Celestia has been stripped of her throne and title as the Caribou Empire takes over Equestria. And this is all because Discord decided to give the Caribou a powerful magic... But enough about that, what about The Demons of Canterlot? Hideous creatures hidden in the mines below Canterlot, that always look for new victims for their breeding process. Even stranger, some ponies have been disappearing lately. The disappearances aren't even gender specific, random ponies and Caribou have been vanishing lately. How odd.

This is an FoE vs Alien fic where a developing queen works to release its hive.
