Autonomic Nerves are over 1000 years old puppets who have been assigned to watch over the Night by their currently unknown master. Autonomic Nerves are based on the same technology as the mythical beings known as golems, in the sense that they are artificial bodies infused with a human soul. During the time they were created, magic was commonly used by people. It is told that most of the units were destroyed by In-Births, but guessing from Vatista's unit number, at least 10 000 units must have existed at some point in the future.
Autonomic Nerves spend their time in stand-by mode and moderate the situation of the Hollow Night. If a Void or an In-Birth tries to consume too large amounts of EXS, these units awaken and are ordered to exterminate the ones who disturb the Night. During the time that they are activated, they can fight without food, sleep or clothes. Once they finish their mission they are supposed to receive the Completion Command, "Exit Call" ( ) and return to stand-by mode.
Every Autonomic Nerve is equipped with a Decision Control Type Unit (Vatista's wings are the 7th type called Crimson Wing: "Seven Flowers" ( ). It's unknown how many types there are in total.) known as an Aegis-Attributer ( ). It's the type name for the red wings each Autonomic Nerve has on their back.
