It was an ordinary day...til Twilight entered her library.

Somepony turned her library into a battlefield, and all her precious books are scattered, helpless casualties of war. Some are only scarred. Some have been utterly destroyed.

All of them will be avenged.

Twilight is on a livid rampage to find the culprit and will stop for nothing and nopony til she does.

Celestia help us all.
