The Tree of Harmony, a sophisticated magitech intelligence built long ago during the glory days of the Crystal Empire, has recently been awoken from her beauty sleep again by anomalous activity.

When the Princess strikes up a conversation, she soon discovers that one of Equestria's greatest defense mechanisms is actually a rather interesting individual, and she's not been alone in the cave for all these years.
