The Guardian of the Stone is a powerful daemon used my Tydus to guard his heartstone in Ultima IX.

The Avatar met the daemon after Tydus sent him to a cave north of Moonglow in search of the fictional 'Staff of Wisdom'. The Guardian had been bound by Tydus to guard his heartstone, and Tydus had hoped the daemon would kill the Avatar upon entering the daemon's lair. Instead of attacking, the creature struck a deal with the hero, letting the Avatar take the stone in exchange for his freedom from Tydus. If the Avatar agreed to this deal, he could take the stone unharmed.
