Void Requiem

You play as a knight who faced off against a terrifying beast called archon the destroyer, a being who harnessed the power of the void.

After nearly defeating archon, he unleashed one final but massive attack that launched the knight far off the tower with a mighty explosion of dark energies, surviving  the attack but it was at a price. They lost all of their powers and was badly wounded. After finally managing to get back up, it was too late. The knight was launched so far that tower was no longer visible, and the land was slowly being corrupted by archon's magic.

It is now your duty to once again,  face off against archon and cleanse the land of his corruption. Archon has a powerful and terrible army with his 3 generals that aid him in his conquest, and his army occupies 4 major areas of the world.
