Near Lake Superior. But not in it. It's cold in there.
FMA Homunculi invade Middle Earth
The Homunculi of Fullmetal Alchemist Brotherhood invade the World of Middle Earth, halfway between the start of the Hobbit and Bilbo Baggins' 111th birthday party. The tunnels under Amestris' Central City are transported under the ruins of Angmar. The Homunculi are located inside of Father's chamber under the city. Father can not leave the chamber until the countrywide transmutation circle is completed, just as in FMA Brotherhood. How do Father and the Homunculi do? Can they take control of and then destroy Middle Earth?
