Clan tradition, preserved in the early 19th century, tells how the Fairy Flag was entrusted to a family of hereditary standard bearers. Only the eldest male of this family was ever allowed to unfurl the flag; the first such hereditary standard bearer was given the honour of being buried inside the tomb of the chiefs, on the sacred isle of Iona. Tradition states that the flag was unfurled at several clan battles in the 15th and 16th centuries; the flag's magical powers are said to have won at least one of them. Another 19th-century tradition linked the flag to a prophecy which foretold the downfall of Clan MacLeod; but it also prophesied that, in the "far distant future", the clan would regain its power and raise its honour higher than ever before. In the mid-20th century, the Fairy Flag was said to have extinguished a fire at Dunvegan Castle, and to have given luck to servicemen flying bombing missions in the Second World War.
