When a wizard is sealed in stone, he gradually loses his powers. Mertavius sealed his fellow Wizzin in stone, and over the ages they have gradually lost thier powers. If a wizard loses all his powers, he dies. Thw Wizzin were so powerful, however, that it would take many eons for them to lose all thier powers. Right now, the Wizzin are high red-level wizards, a far cry from the power they once wielded. I know this because I visited thier home planet, call Wizcania. Mertavius turned it into an inhospitable ice sheet, but the castle that was home to the Wizzin still stands."
