The Book of Ardon is an atlas mentioned in Crusaders of Might and Magic. It showed the world of Ardon, and consisted of informal surveys and cobbled-together maps. Nomandi considered it "archaic" and "as inaccurate with regard to the topography of this world as a rumormonger is with the facts", but also saw it as the strongest resource in print, and it would serve to give Drake the basics of the known world.
