Compared to the rest of the continent, the eastern lands were the most free from demons. The reason for this was dungeons. When mana was introduced into the earth's atmosphere, the very landscape began to be altered.
It led to the formation of what is known as dungeons. Dungeons were special landmasses where rifts opened up. These rifts allowed people to enter special places that were clearly not on Earth.
Entering these rifts, people have been known to return with significant boosts in strength. However, it came at a cost. These dungeons had a 95% mortality rate. Yet, with the world the way it is today, power was all that mattered, so many cared not for the danger.
Most rifts appeared on the eastern lands, which is why they were mostly free from demons. A group of awakeners who called themselves adventurers had taken over the eastern lands. They took over the eastern lands so they could gain access to the dungeons.
