The Sluagh Roads of the West
The Unforgiven Dead, the Fairy Mounds, and the Thin Places Where Ireland's Living and Dead Have Always Traveled Together
In the western parishes of Ireland, where the Atlantic wind never quite stops and the fairy mounds (si) rise from the bog landscape with the permanence of the land's oldest memory, the boundaries between the world of the living and the world of the dead are negotiated rather than fixed. The Sluagh -- the restless dead who fly on the western wind -- are the most feared of Ireland's supernatural forces: the unforgiven dead who travel in host formations and drag souls away at night. The players are Sluagh hunters: ordinary people from the western parishes who have developed the knowledge and tools to drive the host away, protect the vulnerable, and occasionally find out what specific Sluagh want -- because sometimes the Sluagh are trying to communicate something the living have refused to hear.
“The Sluagh don’t come for people at random. That’s what they say in the east, where they don’t know. Out here we know different. The Sluagh come for the unfinished. They can smell it: the apology that was never given, the thing that was left undone, the grief that was never let out. They don’t come because you’re a sinner. They come because you’re unresolved. I’ve seen very good people taken and very bad ones left completely alone, and the difference was always the same.”

1. Setting Overview & Tone
High-Concept Pitch: The dead that haunt Ireland’s west aren’t all dangerous. Some of them are just unheard.
The setting draws on Irish folklore traditions that are deeply intertwined with the landscape itself: the si (fairy mounds, many of which are real Neolithic structures), the concept of thin places where the boundary between worlds is negotiable, the Sluagh (host of the unforgiven dead, distinct from other Irish fairy traditions), and the banshee as a family-specific death omen rather than a generic death spirit.
This is not high fantasy Ireland. This is the Ireland of the Atlantic shore: rain, bog, stone walls, small communities, the intimacy of a population that has known each other for generations, and the supernatural that lives in the landscape alongside them as something to be managed rather than defeated.
Sensory Pillars:
- Sight: The western Irish landscape in its full atmospheric reality: bog and stone and low cloud, the Atlantic visible from high ground, fairy mounds rising from the landscape with no explanation that satisfies the inquiring mind, the narrow roads between hedges that could be anywhere and are exactly here, and at night, on the western wind, the darkness that moves against the wind and the shapes within it.
- Sound: The Atlantic wind that never stops and that experienced locals read the way others read weather; the banshee’s keening (each family’s banshee has a distinctive voice, recognized by those who’ve heard it before); the absence of sound that precedes a Sluagh passing, which animals notice first; and the quietness of a community that has learned what not to speak about after dark.
- Touch & Smell: The bone-deep damp of Atlantic Ireland, the smell of peat smoke from every chimney, the cold stone of a fairy mound that is always cold regardless of weather, and the specific quality of night air on the western roads that those who walk them late learn to pay close attention to.

2. The Western Supernatural Landscape
The Si (Fairy Mounds)
Ancient mounds, many of genuine Neolithic origin, that serve as points of contact with the otherworld. They should not be disturbed. They are disturbed regularly, either by ignorance or desperation. The consequences are community matters.
The Sluagh Host
The unforgiven dead flying in formation on the western wind, moving between dusk and dawn, capable of pulling souls from sleeping or sick people. They are real and they are dangerous. They are also, investigation often reveals, organized around specific purposes that the living world has refused to acknowledge.
The Banshee
Not generic. Each old family has their own banshee, a specific spirit attached to that bloodline. The banshee’s keening announces family deaths. Banshees are not malicious — they are grieving. Their grief is real and it is for the family they serve.
The Thin Places
Certain locations where the boundary between worlds is not a wall but a membrane: crossroads at certain times, water-edges, the summit of certain hills, the interior of the si. At these places, communication between living and dead is easier, which creates both opportunity and danger.

3. Adventure Seeds
-
The Host’s Message: The Sluagh host has been circling a specific farmhouse for three nights without taking anyone. This is unusual — the host either takes or passes on. Investigation reveals the host is organized around a specific unresolved situation involving the farmhouse family and a dead member who has a message that cannot be delivered through normal channels.
-
The Disturbed Mound: Construction work has disturbed a si. The community is experiencing consequences. Finding out what was disturbed, negotiating with what was disturbed, and addressing the consequences before they escalate is complicated by the fact that nobody will officially acknowledge the si was involved.
-
The Family Banshee’s Silence: A prominent family’s banshee has gone silent. This is deeply alarming: either the family line is ending without the usual warning, or something has happened to the banshee. Both possibilities require urgent investigation. The family is in denial about needing help.
-
The Thin Place Collapse: One of the known thin places has become permanently open: not just accessible at certain times but continuous. The living world and the otherworld are bleeding into each other at this point. People near it are experiencing temporal confusion. The dead near it are visible in daylight. This requires resolution before it spreads.
-
The Taken: A community member was taken by the Sluagh three nights ago and is not dead: they’re trapped between the worlds, visible to the living but unable to return. Getting them back requires finding the specific Sluagh who took them, understanding what they wanted, and negotiating a return before the person fully joins the host.
