The three scenarios are:
1. Medium map: You have to destroy one wizard.
2. XL map. You have to take and hold five cities. After you take the fifth city, you have to wait until your next turn starts to win the scenario.
3. Large map. You have to cross the great desert and raze a city. You must wait until the beginning of your next turn before you get the winning message.
This is my first attempt to make a scenario and my first attempt to make a campaign. Everything seems to work fine. I wanted to make the campaign four scenarios, but I had a problem with either too many heroes or too many magic items, and I had to condense the last two scenarios into one scenario in order for the campaign to function. Please let me know if you encounter any errors. My apologies if you find unnamed cities. Also, I encountered a couple of guarded yet empty prisons.
