The Dark Paths

"humans~"
"your race has been given the opportunity to prove yourselves worthy, do not disappoint us"

Across the earth billions simultaneously heard this voice within their heads. On this day 10% of those between the ages of 16 and 30 awakened some form of power explained to them by a screen that only they could see.
There was one other significant change after the voice spoke and this was the arrival of dungeons. The home of monsters and materials that would quickly revolutionize the world, this new golden age for humanity was quickly called a curse though as upon the first year anniversary of the event a battle occurred that crippled the largest cities in the world.

Now what was once hailed as a golden age became the age of "mandatory dungeons" and survival of the fittest.
