Findabair

Findabair or Finnabair (Modern , ) was a daughter of Ailill and Queen Medb of Connacht in Irish mythology. The meaning of the name is "white phantom" (etymologically cognate with Gwenhwyfar, the original Welsh form of Guinevere). The Dindsenchas also mention a Findabair who is the daughter of Lugaid Laigde.

Though not considered a main character in the Táin, Finnabair occupies a crucial role in the epic. During the war of the Táin, her hand is offered to a succession of warriors in exchange for their sparring with Cú Chulainn. Ultimately her beauty and charms serve as the driving force behind the deaths of hundreds of men, even compelling Fer Diad to fight Cú Chulainn, his beloved foster-brother and best friend, in the single combat which leads to his death by Cú Chulainn's Gáe Bulg.
