It was a normal routine mission for Angel Rune. Go in. Remove the demon. Get out. But during this job she learns of a plan to bring a Greater Demon through into Equestria. One who would grow strong from striking fear into the sweet innocent ponies and stretch His darkness to the lands beyond. She knows that it is up to her to stop Him from getting in. But she can't do it alone. It will take everything she has to keep this land safe. Fragile bonds will be tested. Blood lost. Battles won. And scars gained.
