The legend tells how there was once a bold and noble knight named Sir Eglamore who was betrothed to the beautiful Lady Emma. Being a lady of considerable beauty she had many suitors but had chosen Sir Eglamore in preference to all of the others. Sir Eglamore, although he loved Lady Emma deeply, was very much the knight errant and often traveled to far off lands to fighting all sorts of foreign foes and having many different adventures.
Although the couple was truly in love Sir Eglamore increasingly spent more and more time away from his lady. Poor Lady Emma came to miss him greatly and her health and sleep became affected. She began to walk in her sleep even being found wandering in dreams in the gardens at times. In her sleep, she began to roam further afield visiting places that were special to her and her sweetheart, Sir Eglamore.
One night she rose in her sleep and roamed beyond the gardens and up to the place of one of their favorite haunts, the waterfall of Aira Force where she stood on the very edge of the ravine. We can only guess that in her sleep she dreamed of the being in the arms of her absent lover.
