The Dimensional Tower connects numerous dimensions together. After being caught in a dimensional distortion, a person living an ordinary life on Earth finds themselves falling into the seventh dimension's divine world, where they spend an incredibly long time that feels like eternity. Eventually, they become the most powerful owner of the magical world, but they desire to return to Earth. In order to do so, they must journey to the Dimensional Tower, but it is located in Oskarsås, the capital city of the Celestial Empire, which exists in the 3000th dimension.
