1 year after the events of Medici (including his brief tussles with what was left of the eDEN Corporation and the Black Hand), Rico Rodriguez is contacted by his mentor and friend from the Agency: Tom Sheldon.

Sheldon sends him on his latest mission: To liberate Equestria from the (allegedly) tyrannical rule of Princess Celestia, and seize its magic for the Agency.

A/N: Rated T because of violence, possible mild gore and swearing. MLP and all of its characters are copyright of Hasbro, Just Cause and all its characters are copyright of Square Enix. Please don't sue me.
Contains spoilers for Just Cause 3 (including Sky Fortress, Mech Land Assault and Bavarium Sea Heist), and all EqG films up to and including Legend of Everfree.

Just Cause 4 is not considered canon in this story, both because I started it before JC4 was even known to exist, and also because it's terrible.
