The Mighty Wizard of Adanax. He comes from a mysterious faraway land and lives high up in his castle, and his motive is to become undefeatable. He only has a fortitude of 3, but he has 3 helpers, each with the same fortitude as himself, who will guard him to his death. If he gets killed he will drop ten gold and he will revive and obtain one more helper. With each helper he gets, their fortitude increases by 0.2 and his fortitude by the same amount as well, and the amount of gold he gives will increase by 2.
If at any time, no knight can defeat him, his motive will be fulfilled and he will disappear off the face of the planet, along with his helpers.
