In Celtic folklore the Wirry-Carle or Wirry- Cowe are a malevolent fae spirit that serves much the same purpose as bugbears and goblins in Northern Europe . As such there is little definitive information about these creatures as they morph to become whatever the teller of a tale needs them to be.
In Eira however …
… The Wirry-Carle are a race of barbaric demi-humans who make their home in the highlands of Eira and in the barrowlands of the western coast. They are slim, emaciated looking creatures standing approximately 5 feet tall, with stooped, backs and long clawed hands. They see all other races as enemies but rarely do more than village raids and caravan ambushes.
Wirry-Carle are a vicious race who believe that they were once as beautiful as the Au-Sidhe until they were tricked by the Night Queen of the Un-Sidhe and cursed with their horrid forms. They hold an extraordinary hatred of Au-Sidhe, Un-Sidhe and any with even a hint of Sidhe blood.
