Or maybe we can awaken them... something. I just know that we have tried everything we can think of to try... except this." Without hesitating any longer, Celestia swiveled on her hooves and began to trot towards the exit, prepared for the short flight back to the Tree of Harmony. As she moved, she began to theorize, "Have you ever wondered about those bizarre stones attached to the tree, sister? Perhaps it has something to do with them... maybe they are elements from which the tree draws its power? Or it could be any number of other things for that matter..."
Here she trailed off, stopping as she cut a glance over her shoulder and awaited Princess Luna.
