Deity Name: Aelthrys, Keeper of the Deep and Shaper of Shores
Lore
The Tidebound Covenant teaches that Aelthrys is the living breath between water and land, the boundary and the bridge, the shaper of coasts, the mover of fish, the sculptor of ice, and the breaker of ships when promises are betrayed. In the oldest stories, Aelthrys was neither born nor made, but simply rose from the union of moonlight and saltwater, carrying in their hands the first conch-horn whose note called the tides. They taught the first fisherfolk how to read the hidden currents beneath the waves and how to sculpt tools from ice so cold that it cut without melting. Those who honored the seasons of the sea were given bounty and calm passage. Those who fished without balance, took without offering, or ignored the moon’s rhythm would find their nets torn, their harbors frozen, and their sails caught in unending calms.
The Tidebound Covenant claims that the ocean is not a place, but a living memory of Aelthrys, and every wave carries their will. The coastline of Stillbay is seen as the deity’s ever-changing script, rewritten with each tide to remind mortals that permanence is an illusion.
Personality
Aelthrys is portrayed as patient but unyielding, capable of nurturing with limitless generosity or destroying with precise cruelty. They are neutral but deeply invested in maintaining equilibrium between abundance and restraint. They rarely intervene directly, preferring to weave fate through wind, water, and the slow grind of ice.

• Promotes cooperation between merchants, fisherfolk, and naval crews through shared rituals.
• Enhances magical affinity for tidal, current, and weather-based spells.
• Reinforces cultural identity through seaborne festivals and sacred voyages.
Negatives:
• Insularity toward foreign maritime religions and distrust of landlocked cultures.
• Overreliance on maritime-based omens can cause delays or misjudgments in trade and defense.
• Strict observance of sea-related taboos sometimes conflicts with practical governance or military needs.
• Some sects interpret the deity’s will in contradictory ways, causing disputes between rival ports.
Type of Temple:
• Open-water sanctuaries built on anchored platforms or large coastal stone rings, always aligned with the prevailing tide.
• Inner chambers designed like inverted hulls with shell-inlaid altars, lantern braziers, and tidal pools for sacred water rites.
True Followers:
• Estimated 77,550,000 fully dedicated practitioners (slightly over half the island’s population), with a further 20% showing partial observance.
What They Do:
• Perform daily “Tide Greetings” at sunrise and sunset, offering saltwater to the deity’s altar.
• Engage in monthly Full Current Festivals where offerings of shellwork, woven kelp, and salt-cured fish are cast into the sea.
• Maintain and protect sacred shipping lanes deemed blessed by the deity.
• Appoint “Wave-Keepers,” temple-trained navigators who guide important vessels during treacherous weather.
• Mediate disputes involving fishing rights, harbor tolls, or shipwreck salvage under divine authority.
Believers’ Beliefs:
Followers hold that the deity embodies the eternal pulse of tide and current, guiding all life as water shapes the land. They believe every living being is a “drift vessel” carried by the Great Current, and that obedience to its flow ensures fortune, safe passage, and a legacy unbroken by storms. The ocean is viewed not as a mere resource but as the living body of the divine, and harming it without cause is sacrilege. Believers see shipwrecks and drownings not as tragedies, but as the deity reclaiming vessels into the hidden harbors of the deep.
Regular Services:
Services are held at dawn and dusk, timed to the turning of the tides. At dawn, congregants face the sea, releasing small crafted offerings (driftwood carvings, shell tokens, woven kelp charms) into the water while chanting in Vhallic rhythm to mimic wave patterns. Dusk services are quieter, marked by lanterns set afloat on shallow tides, representing safe guidance home for voyagers and spirits. Priests lead tide-measure rituals, read signs from wave behavior, and pour consecrated saltwater over the foreheads of the faithful as a blessing for health, trade, and safe travel. Large gatherings during equinoxes involve entire fleets anchored offshore in vast floating circles for mass rites.
Funeral Rites:
The deceased are shrouded in tide-marked cloth and laid upon a ritual raft. Family members and community gather to inscribe the raft’s boards with blessings, prayers, and depictions of the departed’s life at sea or on shore. The raft is set adrift during high tide, accompanied by chants and drum rhythms mimicking the heartbeat of the ocean. If recovered later by chance, the raft is disassembled and its pieces added to the foundations of temple piers, symbolically merging the soul with the deity’s sacred harbors. Those who die inland are cremated, their ashes mixed with salt and scattered into the waves at the next festival tide.

The god of the Stillbay faith, Aelthuun the Tide-Bearer, grants magic that mirrors the interplay of currents, waves, and stonebound shorelines, allowing both defensive and offensive use depending on how the avatar channels the deity’s granted favor through appropriate gear and trained skills.
Defensive Use
• Waveward Shroud – Summons a rolling wall of salt-laced water, hardened with suspended sediment and shells, that can blunt physical blows and deflect projectiles.
