My prediction for the start of Season 5:

The castle is acting up... such as the rooms spontaneously reconfiguring themselves to match its occupants needs and the internal and external arrangement of the structure changing when nopony is looking. Worried, Twilight has been examining the structure's magical field... and found indications that the building is alive.

Just what is the Tree of Harmony and, by extension, what is the castle that grew from its seed. Following up that question in the Castle of the Royal Pony Sisters opens Twilight's eyes to a mystery that is older than Equestria itself...

From whence came Magic?
