I remeber seeing a few people with a "Duke of Hannibal", how do you get that badge?
I have it and use it, it is Duke of Hannibal, it comes from a side quest in Cool Ranch, check in saloons .
Regarding Hannibal i honestly don't know wich is the reference, it could be historic (Hannibal was a Carthaginian general who fought against ancient romans), or from movies like Hannibal Lecter although i think this would be the less probable reference.
The Duke of Hannibal comes from a side quest in Tumbleweed. Two caracters in the saloon, Clemmons and Huck Sawyer give the quest. I took the Hannibal to come from Mark Twain's hometown, and the basis for some of his stories. Don't know that to be correct, but the Clemmons was Twain's real name. Nice Easter Egg.
