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).
Vântoase Vântoase are creatures present in Romanian folklore, as a sort of female spirits ("Iele"). Popular beliefs describe them as capable of causing dust storms and powerful winds. They live in forests, in the air, in deep lakes, and use a special wagon for traveling. The "Vântoase" are also believed to be capable of attacking children, and the only protection against them is the mysterious "grass of the winds". In other legends, they are believed to be servants of God.
