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).
Elim Olfínechta Elim Olfínechta, son of Rothechtaid Rotha, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He succeeded to the throne after his father was struck by lightning. Snow that tasted of wine (Old Irish "oll", "great, ample", "fín", "wine", "snechta", "snow") is said to have fallen in his reign. He ruled for only one year, before he was killed by Gíallchad, grandson of Sírna Sáeglach, the High King who had been overthrown by Elim's father. The "Lebor Gabála Érenn" synchronises his reign with that of Phraortes of the Medes (665-633 BC). The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 787–786 BC, that of the "Annals of the Four Masters" to 1024–1023 BC.
