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.

Day ▋▋▋ - ▋▋:57 PM - Spire Tree Castle, Kingdom of Black Duendes, Spirit Dimension

Chaos suddenly enveloped the Kingdom of Black Duendes.

A flying sword spread black flames that scattered almost everywhere. These flames that could not be extinguished by normal means continued to spread out to anything it touched, flammable or not. It was as if it had a mind of its own as it sought places where most of the Demons and Duendes concentrated.

The slaves that survived the flames escaped from their cages and restraints. Some of them fled, while some aimed for revenge. With their stolen weapons, they charged towards the Demons and Duendes that was already injured by the black flames. Even so, the Demons and Duendes still had the advantage. Many of the slaves died fighting. However, it did not dissipate their thirst for revenge for their lives that were ruined by these accursed creatures.
