Dark Deity is a turn-based combat strategy set in a fantasy universe previously destroyed by terrible disasters. Now the player has to connect the destroyed world together and finally stop the terrible wars so that everyone can live in peace and harmony. But despite the fact that the goal carries only peaceful motives, it will have to be achieved through bloody battles, sacrifices and many murders in order to satisfy the bloodlust of the rulers.

The last thread of hope is practically breaking. Once huge and advanced civilizations fell due to an ancient catastrophe, and the empires disintegrated into many small kingdoms. Their rulers not only did not want to unite the territories again, but also began bloody wars among themselves for resources and global supremacy. The Brooksted Military Academy was closed by King Varick, since students from all lands came there and no one needed such a commonwealth. Until the state of Delhi decided to destroy the peace treaty and start a new wave of battles. The protagonist, together with his student friends, does not want to be cannon fodder and therefore decides to stop unnecessary bloodshed with all his might.

Each Dark Deity character has their own unique abilities that can be used in battle. As the battle progresses, the protagonist will find unique weapons and artifacts to strengthen his squad. Gradually, young people with a desire for light and goodness will turn into real veterans and experienced generals, carrying their banner.
