Lower Areas of the First Tower of Ar tonelico

This name refers to the areas of the First Tower of Ar tonelico that are located below the Terraced Fields, and are separated from the upper floors by a barrier wall, made to keep the poisonous gas from the Sea of Death from going up.

Not much is known about these areas, given that no one has visited them in the last 700 years. However, Shurelia is still able to sense anything that happens down here, and can somewhat monitor the systems in case anything happens.

The few things that are known about the lower areas of the Tower is that the Orgel of Origins, the Parameno Room and the four Paramenos Discs are located somewhere in them, and continue existing even in these conditions, since if they had disappeared or had been destroyed, the First Tower would have lost its power source, and completely shut down, killing all of the Pureblooded Reyvateils, dropping the Wings of Horus into the Sea of Death, and deactivated completely the Musical Corridor.
