Etherion

Etherion (エーテリオン, Ēterion) is a strong group of Angels stationed in Heaven, receiving direct orders from the Archon. The fourteen members of this group are assigned to a certain constellation in the night sky, hence their name.

Background
The organization was formed under direct command of the Archon, the main goal of purging Eden and become the -- if not one of the strongest forces of Heaven for The End War. It is led by Leo Regulus.

It was said that the original members of the Etherion had played a great role during the first waging war between Angels and Demons and was Light's strongest pawn. However, after the two clashing forces were given Heaven and Hell, the group fell into a complete inactivity as its old members slowly faded away over time.

Members
Etherion members are skilled players in different aspects, though they all possess proficiency in Soulcraft and hand-to-hand combat, being handpicked by the Archon themselves.
