spores are medical ingredient (anti-inflammatory).
