Eisei Mahōjin : Ēterion


Magic Items


Magic Council

The Satellite Square: Etherion (衛星魔法陣・エーテリオン Eisei Mahōjin : Ēterion), best known as Etherion (エーテリオン Ēterion), is an extremely powerful Magic Weapon controlled by the Magic Council.[1] After the Magic Council's complete destruction at the hands of Tartaros,[2] Etherion has been completely neutralized.[3]


Tower of Heaven arcEdit

  • Preparations for firing Etherion
  • Main Cannon
  • Main Cannon activated
  • Etherion unleashed

Stated to be a nation-destroying Magic that is capable of transcending space-time,[4] Siegrain tricks the Magic Council into firing Etherion at the Tower of Heaven (in order to gather the 2.7 billion Edeas of Magic Power required to activate the R-System[5]), by stating that Jellal plans to use the Tower of Heaven to resurrect Zeref.[6] After a session of re-voting, during which the Magic Council voted to use Etherion (much to Yajima's chagrin), the preparations to fire Etherion begin, which take one full hour.[7] It is fired after a group of Mages under the Council's control chant an incantation, ending with "We pray to the sacred light, Release Etherion!!", causing a series of glyph-like circles and squares to appear above the Tower of Heaven. Once the preparations are finished, a blinding beam of light is shot down, decimating all in its path until it hits the Lacrima crystals inside the Tower of Heaven,[8] which absorb its energy, successfully turning the Tower of Heaven into the R-System.[9] Natsu later eats the Etherion-infused Lacrima of the R-System, prompting him to enter Dragon Force.[10]


Etherion, once successfully prepared, fires an extremely large, destructive beam of Magic upon the desired location[8] (said Magic contains Fire Magic, among other elements),[11] that completely obliterates the target area, leaving only dust behind.[12]


  • Natsu Dragneel, a Dragon Slayer (who can restore his energy by eating his specific Element), was able to eat Etherion and enter the ultimate state a Dragon Slayer can attain: Dragon Force; even though Etherion is fused with elements aside from fire.[10] The consumption of the other elements, however, left Natsu incapacitated for days.[13]
  • Etherion shares its name with the Ultimate Magic in Hiro Mashima's earlier work, Rave Master. It shares the same destructive capability as its namesake.
