Starswirl the Bearded is the most powerful sorcerer to have ever lived, and has dedicated his life to the study of magic in all its forms. Everything from medical spells to determine the gender and type of a foal before its birth, to the mighty mysteries of time itself, Starswirl has had his hoof in it.

But there is one type of magic even he refused to dabble in, one type that no pony in their right mind would.

Until now.
