The story opens in a vast, ethereal plane, introducing us to a concept that underpins this entire world: the soul that a human possesses. This isn't just a metaphor; it's a tangible force. We see a pair of eyes opening to this limitless potential as the name for this power echoes through the cosmos: Edeya. The narrator explains that this Edeya is the very essence of a person's soul. And at some point, humanity unlocked the secret to harnessing it, becoming able to manifest their own soul's power in the physical world.
