Based on this Blog by AmericanAnomoly

(Something may get confusing unless you read the blog later on, So I highly suggest you check it out if you are a fan of large mares and tales of corruption and weight gain and want to understand this story more)

Anthroquestria's main focus is on the corrupting powers of darkness mixed with the authors fetish fuel to create his own tale to please his inner darkness of the soul. This is simply an alternative tale for myself to please my headcannon and others who want it. Shoutout to American since he is a nice guy who does his thing, just keep drawing my friend.

Celestia is gone, Her own student accept the dark whispers of power and had overthrown her and taken her country. The newly crowned queen now continues down her dark path and growing bigger and stronger for her King Sombra. But a twist in the tale leads to another path of the story... Where a change in the course of events starts to challenge Twilights new morals, sending her further down the path of corruption...

The story features various different stories like the blog does, changing focus at times to showcase problems with different couples or residents. Will focus mostly on 3 different places: Rarity/Trixie and their new married life in Manehatten, King Sombra and Queen Twilight in Canterlot with their new rule and dark powers deciding the fate of the country and The group in Ponyville who have started to notice how solemn things have become and have started arguing on what to do about it.
