Duke Leopold of Austria (NPC)

Duke Leopold of Austria was a warlord of the 14th century who secretly made pacts with the Red Death. These pacts often involved rites requiring human sacrifice. He eventually experienced defeat and death at the hands of the peasants of Berne, Switzerland. They also desecrated his unmarked grave and removed his vital organs. Thereafter, the Red Death brought Duke Leopold back as a unique mummy. Although the Duke is ashamed of his maiming, he conspires to restore the Hapsburg Dynasty and the Dual Monarchy of Austria and Hungary as a means of implementing the Red Death's power.
