The interior of Croghan Hill in Co. #Offaly belongs to the #Otherworld of Bri Éile. This is named after Éle, a Sidhe. The men of #Ireland were at feud about that maiden. One man after another went to woo her on #Samhain and to each one this used to happen: one of his people was slain. This went on year after year until #Fionn Mac Cumhail put an end to it. He killed #Aed from the Otherworld, who had always killed someone from the followers of the courtship out of jealousy.
