Paris, 1933. Europe is still in the grip of feudal warlords, the Catholic Church has all the power of a secret police force, and sorcerers stalk the streets at night. Welcome to the world of Rex Mundi. Master Physician Julien Saunière stumbles onto a thousand-year-old brotherhood dedicated to protecting the secret of the Holy Grail—a secret that threatens to drown the world in blood!
Saunière digs deeper and deeper into the mystery of the Holy Grail and finally he uncovers the connection to the Duke of Lorraine. The Duke, meanwhile, is forced to make a bid for power when the king orders his arrest. If he can't succeed, he will surely hang!
