1. Kidnap a princess
2. Steal a baby
3. Find a henchman and commit him to service
4. Overthrow a kingdom and place a new ruler on the throne
If he succeeds, Rune will be promoted to Fiend, if he fails, he’ll be exiled from the villain community forever. Luckily, he may choose two Conspirators, so Rune chooses his best friends Countess Jezebel Dracula and Big Bad Wolf Junior. Only one problem, Rune’s not very evil. In fact, his behavior on the Plot starts to seem suspiciously heroic....
