Roy died during a war against the Evil God Cult, but somehow, he returned back in time to 30 years in the past where he was just a boy who awaken his summoning magic. 
Just a few days before his death, he became the only Aura user in a world of magic. 
Using his knowledge and experience, he will become an Aura user again, faster than his previous life. 
Accompanied with a shape-shifting black slime, he will make sure to protect everyone he cares about and win against the Evil God Cult.

The Only Aura User In Magic World

First, we need preparation to go to explore this magicless area. I know for sure that if this place has been here for a long time, someone who wants to hide from mages would pick this place to go.

And my guess is that in the past, there could be some Aura users who tried to hide from the Evil God. And this is the most likely place to hide. Though that's just a guess. It's less likely that I will find any Aura user.

Is there any other magicless area in this world? Maybe.

Also, if master level mages are strong enough to survive in this place, it's no wonder that they could use this place as a hiding spot as well. Maybe even the Evil God himself is hiding here. Then it's no wonder that Timmy couldn't detect the Evil God.

Well, this is just one of my guesses. But maybe I can find a clue of the whereabouts of the Evil God.

We have several master level mages now. But they are too inexperienced in fighting without magic. So I can't bring them here.
