Hy-Breasail or Hy-Brasil was a phantom island believed to most likely located near Ireland. Hy-Breasail was said to charm sailors toward it before disappearing, as well as driving many of those who sought it mad. Legends, however, did state it was possible for sailors to land there as long as a flaming arrow was shot into the ground to purify the area but the resident demons would overtake them. Hy-Breasail was also thought to originally be the Island of the Blessed.
