At the end of which season the daughters of Airitech would come out of the Cave of Cruachan every year?
Samhain Samhain (pronounced or , ] ) is a Gaelic festival marking the end of the harvest season and the beginning of winter or the "darker half" of the year. Traditionally, it is celebrated from 31 October to 1 November, as the Celtic day began and ended at sunset. This is about halfway between the autumn equinox and the winter solstice. It is one of the four Gaelic seasonal festivals, along with Imbolc, Bealtaine and Lughnasadh. Historically, it was widely observed throughout Ireland, Scotland and the Isle of Man. Similar festivals are held at the same time of year in other Celtic lands; for example the Brythonic Calan Gaeaf (in Wales), Kalan Gwav (in Cornwall), and Kalan Goañv (in Brittany).
Medb Medb (pronounced ] )—later spelled Meadhbh (] ) and Méabh (] )—is queen of Connacht in the Ulster Cycle of Irish mythology. Her husband in the core stories of the cycle is Ailill mac Máta, although she had several husbands before him who were also kings of Connacht. She rules from Cruachan (now Rathcroghan, County Roscommon). She is the enemy (and former wife) of Conchobar mac Nessa, king of Ulster, and is best known for starting the "Táin Bó Cúailnge" ("The Cattle Raid of Cooley") to steal Ulster's prize stud bull. Medb is strong-willed, ambitious, cunning and promiscuous, and is an archetypal warrior queen. She is believed to be a manifestation of the sovereignty goddess. Medb of Connacht is probably identical with Medb Lethderg, the sovereignty goddess of Tara, and may also be linked with the Morrígan.
