Exallion

It was just a normal morning but it was unknown to many that the apocalypse already started.

The origin was not determined but the infected started to appear after a cosmic event happened just outside of the Earth’s atmosphere.

The people and animals turned into man-eating mutants and zombies while some of the lucky ones gained superhuman abilities. Every living creature that had not "turned" started to evolve as the whole world was affected by the Mutagen.

However, it seemed that Earth also had its hidden side that humans would discover in a very uncanny way.

And was Mutagen the last of it?

Unfortunately, not.

Day ▮▮ - ▮▮:▮▮ ▮▮- Stone Fortress, Eastern Duende Territory

A fortress made of stone, it was the castle that was inhabited by the Duwendes in the eastern mountains for several centuries. Compared to other kingdoms of Spiritual and Elemental Races, it was a young kingdom. However, in terms of defense, it was more powerful.

Before this kingdom was established, the mountain was only inhabited by several tribes and small colonies of Duendes.

It was until an attack of a powerful demonic entity happened. The demon was something that the Duendes had never seen before. It was a tall humanoid with a body that was glowing due to heat. The eyes and mouth of the demon were burning with fire, and it would spit flames to attack everything it saw.
