House Opal

Motto: "Tell it to the sky"

Symbol: the opal

House Opal are the secret keepers of the Order of the Stone, in that they collected information and kept it, though they sometimes sold it to the highest bidder. It is believed that they are aware of the locations of all the treasures and the other houses. By the story's beginning, House Opal is down to John Opal and his son, Vincent. House Opal also had the dubious honour of keeping the secrets of the Empire, and most of the royal families and governments of Europa, among others. In a way they are collectors of stories, something which John Opal passes on to Leona and Vincent.
