The magic of Xanth was useless in Mundania--until Dor tried honesty!
Dor was having troubles growing up to be the next Magician-King of the
magic Land of Xanth. He wanted no part of running the Kingdom. But now
the Good King Trent was leaving on a trade mission to non-magical
Mundania, home of such weird beasts as horses and bears, so Dor had to
take over as King for a week.
A week passes. No Trent. Then three weeks. King Trent still hasn't
returned. Surely, something terrible had happened; he was apparently
held captive in some foul dungeon, unable to escape. Dor was left with
the burden of ruling--and with Irene, who was entirely too willing to be
his Queen!
His only hope was to enter Mundania and free King Trent. But how could
it be done without the powers of magic? Nevertheless, he started forth
bravely--together with Irene, a golem, a centaur, and a young
ogre--heading for the far south of Xanth.
The entrance to Mundania, of course, lay to the north.
