Enter a world where empires stand on the brink of war, and terrible monsters tear at the fragile borderlands of men; where decaying cities teem with chaos and corruption, weeping innocents are sacrificed to chthonic cults and nobles live in decadent pleasure while the realm burns; where heroes, wizards, and rogues risk everything in pursuit of glory, fortune, and power. This is a world where adventurers can become conquerors — and conquerors can become kings!
