All the players would be nobles from the game, and most are, but although I put in as many nobles from the game as possible, I needed more players than there are in M&B. To have a decent amount of nobles in each team, I added imaginary sons, which have the same last names as some of the others. I also have the kings and claimants (There's a claimant for each realm, saying they deserve to be king. A team of the rhodok king will be rivals with the team of the rhodok claimant) be the chairmen of the teams.
There's 13 teams, with each team facing each other team 3 times during the season, making a total of 36 games.
