Following Twilight Sparkle's coronation as the sole ruler of Equestria, she decides to extend a friendly hoof to any and all sentient races that wish to join her new kingdom and to everyone's surprise, the diamond dogs agree to an alliance and are soon welcomed into the Unified Equestrian Empire. To cement the deal, they send one of their kind to live amongst the ponies in a kind of trial run. Due to her past experiences with the canines, Rarity volunteers to allow one to stay at her home and is shocked to discover that her temporary housemate is Rover, one of the diamond dogs that once held her captive. However, she strives to make his stay a pleasant one, regardless of anything that happened in the past and the two end up forming a close friendship. Now it seems their friendship is about to get a whole lot closer than either of them imagined.
