Successor game rules, draft one.

That could certainly be fun. In LotR I developed a rule set to run chariot races with random results but with enough detail to produce interesting and unique outcomes each time. I posted the rules here. A similar system could be used for dueling if you do it in a 'fencing' system, a lot like boarding ships in Sid Meier's Pirates (if you ever played that). The basic idea being that you've got a game board of 7 squares in a single row. Both duelists start in the middle, on square 4. Die rolls are used to determine what happens. For instance, on a roll of 1, duelist A pushes his oppenent back a square, or on a roll of 6, duelist B pushes his oppenent back 2 squares. For flavor, there can be other effects, like an injury which reduces someone's chances in future rolls, or perhaps someone owns an excellent sword which gives them an advantage on a roll once or twice in a duel. When a person is pushed off their last square, they lose. There is then a roll to determine whether they were injured or killed in the process.

Tincow's use of the word 'fencing' made me wonder: How exactly did duels work in the middle ages, particularly the 11th-13th centuries that will likely make up most, if not all of KotF. Does anybody know what weapons, equipment etc. were used. I wouldn't want realism to detract from the fun and functionality of the dueling system, but I'd rather avoid us fighting with rapiers and epees and smallswords.

I don't know a whole lot about medieval duels, but they definitely were not like fencing. I just used that term because it has a similar physical setup, with both fighters starting in the middle, and people spar forward and backward without variation to either side. That's easy to keep track of in a numerical system.

An alternative to dueling that might get used a bit more would be drinking challenges. Have an argument? Settle it by drinking your opponent under the table.
