At the end of which season the daughters of Airitech would come out of the Cave of Cruachan every year?
Cas Corach In Irish mythology, Cas Corach was a hero who helped Caílte mac Rónáin kill three werewolf-like creatures, the daughters of Airitech who would come out of the Cave of Cruachan every year around Samhain and destroy sheep. The she-wolves liked music, so he aided in their slaying by playing a harp to attract and distract them and by persuading them to change to human form, while Caoilte cast a spear that penetrated all three, thereby killing them.
Clurichaun The clurichaun ( ) or clúrachán (from Irish: "clobhair-ceann" ), is an Irish fairy which resembles the leprechaun.
