== Currently Known Clues ==
*A book located outside the school of etiquette.
*Inside the stone circle behind the potions classroom.
* Inside the library, on the top floor at the back.
 
*Inside the cave located in the waterfall located between the campfire and the entrance to the Enchanted Gardens
 
*Inside a hole in the wall close to the entrance to the Pet Care classroom.
 
*Behind a 'Coming later in time' sign that can be found by walking straight forward out of the building where you first spawn, taking the first left arch, walking to the very end and looking behind the sign.
*A bundle of crystals behind the dormitories which have been growing larger ever since the game first came out.
A stone pyramid with a clue that has to do with purple crystals. We know that the purple crystals have slowly been growing larger. So when this says let the magic grow and then says purple crystals at the bottom, it probably means let the crystals grow a little longer and a new world or realm will come from below the crystals.
We currently don't know much more than this.
