"that question is easily answered," replied ozana. "immediately after queen lurline enchanted the mimics so that they could not attack the oz inhabitants, she flew with me, her fairy companion, to the top of mount illuso. here she left me, giving me certain fairy powers over the mimics and instructing me that i was to remain here at all times as the guardian of oz to prevent the mimics from doing any harm to the oz people should the evil creatures ever succeed in lifting queen lurline's spell. i was not even permitted to leave the mountain to attend queen lurline's fairy councils in the forest of burzee."
