Students at the Royal Magic Academy are given a mirror with a crystal in that helps them to control their magic. All Fillies also have a magical crystal in their crowns.
Crystals of Rare Powers
The term Crystal of Rare Powers (CRP for short) is first used in The Lost Mermaid. It appears to refer to the rarer and more powerful crystals in Funtasia, such as those Principal Sparkle has in a locked cabinet in her office. In Teacher for a Day, she is holding a staff meeting to discus the treatment of a newly-discovered crystal.
