Uncovering
A few years after the Human Rebuild, in the City of Paragon, builders were digging to make a foundation for a new building.

The workers then hit something hard. They uncovered it, and saw it was a rock. When they tried to lift it, something happened. The rock was sent up hundreds of feet, a man going up with it, and another going down under it. The being destroyed the entire build site, turning the entire sit area's remaining foliage to a dead, dreary, and dark plain.

A few weeks later, a few cave explorers went into a cave at the site of the explosion, it wasn't there before. After walking in, a helmet flew out, and no one in the exploration was ever seen again. They left the being to his business, that is, until he fought them back.
