Trench Crusade

Trench Crusade is a grimdark alternate-history setting where the First Crusade in 1099 ended in catastrophe. After the capture of Jerusalem, corrupted Knights Templar opened the Gates of Hell, allowing demonic forces to invade Earth. For over 800 years, humanity has fought an endless holy war against Hell. By 1914, much of the Middle East, North Africa, and surrounding regions have become infernal wastelands filled with trench networks, ruined cities, and battlefields stretching for hundreds of miles. The world resembles World War I, but with demons, living saints, cursed technology, and supernatural horrors, Blood and Gore would be an Understatement in this world.
