No One - It appears as a strange sort of city made from various metropolitan apartment buildings and towers, each primarily black in coloration aside from their many windows, which glow yellow - though some are turned off in random arrangements. The buildings are divided between extremely thin and narrow streets, lit by diamond lamp posts and completely devoid of cars or pedestrians - indeed, when you enter the various buildings, despite being furnished with multiple objects, none of them seem to have anyone living inside it - creating a strange and disturbing ghost town. At the center of the town is a much larger building which dwarfs all others, rising like a skyscraper above, looking similar to the empire state building at its lower portions - though with the palette of the rest of the city - before being covered in various moving screens displays around halfway through, depicting strange images such as disturbing eyes, hands grasping each other, spinning dots, and radio static, while above these screens the tower transforms to be made of a pristine white metallic material of some kind, with structures more akin to that of a castle sticking out its sides, such as various towers, bridges, and similar such things, with the very top of this structure culminating in a roof that seems to take the shape of a pale, jagged crown of some kind, with a black marking of Lucia's symbol dominating the front of this white portion in general. The interior of the tower is mostly similar to the topmost floor in aesthetic, even when one enters through the lower portion, consisting of white, monochrome halls with a vaguely medieval yet also futuristic sense to its design and contents, and an overall feeling of loneliness and isolation, with most rooms seeming not to serve really any purpose at all despite how many of them there are. Those who fall in the tower will be reborn as Forgotten, serving as the method of recruiting new forces within the base, while the defense is handled in a unique fashion - every 3 floors (out of a total of 18) will host an arena that one of the Forgotten within the tower will take as their station, and people will not be able to progress to the higher floors in any way until this Forgotten has been destroyed or otherwise defeated. However, there is a limit to this defense, as the Forgotten at the next station must be stronger than the prior one, then the one after that must be stronger than them, and so on, so it's unwise to put your strongest Forgotten at the very bottom of the tower. As the Forgotten do not use ships, there is no docking bay in this fortress. The fortress and surrounding city will crumble into nothing when all the Forgotten making it home are defeated.
