 Legend supposed that Hugo was able, via a pact with the Devil, to raise a magical army to his aid, and use them to carry out his will.It is this army of hobgoblins that was considered the builders of Yester Castle.When his daughter Margaret was to marry, Sir Hugo gave her and her husband-to-be, Broun of Colstoun, a hand picked pear with the proviso that should anything happen to this fruit it would spell disaster for the Broun family.
