prophecy school (?)

in a mythical world known as Anthea, full of wondrous animals, is a school, with three main species. but did you know theres a prophecy of three reincarnation? no? I thought so. but dont worry,I'll explain! see there were three great creatures, one a wizard, a guard and defender.
Rosita, Esmerelda and Astor. they were great legends, but like all living things they died...but legend says the great guardians spirits shall pass on in three young members of prophecy academy. they are the reincarnation.
curious which they are? well read on..
