The Worldwound tore reality apart at the dawn of the Age of Lost Omens, murdering the nation of Sarkoris and unleashing a ravenous demonic horde upon the world. Only the quick action of several other nations of knights, barbarians, and heroes stemmed the demon army and contained it within lost Sarkoris, and for the next century, crusade after crusade tried to defeat the demons only to fail time and time again. Their greatest success, the line of magical artifacts known as Wardstones that stand sentinel along the Worldwound's border, barely manages to contain the demons. So when one of the wardstones is sabotaged, a city falls and the demons within surge out in a massive assault like none before. Even before the Fifth Crusade has begun a city has fallen and some of the crusaders' greatest defenders and heroes are slain. Can anyone rise up against the demon host to prevent the armies of Deskari, the demon lord of the Locust Host, from swallowing the world?
