 Hopian has never spoken aloud in any of the book series, so his temper or attitude cannot be interpreted.His name comes from hope, which the opal is the symbol of.In "Secrets of Deltora", hundreds of years before the events of the series, Hopian was revealed to have sensed the growing evil in the Opal Territory's city of Hira (later the City of the Rats) and planned to tear the city down to destroy it.
