I can't believe how big both universes are.

Far in the future, Earth is nothing but a distant memory. ​Humanity found a new home in Eittera-a massive planet spanning eight vast continents. Here, civilization didn't just survive; it thrived, rebuilt from the ashes of the old world. Empires rose, technology leaped forward, and it was all thanks to one priceless, revolutionary resource: Mana. ​But abundance breeds greed. ​The year is 121,221. The fragile peace has shattered. The planet is plunged into a ruthless, global war for survival and supremacy. At the dark heart of this conflict stands the Cartella Company, a colossal mega-corporation that has seized monopoly over 80% of Eittera's Mana. ​In a world built on cold steel, dystopian smoke, and blood-soaked resources, Cartella rules from the shadows with an iron fist. As nations clash and the corporate war machine grinds everything to dust, one question remains: Who will control the lifeblood of Eittera, and at what cost? ​Welcome to Eittera. The war for the future has just begun.
