The Demon's Door Bolt

The year is AD 499. Hell's Gates are open, and Daemon prepares for Armageddon. World leaders believe the breached Door Bolt is but a rumor, and only Prester John and his Grail Warriors are left to fight the Prince of Darkness. But there's a slight problem. Prester John panics and resurrects five handicapped warriors. The sixth warrior is chained to the Rock of Prometheus, and the prophesized seventh warrior has yet to be found. The water-clock is running dry Can the Grail Warriors and steppe barbarians "kill" ten million dead guys and save the World? Maybe... with a little help from Mungo the Obvious, the Machina ex Deus, plus Raphael Jabar and his twenty-seventh Thirteenth Yurt.
