Nameless (Dropped)

Demon god and 72 demon lords appeared in desolate era, annihilating and threatening different race's lives, the dark era was full of anarchic lands, small tribes and small kingdoms but nothing could stand in their way, except for one

The hero appeared and after heaven-shaking battle the victor was decided, demon god and his suboordinates were sealed, never to disturb humanity again

Millions of years have passed and this story turned into nothing but legend, nothing but unbeleivable history, however, the time has come, the seal is weakening, the day when they free themselves from chains of eons is approaching

And then a human appears, nameless, clueless, feeble, he just strives to survive, little does he know that further he goes, the more damage he deals to formation, but it's not enough, human is too weak, doomsday is inevitable

Will the new era bring heroes downfall or will they triumph over demons, regaining peace once again?

Only the time can tell
