When Medb kills her pregnant sister Clothra, the child cut from the dying woman’s womb, Furbaide Ferbend, survives and lives on an island in Lough Ree. Unaccountably, Medb chooses to live on the same island, where she goes bathing each morning. Learning the identity of the bather, his mother’s killer, Furbaide takes a hardened piece of cheese he has been eating, places it in his sling, and shoots it, hitting Medb squarely in the forehead and killing her.
