Musical Corridor

The Musical Corridor (彩音回廊, Ion Kairou), also known as the Ion Corridor, is a mechanical system that was planned when Ar tonelico was still in construction, and it was built upon its completion with the purpose of being a controller to keep the temperature, atmospheric pressure, and gravitational fields around the Tower stable. There is a console called the Central Controller, which actually only sends the energy and signals necessary to control each one of the 7 floating discs that surround it, called the Hexagonal Plates.

Light Circuits
The light circuits are a system that controls the flow of the light from the Tower's surface to the Central Console, located inside the Tower itself. The light of the sun is refracted by using a large crystal (a Prism), and a Lens amplifies and redirects the light in a way it reaches the center of the Tower. The Prisms are installed in various areas called the Prism Rooms, and each one of them is connected to a Upper Prism Room through special light lines, which transmit the light from a place to other. The light is then concentrated in the Prisms of this room and sent to the lower part of the Central Console. And that console, by receiving that light, it's then able to analyze and automatically control the current temperature, humidity, and atmospheric pressure.

The Seven Junctions
The Musical Corridor is located in the outer walls of the Tower, and around of it there is a system composed by 7 equal parts called the Junctions. They are made up from the seven Hexagonal Plates, and each one accomplishes an specific function according to the signals sent to them from the Tower.

However, there is an exception to this: if one of the Plates was removed by any reasons, the balance would have to be restored so this system could continue fulfilling its functions. At the present time, the Musical Corridor only has 6 Hexagonal Plates because one of them collapsed, breaking its Junction with the other 6 ones.

Geometric Balancer
This is the mechanism that regulates the functioning of the seven Hexagonal Plates. The position of the Hexagonal Plates is always decided according to the relative positions of the Junctions themselves. However, the Tower is very sensitive to even the smallest distortions that may sprout between it and the relative position of the planet, and it's not able to measure these calculation errors. The Balancer is a system that is constantly calculating these distortions, its official name being the Tridimensional Mutual Relative Correction Gyroscope. It always calculates the gravitational fields, and in the case that a distortion appears, it sends a signal to the Plasma Bell to initiate the correction of said distortion.

Router Bus
The Central Console of the Musical Corridor is connected to the Junctions by a network of seven electrical cables. These cables are of extreme importance because if even one of these was cut off, the Plates would fall, making it impossible to control the weather, so they are protected by a very strong cover. The Router Buses are the protections that these cables have, which is essentially a Yuteria cover wrapping the cable. The Yuteria is a metal that was created in the ancient civilizations, and its lighter and harder than ceramics.

The Hexagonal Plates
These are the seven plates that surround the Tower, and the directionality that their waves have depends on the vibrations of each of them. Upon a fixed point, they concentrate the Dynamic D-Waves they produce, and then, these waves begin resonating with other, said resonance being the factor that allows the controlling of the temperature and the level of humidity. This also allows to control the apparition of the clouds and the clearing of the storms. Usually, the output of the waves is so low that even in the point of concentration, they can't be seen by the naked eye. However, when the limiter is turned off and the vibrations turns limitless, the point of concentration is forced to resonate so intensely that it can even produce plasma.
