Shewis is the demon who holds the Sixty-Sixth Palace. His name is announced during the collective greeting: 'Sixty-Sixth Palace, Shewis.' Haigott mentions having seen 'sixty-six,' referring to Shewis, and wants a clay figurine that Seran gave to him. Shewis was present at the First Palace when all ninety-nine palaces gathered for the first time in ten thousand years.
