Las Noches is one humongous construction made entirely of polished, white rock. It is said that takes over 6 days to get from one gate to another. Its size has made it an important landmark for the inhabitants of Hueco Mundo so much as they will refer to locations based on their distance and direction from Las Noches.
Within the large dome of the palace is an artificial sky made to mimic all sorts of weather and climate from the Human Realm. Though mostly set to reflect a sunny day in a desert, it can sometimes be programmed to summon rain or even snow. Each Espada owns a domain that they may mold to their liking while the Privarons are to live on the outskirts of the large dome.
Segunda Etapa, Cero Oscuro and Gran Rey Cero are forbidden within the walls of Las Noches.
NPC Hollows

Carriers are shaped like centipedes with a long, serpentine body that can easily rival that of a subway train in length and girth. In average, their face alone is as tall as a full grown man if not taller. Despite their size, they are actually incredibly fast, capable of the speed of a Sonido once they've picked up speed and reached their maximum velocity. They usually live in the sand and quartz trees between the Forest of Menos and the Sands of Hueco Mundo. Like centipedes in dirty, they can swim freely in the sand, but are still fastest above ground. Because of that, they are commonly used by more intelligent Hollows of Las Noches as rides.
They are devoid of intelligent thoughts and are considered a variation of Gillian level Menos' They can fight, but they avoid to do so, preferring to flee with their incredible speed instead. One peculiarity about them is that they cannot fire Ceros despite being a Menos.

Highly intelligent creatures capable of flying long distances, Messengers are lesser Hollows the size of vultures and are used to convey messages. Their hiding spots are scattered throughout the buildings without Las Noches and are trained to respond to flares of Reiatsu belonging to the Espadas and other Arrancars. They may look like bats, but they are solitary creatures, preferring to live alone rather than in colonies. In fact, they limit their interaction with other Hollows to feeding times when they are not summoned to convey messages.
Their Pesquisa cover an extremely long range, easily going in the tens of miles, but they may only detect entities with powerful Reiasu. Escaping detection is no hard feat and any individual capable of hiding their spiritual presence can successfully ignore incoming messages that way.
