Note: This is NOT a crossover with Penumbra. I picked the name based on the dictionary definition of the word.
In her wanderings, The Great and Powerful Trixie accidentally unleashes an ancient evil that may spell doom for Ponyville. Cut off from the Princesses as well as the Elements of Harmony, the mortal ponies must face an enemy far beyond their power. It is a time for heroes and sacrifice in the name of all they love. Who will rise to the occasion, and who will fall on the field of battle?
If you do not like to read about ponies dying, stay away.
