The Rinn — Sea Life of Athernyx
CANON — All Ocean Creatures
What Rinn Are
Rinn is the Alkin word for all sea creatures. Fish, eels, shellfish, the things in the deep — all Rinn.
On a world that's 97% water, the ocean isn't a feature. It's the default. The sea teems with life while the land stays quiet. Coastal villages survive on Rinn. Inland settlements trade for it.
The Network reaches into coastal shallows, but the open ocean has its own rules. And The Deep? The Network doesn't go there. Something else does.
Ocean Zones
| Zone | Depth | Light | Character |
|---|---|---|---|
| Shallows | Coastal, reefs | Full sun | Villages fish here. Familiar. Food. |
| Open Blue | Pelagic, surface | Daylight | Sailors' domain. Migrations. Larger Rinn. |
| Sky-Swimmers | Surface + air | Full sun | Rinn that learned to fly. Bridge two worlds. |
| Twilight | Mid-depth | Dim, fading | Things get strange. Bioluminescence. |
| The Deep | Abyssal | None | Unknown. Stories. The Ather bleeds through. |
The Shallows
What villages fish. What markets sell. What everyone eats.
Common Catch
| Name | Analog | Size | Notes |
|---|---|---|---|
| Silvergill | Sardine/Herring | Small, schools | The staple. Smoked, salted, fried. Every coastal village lives on these. |
| Coppermouth | Bass | Medium | Firm white flesh. The "good fish" for meals. |
| Duskfin | Mackerel | Medium | Oily, rich. Grilled whole. Keeps well smoked. |
| Mossback | Flounder | Flat, medium | Bottom-dweller. Mild taste. Pan-fried in butter. |
| Reefrunner | Snapper | Medium | Bright scales, sweet meat. Prized catch. |
| Thornhead | Scorpionfish | Small-medium | Ugly but delicious. Spines removed, meat is tender. |
| Bluescale | Trout | Medium | Found where rivers meet sea. Delicate flavor. |
| Lanternjaw | Anglerfish | Small-medium | Shallow-water variety. Lure glows faint green. Meat is dense. |
Shellfish
| Name | Analog | Notes |
|---|---|---|
| Clickclaws | Crab | Most common. Boiled, cracked, eaten with bread. |
| Stoneshell | Lobster | Larger, deeper water. Celebration food. |
| Razorbacks | Shrimp | Abundant. Dried, fried, or in stews. |
| Inkpots | Mussels | Cluster on rocks. Steamed open. Cheap protein. |
| Spireshells | Conch | Large spiral shells. Meat is chewy, flavorful. Shells kept as horns. |
| Pearljaws | Oyster | Raw or cooked. Occasionally contain actual pearls. |
| Sandburrowers | Clams | Dig them at low tide. Sweet, briny. |
Coastal Eels
| Name | Size | Notes |
|---|---|---|
| Ribboneel | 1-2 meters | Common. Slippery, fast. Smoked eel is a delicacy. |
| Moray Rinn | 1-3 meters | Hides in reef crevices. Territorial. Bite is nasty but meat is good. |
Open Blue
What sailors see. What migrates. What hunts.
Schooling Fish
| Name | Analog | Size | Notes |
|---|---|---|---|
| Shimmerscale | Tuna | Large | Migratory schools. Fast, powerful. Premium meat. |
| Ironside | Swordfish | Large | Solitary hunter. Dense flesh. Trophy catch. |
| Stormrunner | Mahi-mahi | Medium-large | Follows ships. Bright colors fade after death. |
| Wavebacks | Dolphins | Medium | NOT fish — but Alkin call them Rinn anyway. Intelligent, playful. Never eaten. |
Ocean Hunters
| Name | Analog | Size | Danger | Notes |
|---|---|---|---|---|
| Glassfin | Reef shark | 2-3m | Low | Curious, not aggressive. Follows boats for scraps. |
| Blacktooth | Bull shark | 3-4m | Medium | Territorial. Will bump boats. Coastal threat. |
| Silenthunter | Great white | 5-7m | High | Rare. Respected. Sailors give it wide berth. |
| Razormouth | Barracuda | 1-2m | Medium | Lightning fast. Attacks shiny objects. |
| Hammerskull | Hammerhead | 4-5m | Low | Strange shape. Hunts rays and bottom-dwellers. |
Gentle Giants
| Name | Analog | Size | Notes |
|---|---|---|---|
| Driftwhale | Whale | Massive (15-25m) | Filter feeders. Sing deep songs. Sacred to coastal folk. |
| Sailback | Whale shark | Huge (10-15m) | Spotted pattern. Harmless. Good omen to swim near one. |
| Shellmound | Sea turtle | Large (2-3m) | Ancient-looking. Shells sometimes grow small ecosystems. Protected — bad luck to harm. |
Sky-Swimmers
Rinn that learned to fly. Bridge the sea and sky.
