Sunburst was wanting to learn more about Stygian, the once-forgotten spellmage who assisted the Pillars of Harmony before being revived from Limbo. So after moving into the Castle of Friendship, the stallion invited Stygian over for some tea and conversation. Stygian was more than happy to recount tales of old with Sunburst, since the Vice-Headmare seemed curious about the plethora of knowledge he had. However, when it came to one particular story involving Rockhoof, the topic soon went towards particular spells...

More specifically, a spell Stygian happened to know which could exchange the size of certain body parts from one pony to another~
