Nightmare Moon rules Equestria with an iron hoof. Her reign is glorious, and her methods are cruel. On top of that, her short fuse is known across the land as the most dangerous weapon Equestria has ever seen.
This rage tends to be a problem when it is unleashed around her husband, Anon. The poor human is very squishy, and although it's unintentional, he often bears the brunt of her fury. This can sometimes be... fatal.
Thankfully, Nightmare Moon has mastered a spell to make this less of a problem. Nothing will come between her and her husband. Not even death.
...Something that Anon has grown uncomfortably used to.
