Zug Zug was mage by enchanting the head of an Orc. No, we are not sure why either. He never did make much sense, but he would occasionally throw out random snipits of adventuring wisdom like some kind of talking self help book. He told me once to "treat others how you wish to be treated" while I was stabbing a roving barbarian that had decided to sack my Inn, so take that how you will.
