prophecy of the bat and eagle

Celestia stood in an empty field, easily the size of Ponyville. The sky was the most pure blue
And the grass was greener than any she had ever laid her eyes upon.

All of a sudden, the image fades away, as if it were a tarp, hiding the field of corpses
That replaced it.

The Solar Princess had to suppress the urge to throw up at what looked like furless minotaurs laying dead on the ground. Most were wearing peculiar blue wool jackets over commoner Clothing, onewearing a tri-tipped hat and cape while some wore very far fetched ones, such as what appeared to be some
Kind of clown, its' lips curled upwards in a psychotic grin.

All of a sudden, Celestia heard a screech and
Looked up in the sky to see a bald eagle
Swooping towards a bat roughly the same size,
Which was doing vice versa.

Celestia instinctively brought an appendage up
To shield her eyes from what she had a feeling
Was going to be the bloodiest battle fought,
Before two symbols appeared in her vision

Hood

Bat

Then, she suddenly woke up, looking around, noticing that she was in her bedchambers in the Crystal Empire, after she, her sister Luna, and her niece Cadence consoled her student, Twilight Sparkle about her role as a Princess of Equestria. Then the doors to her chambers immediately burst open to reveal her sister.

"Sister," Luna began, "what is wrong?"

The elder sister just closed her eyes, calming herself down before speaking, "it was just a dream, Luna."

"You know as well as I that was NOT a dream."
