Characters. The Company. The contains thousands of elemental users, and most are hostile. They wish to bring complete destruction to those who dwell on the surface. Their hatred for the surface world stems from the belief that they were abandoned by them, which really isn't true since only the  scientists actually knew of their existence underground.

Chelsea and Shiel both turn against the company in order to get Ruri (Maiden of Life) to safety and away from the company. The Ron. Like the elemental power user humans, the Ron were created by the same scientists. According to Chelsea, they physically resemble dragons of mythology but are merely artificial forms of life. The Ron lie dormant, but the Company intends to use Ruri 's power of life to revive them and set them upon the surface world to punish those who had wronged them so many years ago. The Ron share the same bitterness as most of the Underground humans. When they are finally seen, it is revealed that in their dormant state the Ron resemble dolphins, and only become the dragon-like life forms through the Maiden's power.
