Galatea

She is taking a late-night bubble bath when it hits her. Or rather, its disappearance hits her. At the speed of magic, the wave of absence washes through Canterlot, floods the plains below, spreads out to the far reaches of Equestria, and finally dissipats in the lands beyond. And Celestia knows instantly: I am dead.

It is a well established fact that magic surrounds us all. The air, the trees, the ground below us, all are infused with its flow. How much more so then, are the creatures of this planet awash in its power, and few creatures are more magical than ponies. Pegasi, unicorns, and earthens all manifest this in different ways, but all possess great innate power in manipulating and using this magic. But those who know how to look can not only feel it, but see it too.
