Láeg
Láeg, or Lóeg, son of Riangabar, is the charioteer and constant companion of the hero Cú Chulainn in the Ulster Cycle of Irish mythology. His horses are Liath [Macha and Dub Sainglend].
Cú Chulainn sends Láeg to the Otherworld with Lí Ban, sister to Fand, and he brings back bountiful descriptions of the Otherworld in the tale Serglige [Con Culainn]. In the tale of Cú Chulainn's death, he is killed by Lugaid mac Con Roí with a spear intended for Cú Chulainn.
