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).
Clachan A clachan (Irish: "clochán" , ] or "clachan" , ] ; Scottish Gaelic: "clachan" , ] ; Manx: "claghan" , ] ) is a small settlement or hamlet in Ireland, the Isle of Man and Scotland. Though many were originally kirktowns, today they are often thought of as small villages lacking a church, post office, or other formal building. It is likely that many date to medieval times or earlier – a cluster of small single-storey cottages of farmers and/or fishermen, invariably found on poorer land. They were often related to the rundale system of farming. According to David Lloyd, the Great Famine in Ireland (1845–49) caused such disruption to the social system that the clachans there virtually disappeared; many in the Scottish Highlands were victims of the Clearances. In some cases, they have evolved into holiday villages, or one or two houses have taken over, turning smaller houses into agricultural outhouses. Remains can be seen in many upland and coastal areas. Some are clustered in a dip in the landscape, to protect from Atlantic winds, but others stretch haphazardly along main roads.
