The Pursuit of Diarmuid and Gráinne

Fionn mac Cumhaill, the aging leader of the legendary Fianna, sought the hand of Gráinne, the daughter of the High King of Ireland. At their betrothal feast, Gráinne was dismayed to find her husband-to-be was older than her father. Her gaze fell instead upon the young, handsome warrior Diarmuid Ua Duibhne. Desperate to escape her fate, Gráinne placed a 'geas'—a magical, unbreakable obligation—upon Diarmuid to elope with her. Bound by honor and magic, Diarmuid reluctantly fled with her into the Irish wilderness. For years, the pair lived as fugitives, sleeping in forests and caves while a vengeful Fionn pursued them across the landscape. Eventually, a hollow peace was brokered, and the couple settled down. However, Fionn's resentment never truly faded. During a hunt on Ben Bulben, Diarmuid was mortally wounded by a monstrous boar. Fionn possessed the magical ability to heal Diarmuid with a drink of water from his hands, but twice he let the water spill out of spite. By the time Fionn's son Oisín forced him to help, it was too late; Diarmuid had perished, leaving Gráinne to mourn the love that cost them everything.

“I put you under a geas of death and destruction, Diarmuid, if you do not take me out of this house tonight.”
