Original Description:

Astral Skies, a Unicorn who grew up in the Everfree Forest with nothing but the cloak she was left there in. A powerful magic user harnessing her love of the stars and constellations, she can conjure an ethereal form of much of anything she wants in a moment, but concentrating on anything else becomes a struggle, and to lose her concentration dispels the conjuration as well… Better not lose it whilst she’s flying! Hard to conjure wings when you hit terminal velocity…

Better up than off; peace!
