Las Noches

The site once used to be the realm of Baraggan Louisenbairn and back then it used to be a desolate place with a throne in the middle on which King Baraggan sat and commanded his armies and was bored out of his mind. Then the place was conquered by Aizen Sousuke and underwent massive renovations. For starters, he built a roof over it to keep out the rain. Not that it ever rains in Hueco Mundo, but the sandstorms are kept out. Though we're not sure whether there are any sandstorms. Because Aizen wanted his new palace to reflect his new status as god, he built the place big. Really big. It's bigger than some countries, though rather plain looking. Its outward appearance is that of a plain gray dome, which resembles a bomb shelter. That might be intentional, because Aizen wanted it to withstand enemy attacks. But in that case, he should have built sturdier walls. They are really easy to break, despite being quite thick. Inside is a whole city built under artificial sky with artificial sunlight. It seems to serve no other purpose than look good and mess with some of his underlings' powers. Aside from the fancy roof, the interior of Las Noches is plain. There is bare sandy ground and a lot of plain buildings standing on it. The notable ones are described in other entries. There are also lots of giant columns that make no sense. Most people think that Las Noches is so big only because Aizen wants to show off, because it's really inconvenient to have a residence that takes days to cross when it has only a hundred inhabitants. But it actually serves a good purpose: the Arrancar would kill each other if they had to live together in close quarters, so the dome is so big to keep them as far apart as possible.
