Tenet Noctis (2019)

A group of Knights Templars are besieged by Saracens but that's the least of their problems. They face an enemy that is far worse, an evil from biblical scripture. The Knights must do the unthinkable and unite with their "enemies" if they have any chance to survive this evil which besets them. It is a gritty tale of religion, tolerance, and unity, set in the midst of abject horror.
