When Twilight discovers in the Canterlot Archives that a seventh Element of Harmony exists, this raises a few questions:

1: What quality is this seventh Element?
2: Where is the seventh Element?
3: Who represents the seventh Element?

The answers to these can be found at the source of the Elements itself-- the Tree of Harmony.
