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.
Corca Oíche The Corca Oíche, meaning "the race of Oíche" (also Corco Óchae, Corcu Oche, Corco Che, Corcuighe, Corcoiche) was an ancient tribe, possibly of Pictish origin, existing since pre-Christian times in Ireland. It is possible that they descend from the Cruthin, a people whose territory existed near Lough Neagh in north-east Ireland. As such, some sources claim that they descended from the semi-legendary hero Dubthach Dóeltenga, or more commonly that they are descended from Oíche or Óchae, the daughter of Cronn Badhraoi of the Dál nAraidi, and her son Fergus Foga last king of the Ulaid to rule at Emain Macha.
