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.
Rhiannon Rhiannon is a major figure in the Mabinogi, the medieval Welsh story collection. She appears mainly in the First Branch of the Mabinogi, and again in the Third Branch. She is a strong minded Otherworld woman, who chooses Pwyll, prince of Dyfed (west Wales), as her consort, in preference to another man to whom she has already been betrothed. She is intelligent, politically strategic, and famed for her wealth and generosity. With Pwyll she has a son, the hero Pryderi, who later inherits the lordship of Dyfed. She endures tragedy when her newborn child is abducted, and she is accused of infanticide. As a widow she marries Manawydan of the British royal family, and has further adventures involving enchantments.
