Shaun and the Magic Chair (Paperback) (ISBN-13: 9781496995537)

He told his story to a hawk on Achill Island. He variously transformed into the birdlike creatures of hawk and eagle. He also assumed the shape of a one-eyed salmon.
Satan offers Shaun enough leather to make shoes for thirteen years provided he goes with him after that.
Satan has horns on his head, flames coming from his nostrils and his nails are bent and twisted.

Shaun's story took place long after ancient times and long before modern times.
