In this world we explore Athea, a world that has been long forgotten after its "fall".
We will experience the story in the point of view of Reema, a young lady that doesn't know her parents and will see the end with her eyes.
She is a mutated human, called "Xhern", they are a new race born after the adaptation to the Xer.
"Xer", is a form of energy that differs from radiation, it's basically "magic"!
This work has some inspiration on Honkai Impact 3rd (Crystals, Herrschers) and TBATE(Magic). There could be other references, but I basically took the idea from past memories, so I do not remember from where or who made the original stories or world buildings, they probably are from some random unknown Anime or something.
