Question: Which castle is named after an Irish legend warrior and is located on the Isle of Skye?
Context: Abhartach (also avartagh, Irish for dwarf) ] is an early Irish legend, which was first collected in Patrick Weston Joyce's "The Origin and History of Irish Names of Places" (1875).  Abhartach should not be confused with the similarly named Abartach, a figure associated with Fionn mac Cumhaill. Fedlimid Rechtmar ("the lawful, legitimate" or "the passionate, furious") or Rechtaid ("the judge, lawgiver"), son of Tuathal Techtmar, was, according to medieval Irish legend and historical tradition, a High King of Ireland.  His mother was Báine, daughter of Scál.  He took power after killing his predecessor, and his father's killer, Mal mac Rochride.  He is said to have instituted the principle of an eye for an eye into Irish law, after which the behaviour of the Irish improved.  The completion of the road construction around Tara is attributed to him.  He ruled for nine or ten years before dying in his bed, and was succeeded by Cathair Mór.  One of his sons, Conn Cétchathach, would succeed Cathair.  Two other sons, Fiacha Suighe, ancestor of the Dal Fiachrach Suighe, and Eochaid Finn, are named in medieval sources.  The "Lebor Gabála Érenn" synchronises his reign with that of the Roman emperor Marcus Aurelius (161–180).  The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 104–113, that of the "Annals of the Four Masters" to 110–119. Maeve, Maev or Maiv is a female given name of Irish origin.  It was spelled Medb in Old Irish (] ), Meḋḃ, Meaḋḃ in Middle Irish, Meadhbh in early modern Irish (] ), and is now spelled Méabh (] ) or Medbh in modern Irish.  It is usually Anglicised as Maeve , with variants such as Maev, Meave, Maive, and Maebh.  The name means 'intoxicating' or 'she who intoxicates' and has strong links to mead, an ancient honey wine typically consumed during a marriage ceremony.  It is rooted in the Irish legend of Queen Maeve or Medb, one of the main protagonists of the early Irish legend "Táin Bó Cúailnge".  It is also associated with the fairy queen Queen Mab of Irish and English legend. The Children of Lir is an Irish legend.  The original Irish title is "Clann Lir" or "Leanaí Lir", but Lir is the genitive case of Lear.  Lir is more often used as the name of the character in English.  The legend is part of the Irish Mythological Cycle, which consists of numerous prose tales and poems found in medieval manuscripts, but originally part of a strong oral story telling tradition. Scáthach (Scottish Gaelic: "Sgàthach an Eilean Sgitheanach" ), or "Sgathaich", is a figure in the Ulster Cycle of Irish mythology.  She is a legendary Scottish warrior woman and martial arts teacher who trains the legendary Ulster hero Cú Chulainn in the arts of combat.  Texts describe her homeland as Scotland ("Alpeach"); she is especially associated with the Isle of Skye, where her residence "Dún Scáith", or "Dun Sgathaich" (Fortress of Shadows), stands.  She is called "the Shadow" and "Warrior Maid" and is the rival and sister of Aífe, both daughters of Árd-Greimne of Lethra. Kylerhea (Scottish Gaelic: "Caol Reatha") is a village on the east coast of the Isle of Skye, in the Scottish Highlands, overlooking Kyle Rhea, a strait splitting Skye from the Scottish mainland.  A ferry service has linked Kylerhea with Glenelg on the mainland for centuries.  The first car ferry was introduced in 1935, with a turntable located on the boat.  Despite the existence of the now toll-free Skye Bridge, this ferry service, undertaken by the MV "Glenachulish", still runs during the summer months, due to its popularity as the more scenic and traditional route between Skye and the mainland.  This service is now community-owned but used to be run by Murdo Mackenzie for almost twenty years. Þórkell Þórmóðarson is a character from the mediaeval "Hákonar saga Hákonarsonar", a kings' saga composed in the last half of the 13th century.  The saga relates that in about the year 1230, a Norwegian-Hebridean fleet sailed down through the Hebrides, where it attacked certain islands there, and proceeded on to the Isle of Man.  As the fleet made its way southward through the Hebrides, several members fought a battle with Þórkell at "Vestrajǫrðr", near Skye.  The exact location of "Vestrajǫrðr" is unknown, although Loch Bracadale, Loch Dunvegan, and Loch Snizort, all located on the western coast of Skye, have been proposed as possible locations.  According to the saga, Þórkell and two of his sons were slain in the encounter, however a third son, named "Þórmóðr", managed to escape with his life.  Early the next year, the fleet headed northwards through the Hebrides back home.  When it approached the island of Lewis, a man named "Þórmóðr Þórkelson" fled for his life, leaving behind his wife and possessions to be taken by the marauding fleet. Caisteal Maol (Gaelic: "Caisteal", 'Castle', "Maol", 'bare') is a ruined castle located near the harbour of the village of Kyleakin, Isle of Skye, Scotland.  It is also known as Castle Moil, Castle Maol, Dun Akyn, Dunakin Castle Dun Haakon and Castle Dunakin.
