The c. 1800 manuscript presented a legend of the Fairy Flag's origin. This legend concerned a MacLeod who went on a Crusade to the Holy Land. On his journey homewards, the MacLeod attempted to cross a dangerous mountainous pass on the borders of Palestine. Here, he met a hermit who gave him food and shelter. The hermit warned the MacLeod of a dangerous spirit that guards the pass, which had never failed to destroy a true believer. However, with the aid of a piece of the True Cross and certain directions from the hermit, the MacLeod is able to defeat the "She Devil"—who is called ""Nein a Phaipen", or Daughter of Thunder". In reward for conveying some secrets that the spirit wanted some friends to know, she revealed to the MacLeod "the future destinies of the Clan". The writer of the c. 1800 manuscript stated that this knowledge was said to have been held by this man's family until its extinction. The spirit then gave the Macleod her girdle, telling him to convert it into a banner. The MacLeod then used his spear as a flag pole. The writer of the c. 1800 manuscript stated that the spear was by then since lost, and that the secrets conveyed to MacLeod were lost forever. The writer also gave his own opinion on the origin of the Fairy Flag. The writer stated that the flag most probably originated as a banner used in the Holy Land, and that it was conveyed back home by the character portrayed in the legend.
