Eldritch Rocky Shore

Something from outside the world has touched this land. Angles are wrong, the stars sit in the wrong places, and the animals that remain have too many eyes or too few. Those who stay too long start to hear a voice under every other sound. Rocks, cliffs and tide pools battered by the sea. Seals and seabirds crowd the ledges, shellfish cling to the stones, and the tide decides when a way along the foot of the cliff is open.

Hazards

Tides. The sea comes back faster than a walker on the flats. A causeway or a beach crossed at low tide can close behind the party.
Falling rock. Frost, rain or a careless step bring stones down from above. Scree slides underfoot.
Wrong angles. Paths bend back on themselves and distances will not hold. A ridge seen at noon is no closer by evening.
Whispers from beyond. At night a voice speaks just below hearing, in a language no one ever learned and everyone almost understands.
The glimpse. Sometimes, at the edge of the light, something shows itself for a heartbeat: too large, too many limbs, gone at once.

D&D 5e

Plays as: coastal, normal pace at most
Checks: forage: Survival DC 10 · find the way: DC 5 · search: DC 15

Wrong angles. (House rule) Each day the guide makes a DC 14 Wisdom (Survival) check. On a failure the party covers only half the day’s distance, however long it walks.
Whispers from beyond. A creature that keeps watch alone makes a DC 15 Wisdom save, taking 3d6 Psychic damage on a failure, or half as much on a success.
The glimpse. Whoever sees it makes a DC 15 Wisdom save or is Frightened, repeating the save at the end of each of its turns.

Falling rock. An avalanche, landslide or collapse deals major or massive bludgeoning damage (8d6 to 24d6); a Reflex success halves it and a critical success also avoids burial. Buried creatures take minor damage each minute and are dug out with Athletics (GM Core p. 96).

Adventure hooks

A surveyor hired to map the land keeps drawing paths that close on themselves in fewer steps than it took to walk them. His guild thinks he drinks, and he wants a sober witness who can count to sign his maps.
A shepherd’s daughter has begun answering questions a moment before anyone asks them, and her mother begs the party to cure her before the priest hears of it. The girl is not possessed: she is translating the voice under every sound, and all it asks is to be left alone.
A scholar from the city pays a silver piece to anyone who can hum him the voice beneath the sounds. By now the whole tavern hums the same tune without noticing, and the scholar has stopped humming it, which frightens him far more.
A hunting party came back with one man more than it left with. Each hunter swears he knows the newcomer, and each names a different person; he is kind, helpful and tireless, and nobody has ever seen him blink.
Wreckers light false fires on the cliffs on stormy nights to draw ships onto the rocks. A young wrecker wants out, since he found his own brother’s sea chest among the spoils.
Egg gatherers go down the cliffs on ropes each spring to rob the seabird ledges. One man’s rope was cut, and he lived two days on a ledge before anyone heard him; he saw who did it, and will not say.
A grey seal comes into the cove every evening and stares at one house. The widow who lives there asks the party to find out what it wants; she thinks she already knows.
A spring tide has opened the way along the foot of the cliffs to a cove cut off the rest of the year. A smuggler pays well for a cargo carried through and back, and the tide turns in four hours.
