Celestia and Luna receive an unexpected guest. And a very important guest she is. But all of the other ponies don't know who she is or why is she so important. But Celestia decides to keep it a secret.

But since her arrival Equestria has been pledged with full insanity! Now Alice most venture with the Mane six (With Celestias insistence.) To save that most important part of her rotting mind.