• Anchor’s Resolve – A blessing that fixes the avatar’s stance like a reef, making it nearly impossible to be moved by force, wind, or wave for the duration.
• Mist of the Lost Shoals – Conjures a drifting salt-fog charged with faint phosphorescence, obscuring sight and confusing magical tracking.
• Undertow Warding – Creates a current beneath an area that drags away incoming attacks that strike the ground or floor, reducing area-effect harm.
• Coral Mend – Rapidly calcifies and seals breaches in armor or structures, forming a hard barrier against further strikes.
Offensive Use
• Tidebreaker Surge – Projects a focused wall of water mixed with heavy grit to knock foes off balance, erode footing, and cause blunt trauma.
• Razor Shoal – Summons shards of magically-hardened shell and coral that sweep outward in a wave, slicing through exposed flesh and light armor.
• Crush of the Deep – Mimics the crushing pressure of ocean depths, momentarily slowing enemies’ movements and impairing breathing.
• Rip Current Pull – Creates an invisible drag through air or water, pulling foes into confined areas or toward prepared strikes.
• Gull’s Claim – Channels flocks of spectral sea-birds to dive, peck, and harry opponents, disrupting chants, aim, and coordination.
Song of Stone and Tides
It is told, though perhaps told from the telling of those before, that in the age before the bright shells grew upon the sea’s lip, there was no Stillbay, no calm harbors, no walls of tide and rock. Only the Endless Water, and in its belly the sleeping current that was Aelthuun, unknown to mortals and uncalled by any name.
Then came the People of No Shore, drifting upon skins of air and reed, their feet raw from the salt and their eyes dim from the glare. They knew not land, for none had seen it. They had only the hunger that gnaws and the thirst that betrays, and they sang in their small voices to the nothingness. It is said their song reached down into the deeps where Aelthuun lay curled among anchors of stone not yet lifted from the ocean floor. The god heard not words, but the pulse of need.
From the god’s breast rose the First Swell, a tide that lifted the People of No Shore and bore them without oar or wind. For nine turnings of the moon they drifted on the swell, and in its guiding was no star to chart, yet they were carried as a gull’s feather upon breath. At the tenth turning, they saw the Back of the Great Whale—no beast, but a ridge of stone rising from the waves. Here the swell broke, and the people’s reed craft splintered upon sharp stone, but none were lost, for the god’s hands were in the water, placing them gently upon the new shore.
It was a place of ice and flint, where the wind cut like the teeth of unseen fish. They knew not how to walk upon the frozen crust or take fish from beneath its shield, and many looked to the water with longing, to drift away. But the god’s whisper came in the sound of the breaking ice: “Stone is the root, tide is the breath—bind both, and live.”
So the people learned to strike stone against stone until the edge was keen. They learned to shape the frozen water into walls against the wind, and to set lines in the tide’s turning to take fish and shell. But always they left the First Shape—a great curved wall of ice and stone at the water’s lip—untouched, for it was said that was the place where Aelthuun first stepped from water to greet them.
One year the winter did not break. The ice grew thick as the god’s own shell, and the fish were gone, and the children’s breath grew shallow. The People of No Shore, now called the Bayfolk, gathered at the First Shape and sang the old song that had brought the god before. But the sea lay still, and their voices cracked. In despair they took the Great Net—woven from hair, reed, and sinew—and cast it into the water, hoping to catch the god’s favor.
What they drew up was no fish, but a heart of coral, glowing with the deep’s fire. They knew to carry it to the First Shape and lay it there, but in their hunger they argued: one said to grind it for food, another to burn it for warmth, and another to sell its light for tools. While they quarreled, the tide rose without wind, and from it came a form half-wave, half-stone, bearing eyes like polished shells. Aelthuun spoke in a voice like grinding ice: “The heart of the sea is not to feed the belly nor light the hearth. It is the anchor to bind you when the winds of want pull you apart.”
Then the god struck the heart with a single wave. It shattered into a thousand shards, each lodging in the chest of a Bayfolk. From that day, they could feel the pull of each other across water and ice. They no longer quarreled in times of hunger, for each knew the hurt of the other, and each storm that came was met with hands and walls joined together.
Yet the god’s gift had price. When the tide called for defense, they were bound to rise; when the tide called for strike, they were bound to go. And in the years after, whenever a Bayfolk was taken by the deep, the others would feel the shard grow cold, and they would lay the body within the First Shape so the god might take back what was given.
The story says the First Shape still stands, though the ice has melted and formed again a thousand times. Pilgrims walk the shore with bare feet to feel the pull of the shards in the sand, and the ruling line of Stillbay claims descent from those first placed upon the Back of the Great Whale. And in the storms of war or hunger, the tide’s wall rises still, shaped by unseen hands, to shield the bay’s heart.
Moral: The strength of the tide is not in its rise or fall, but in the way it binds the stones together.