Sea-Sky Rinn (Coastal, Brief Flights)
| Name | Size | Notes |
|---|---|---|
| Bellcriers | Small (15-30cm) | Amphibious scavengers with inflatable throat sacs. Perch in groups on dock posts, rooftops, cargo cranes — anywhere near fish. Fin-wings allow short gliding hops between perches. Webbed feet grip wood and stone. Their resonant chorus is the soundtrack of every port city. Dockworkers don't hear them anymore. Travelers never forget them. |
| Driftfins | Small (20-40cm) | Schools burst from waves, catch light like prisms, splash back. Never far from water. |
| Skimmers | Medium (40-80cm) | Solo hunters. So fast and low they blur swimming and flying. Where Skimmers hunt, fish are plentiful. |
Sky Rinn (Mana-Sustained, Cross Over Land)
| Name | Size | Notes |
|---|---|---|
| Veilrays | Large (2-3m wingspan) | Like manta rays crossed with kites. Absorb mana through membrane wings. Glide for hours over land. Glow at dusk. Majestic. Never hunted. |
| Crestfloaters | Variable (30cm body, 2m tendrils) | Jellyfish-like. Float on lighter-than-air gas from metabolizing mana. Wind-carried anywhere. Tendrils sting. Considered sacred. |
Sky-Swimmer Omens
| Behavior | Meaning |
|---|---|
| Bellcriers going silent | Danger nearby — they sense vibrations through the docks |
| Driftfins schooling | Fish are running — good catch coming |
| Veilrays at sunset | Peaceful night ahead |
| Skimmers racing inland | Storm coming — they're heading to shelter |
| Crestfloaters descending | Weather changing — pressure shift |
Sayings:
- "Bellcriers quiet? Watch your back."
- "Veilray sky, sleep well tonight."
- "Skimmers running? Tie down your boats."
- "Count the Crestfloaters, know the wind."
Twilight Zone
Where light fades. Where things get strange.
Bioluminescent Rinn
| Name | Analog | Notes |
|---|---|---|
| Ghostfin | Hatchetfish | Flat, silver. Belly glows to hide shadow from below. Eerie. |
| Sparkswarm | Lanternfish | Tiny, countless. Whole clouds of blinking lights in the mid-depths. Rise at night to feed. |
| Luremother | Anglerfish (deep) | Large. Dangling light attracts prey. Face like a nightmare. Rarely seen. |
| Veinfish | Dragonfish | Long, thin. Glowing lines run full length. Needle teeth. |
| Membranes | Jellyfish | Pulsing bells of light. Some small, some massive. Drift in curtains. |
Twilight Hunters
| Name | Analog | Size | Notes |
|---|---|---|---|
| Gulper | Gulper eel | 1-2m | Massive hinged jaw. Swallows prey whole. Looks like a swimming mouth. |
| Shadowfin | Thresher shark | 4-5m | Long tail fin. Hunts by stunning prey. Moves between depths. |
| Glasseye | Giant squid | 3-8m | Huge eyes catch faintest light. Tentacles snatch from darkness. Intelligent. |
The Deep
Where the Network doesn't reach. Where the Ather bleeds through.
No one fishes The Deep. What comes up in nets dropped too far is... wrong. Translucent. Glowing in ways that hurt to look at. Sometimes still moving days after death.
Sailors have names for what they've glimpsed. Whether these are real creatures or fever dreams, no one can say.
The Named Ones
| Name | Description | Status |
|---|---|---|
| The Maw | A mouth. Just a mouth. Miles wide. Ships that sail over it at night see light far below — like dawn coming from the wrong direction. Then the light rises. | Legend. Maybe. |
| Driftking | Colossal jellyfish. Bell the size of a ship. Tendrils trail for hundreds of meters. Glows in colors that don't exist on land. Surfaces once a generation. | Confirmed sightings. Rare. |
| Threadworms | Kilometers-long things like living rope. Bioluminescent. Seen from ship decks, pulsing in patterns that almost look like language. | Seen often. Never caught. |
| The Sleepers | Vast shapes on the ocean floor. Detected by how currents move around them. Never seen directly. Might be geological. Might not be. | Unknown. |
| Atherborn | Rinn that look like spirits — translucent, particle-woven, barely solid. As if something from the Ather tried to become a fish and almost succeeded. | Confirmed. Nets sometimes catch them. They dissolve within hours. |
Deep Rinn Rules
- What lives in The Deep is not fully of this world
- The Ather reaches the ocean floor where the Network can't
- Deep Rinn sometimes surface during strange tides or mana surges
- Eating Deep Rinn meat is taboo — no one knows what it does to you
Cephalopods
The clever ones. Found at all depths.
| Name | Analog | Zone | Notes |
|---|---|---|---|
| Inkspitter | Cuttlefish | Shallows | Color-shifting. Fishers catch them for ink (alchemy) and meat. |
| Rocktopus | Octopus | Shallows/Reef | Eight-armed problem solvers. Escape any trap once. Delicious. |
| Glasseye | Giant squid | Twilight | Listed above. Intelligent. Dangerous. |
| Kraken | Colossal squid | Deep | 20+ meters. Arms like ship masts. Will attack vessels. Rare but real. |
Eels (All Zones)
| Name | Zone | Size | Notes |
|---|---|---|---|
| Ribboneel | Shallows | 1-2m | Common. Smoked eel is a delicacy. |
| Moray Rinn | Shallows/Reef | 1-3m | Territorial. Reef crevices. Nasty bite. |

The Rinn-Kin — Those Who Walked Ashore
Not all Spirits that crossed from the ocean-side of the Ather became Rinn. Four adapted to land while keeping the ocean inside them. These are the Legendary Mana'mals — creatures with Rinn heritage walking through forests that have never seen the tide.
| Name | Kind | Signature |
|---|---|---|
| Duskpuff | Furred | Shadow creature — inflates with rainbow bioluminescent burst when startled |
| Frilldrift | Winged | Flowing cerata-wings, toxic, impossibly colorful, drifts rather than flies |
| Prismstrike | Plated | Full mana-spectrum vision, iridescent segmented armor, primordial patience |
| Coilguard | Scaled | Armored plates, upright posture, prehensile tail, male carries young |
They carry ocean engineering in land bodies — bioluminescence, hydraulic mechanisms, armor plating, toxic chemistry. The Network registers them as slightly wrong. Like a word pronounced with a dialect from across the sea.
