Oera

Oera (pronounced: AIR ah) is the name of the world in the Gādo comic series. Geographically it is similar to real world Earth. This is because they are the same world but at different stages. At some point, Earth experienced an apocalypse level event which nearly saw the end of humanity. After The Awakening, the world became known as Oera.

The full condition of Oera is not currently known as the last remaining faction of humanity found safety in old world United Kingdom, now known as Rastonrad, forming a mountainside settlement known as Eien City.

As an island nation, the populace escaped the worst of the monstrosities which continue to roam across old world Europe, now known as Archeldon.

After The Awakening, humans adapt whatever materials they can find into clothes, weapons, armour, and any other items they might need. Old world technology was completely destroyed in The Awakening. Though fragments of it remain, none of it functions and is purely ornamental or sentimental in purpose. Tools are primitive compared to the Earth that used to be.

Monsters, small and giant, now walk the world, destroying anything in their path. These are the creatures the Gādo protect the last remaining survivors of humanity from.
