How to Generate Endless Profit from Selling Captured Lords

1. You must own a city.
2. Capture any lord and take them prisoner.
3. Go to the tavern in your city and sell the lord through the ransom broker.
4. The lord will still be sent to the prison in your city (at least until the developers fix this).
5. Go to the prisoner management menu and transfer the lord from the prison back into your party.
6. Go to step 3 and repeat 3-6 in a circle as many times as needed (capture once, and resell as many times as you want). After you click a lot of times and own enough, if you capture faction leader you can try hire him with his own money.

8. Profit!
