This is an automatically translated description

The fall of the angels marked the beginning of the era of humanity's confrontation with darkness. The powers have united in a confederation designed to repel the legions of demons that are breaking out of the gates of hell. Their ruler, the mighty Ifrit, guards the gates and sends regiments of plagues into the human world. The several hundred year war ended in an uncertain peace. An ancient artefact has been found in one of the cities of humans, giving humanity and the surviving angels a chance to close the gates of hell and drive Ifrit away. However, a formidable enemy has attacked the city and introduced the reign of disorder and death. Mankind equips a small group of the best warriors and an angel who must pass unnoticed through the enemy's territory and get to the artefact. Only a young chaplain, accompanied by a faithful golem, knows the artefact's properties and purpose. The brave ones will reach the goal or perish in the desert lands of Ifrit, where there is no peace and life, only a faint hope of victory.
