The Host of the Unforgiven Dead
The Sluagh are the restless dead — specifically the sinful dead, those who died without being properly sent on, without the rites that would have settled them. They move through the night sky in vast flocks, like a murmuration of starlings but larger and darker, and they always come from the west.
The west matters. In the old Irish world the Otherworld lay to the west — out across the Atlantic, in the islands beyond the sea where the Tuatha Dé Danann went, where Manannán mac Lir ruled. The dead were supposed to travel west. The Sluagh are the dead who did not make it, who could not rest, who now move through the sky in the direction they should have gone.
They come for the dying. They enter houses through west-facing windows to take a soul before the natural death can complete — intercepting it, adding it to their own number. Families in the west of Ireland and the Scottish Highlands kept west-facing windows closed when someone in the house was dying. They kept watch around the bed. A dying person alone at night with the west window open was considered to be in genuine danger.
In some accounts the Sluagh also took the living — forcing a person outside, making them ride with the host through the night sky, sometimes dropping them from a great height when the flight was over.
