Princess Celestia has a nightmare of her faithful student dying in a horrible attack that destroys most of Ponyville.
What is worse, though - is her response within the nightmare.
This story is an indirect prequel to my other story: An Old Guardspony'sLast Duty.

I wrote it as a separate story because mixing too much [Dark] into [Normal] stories is frowned upon – and I wanted to describe a nightmare that is vividly bad enough to make Celestia want to do something about it.
