Equestria is a land of sunshine and smiles, but what lurks in its dark corners? A human private investigator, masquerading as an earth pony, makes it his business to explore those sinister realms.
He's content with his work, until one day, Applebloom goes missing. Agreeing to help look for her, he has no idea that her disappearance is merely the tip of a colossal iceberg.
He must ask himself how far is he willing to go in order to protect his identity and his friends.
In a game where only death awaits the loser, you must risk everything. Sacrifice everything. Only then do you have a chance at defeating the Grey Arbitress.

Rated mature for torture, violence, swearing. If it's tame enough to go in teen rather than mature, or to remove the gore tag, someone tell me.

Also, I don't plot my stories, or I try not to, at the very least. I think it's more fun to write how I'd expect my characters to react, rather than how I want them to react. As a result, I have no idea if Grey Arbiter will contain sex/clop/whatever else in the future, so the applicable tags may change. That's not to say it'll turn from dark fiction with romance elements into an adventure/comedy (God I hope not), but it might not turn out as you'd expect. Isn't that what you'd like from a story?
