The Abandoned Dorm, also known in Japan as the old Blue Dorm, is a setting in Yu-Gi-Oh! GX. A year before the events of the anime, Atticus Rhodes, Yusuke Fujiwara and a few other Obelisk Blue students stayed in this dorm, but over time, they vanished. After the disappearance of these students, many tried to find them, but to no avail and the other students were later prohibited from entering the dorm. A cover-up story was fed to the public, which stated that the missing students were in a Duel research program abroad. The official files of the missing students were stored in the dorm in order to hide them, since no one was permitted to enter.
