Nagasaki

"A city in a valley, surrounded east and west by mountains and north and south by the ocean. This place is so different from Mirage. It feels so... free"
-Khaliah Al-Palmyra
Nagasaki is a medium-sized port city on Japan's Kyushu Island. It the home of the White Cross Order's East Asia school, WCSM Nagasaki, commonly referred to as Mountain Academy. The city is also host the the Mogimachi Mages' Market, Nagasaki Roost, and multiple magic related businesses and corporations, one big one being Pandora's Box. 
Nagasaki and Nagasaki Prefecture are both known for being a gathering ground for magic users, resulting in one of the highest concentrations of mages in the world. 
The city was founded in 1570 by the Portuguese as a trade port. It prospered and grew, eventually becoming a major trade hub and ship-building center. The city was unfounded by an American nuke during the Second World War in 1945, and was then later rebuilt following a reconstruction law passed by the Japanese National Diet in 1949. 
During the cataclysm, a block rift known as The Reflecting Pools, was transported into Mount Kumagamine, south of the city. Following an agreement between the White Cross and the Japanese government, Nagasaki was chosen to be the location of a facility designated to studying the anomaly, which later grew into the Mountain Academy.
