Question: In Irish and Scottish mythology, Uathach was the daughter of a warrior woman associated with which Isle ?
Context: Ferdiad (] ; also "Fer Diad", "Ferdia", "Fear Diadh"), son of Damán, son of Dáire, of the Fir Domnann, is a warrior of Connacht in the Ulster Cycle of Irish mythology.  In the "Táin Bó Cúailnge", Ferdiad finds himself on opposite sides to his best friend and foster-brother Cúchulainn, with whom he had trained in arms under the renowned warrior woman Scáthach.  He and Cúchulainn are equal in all martial feats, with two exceptions: the "Gáe Bulg", a barbed spear which Scáthach has taught only Cúchulainn to use; and Ferdiad's horny skin, which no weapon can pierce. Ogma (modern spelling: Oghma) is a character from Irish mythology and Scottish mythology.  A member of the Tuatha Dé Danann, he is often considered a deity and may be related to the Gallic god Ogmios. Scota is the name given to mythological daughters of two different Egyptian pharaohs in Irish mythology, Scottish mythology and pseudohistory.  Though legends vary, all agree that a Scota was the ancestor of the Gaels, who traced their ancestry to Irish invaders, called Scotti, who settled in Argyll and Caledonia, regions which later came to be known as Scotland after their founder. In Irish and Scottish mythology, the banshee is a "fairy woman" whose mournful wail heralds an imminent death. Connla or Conlaoch is a character in the Ulster Cycle of Irish mythology, the son of the Ulster champion Cú Chulainn and the Scottish warrior woman Aífe.  He was raised alone by his mother in Scotland.  He appears in the story "Aided Óenfhir Aífe" ("The Tragic Death of Aífe's Only Son"), a pre-tale to the great epic "Táin Bó Cúailnge". Beira is the name given by 20th-century folklorist Donald Alexander Mackenzie to the "Cailleach Bheur", the personification of winter and the mother of all the gods and goddesses in Scottish mythology.  She is associated with one of the Celtic creation myths (which usually pertain to local land features) and bears a similar role to Gaea in Greek mythology and Jord in Norse mythology. 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. In Irish and Scottish mythology, Uathach was Scáthach's daughter and thus the niece of her rival and sister Aífe.  Cú Chulainn, who had recently arrived at Scáthach's fortress-home "Dún Scáith" (Fortress of Shadows) to be her pupil, accidentally broke one of Uathach's fingers, and Uathach's suitor, Cochar Croibhe, challenged him to single combat despite Uathach's protests.  Cú Chulainn killed him and became Uathach's lover. The aos sí (] , older form aes sídhe ] ) is the Irish term for a supernatural race in Irish mythology and Scottish mythology (usually spelled Sìth, however pronounced the same), comparable to the fairies or elves.  They are said to live underground in fairy mounds, across the western sea, or in an invisible world that coexists with the world of humans.  This world is described in the "Lebor Gabála Érenn" as a parallel universe in which the "aos sí" walk amongst the living.  In the Irish language, "aos sí" means "people of the mounds" (the mounds are known in Irish as "the "sídhe").  In Irish literature the people of the mounds are also called daoine sídhe ] ; in Scottish mythology they are daoine sìth.  They are variously said to be the ancestors, the spirits of nature, or goddesses and gods. The Gáe Bulg (also Gáe Bulga, Gáe Bolg, Gáe Bolga), meaning "spear of mortal pain/death", "gapped/notched spear", or "belly spear", was the name of the spear of Cúchulainn in the Ulster Cycle of Irish mythology.  It was given to him by his martial arts teacher, the warrior woman Scáthach, and its technique was taught only to him.
