A Wizard in Chaos - Chronicles of the Rogue Wizard, #5

IN A WORLD OF ANARCHY AND CHAOS, ONLY THE STRONG SURVIVE... TO RULE THE WEAKMagnus D'Armand, the Rogue Wizard, travels the stars fighting injustice and oppression, sowing the seeds of freedom and revolution throughout the galaxy. But on the planet Durvie, he may have met his match: a lost colony founded by idealistic anarchists, whose civilization has long since crumbled into utter chaos. Dozens of greedy warlords, ruling through fear and violence, wage never-ending petty wars over land and loot while the common folk struggle just to survive.
Over the centuries, the history and knowledge of the original colonists has been forgotten, and the people have reverted to a medieval state. With no central government to overthrow, it seems impossible for Magnus to restore peace and order - until he discovers the hidden knowledge harbored by the Fair Folk within the countryside's Hollow Hills.
