1. Rats will literally eat anything except each other.
2. Ill-gotten gains are never gained in secret. And when they are gained, everyone else suffers as a result.
3. There is no such thing as a “good witch.” They do vary in age, however.
4. Having too much copper is usually a bad thing.
5. Chapels encourage you to destroy your cheap stuff. And doing so is usually a good thing.
6. Villages are where all the action is.
7. Owning estates is generally just not worth it. It's just better to rule provinces instead.
8. Cutpurses don't really steal your money; you'll eventually find it again. Thieves, however, do.
9. The main event at masquerade balls was not the dance but a massive gift swap. Everyone was required to participate in it.
10. Gold is not found at the end of rainbows but in tunnels and treasure chests.
11. Bureaucrats do not take money. They give money.
12. Ghost ships and sea hags are real.
13. Mines never produce minerals from scratch. They are actually alchemy factories, where in most cases, copper turns into silver, silver into gold, and gold sometimes turns into platinum.
14. Contrary to popular opinion, court jesters gave out all kinds of stuff. However, in most cases, the good stuff only went to the people they worked for, and the bad stuff went to everyone else.
15. The only reliable way to stand up to a mountebank is to discard a curse (that he probably gave you earlier).
16. As soon as you try to store something in a cellar, equal amounts come back out. This is because all medieval cellars were built with fully functional, automated dumbwaiters.
17. In medieval times, moats were the strongest form of defense known to man. Not even saboteurs or spies could cross them. However, if a castle was ever unfortunate enough to have its moat run dry on the day it was attacked...
18. And lighthouses were just as strong as moats, though they needed to be up and running before the attack arrived.
19. Spies and saboteurs will always reveal themselves when they go to work. They don't seem to mind this.
20. Contrary to popular opinion, pirates never kept the treasures that they raided. For reasons that historians have yet to explain, they destroyed them.
21. It takes two treasure maps to find buried treasure, even though all treasure maps are identical. This is because the print is so faint that it takes looking at two superimposed maps to be able to read them.
22. Knights who engage in battle will always kill each other.
23. Gravedigging is legal, so long as the stolen goods are not too cheap or too expensive.
24. Once a type of item is purchased off the black market, it will never be available again. Buy 'em while you can!
25. Robin Hood was real.
26. You can't both feed and walk a blue dog. It's one or the other; take your pick.
27. You can buy almost anything you want with contraband. Almost.
28. When thieves pillage, they sometimes decide that they don't want to keep the treasure that they found. If that happens, they don't put that treasure back: they destroy it to hide the evidence.
29. The best time for beggars to produce money is when they are under attack. This is because they have learned how to make the best of their hard lives, and they usually come through when circumstances are the most dire.
30. Adventurers don't go looking for action, fame, or fortune. All they want is treasure.
