The rats want to kill the humans, the humans want to kill the rats, the mice want world peace, and the wizards want to rule the world. Any questions?
You start the game with 100 gold pieces with which to buy whatever you want. The table below gives you some items which are so powerful they should be magic but which you can buy if you find a few extra copper pieces in the dungeon. You also get 10 free cheese weapons per adventure, abuse this fact.
