A Mankind Witch

In an alternate universe ruled by magic in which the Holy Roman Empire controls Europe, a sacred relic, the Armring of Telmark, is stolen from Odin's temple in a pagan Norway, a theft that could ignite a bloody war with the Empire, unless Corsair-Captain Cair, aided by Prince Manfred of Brittany, can find the missing treasure and rescue Signy, the stepsister of King Vortenbras.
