100 years ago, humans would suddenly disappear and when they came back, they would turn into mindless monsters. Some would simply burn to death while some people would simply disappear. Never to return. Scientists found out the reason for this was because of a new disease.
The disease was called the contagion, as it could be passed from one person to another if been in contact long enough. But even with the discovery of the disease, they could still not find a cure until, one day. Someone fell disappeared and actually came back. He had gained abilities... no, he gained abilities before falling victim to the disease.
The human spoke of enetering another dimension where he had to battle for his life every single day and after a long time, he could finally leave the dimension and came back.
Then another person survived, and then two. But after surviving, they would disappear yet again into another gate. So humans decided to call the weird occurrences dimensional warping.
After passing through the gates, they felt a strange change within them.
That change brought about DNA mutation and what do you know , humans have abilities now . Powers.
And then they would find out they were in another world apart from theirs, filled with strange beasts and unknown territories that would be home to certain disasters
50 years later, the earth experienced a new change. New plants grew and new monsters and beings came into existence. They called this change as the dimensional ascension.
However, after this dimensional ascension, people no longer disappeared, instead they would just get powers and be called into the gates after six months for a trial.
After the trial, they could be called Awakeneds. The more gates they went into and defeated the guardians. The more powers they unlock.
