> Knights would get some of their wealth from looting cities and the dead, also Knights used to pay Lords and Nobles 'Shield Money' and that way they didn't have to join the King's army during a campaign. As well as this there are tourneys which, whilst initially costing a lord in prizes (Another way for a knight to make some money.) and the expenses of setting it up, gains a lot more as lots of people with gold to spend turn up and inject cash into the local economy. Lots of small tourneys were held all year round as it was a way for knights to keep their skills sharp, since they only really needed to serve their lord about 50 days of the year.      

This is great input, thank you. Shield money will no doubt be an option as will looting. I did have tournaments planned as well, though the amount of people being able to hold them will be limited to counts and the duke once a year. Those who want to participate pay a fee and part of the total fees goes to the winner of the tournament while a part goes to the organizer, so it can be a source of income for both. But since one year will only last 4 RL days, perhaps we should limit it to one tournament per year just so we don't have to write about tournaments every day. Maybe just describe the most notable one and mention others but not take them into account when calculating money.

As for 50 days per year, how exactly did that work? Who determines when they are serving? Was there a specific time or were they called upon when needed and could not be kept for longer that 50 days after that call? 

Also, could counts in a duchy grant knighthood to a person or is that ability reserved only for the highest title in the realm, in our case the duke? I'm going to follow logic and assume they do have that power but will wait for confirmation.
