You will never escape my giant crab monsters! Wait, how did you escape my giant crab monsters?
The Evil Wizard dwells at the top of an impossibly tall tower on the highest, most unscalable peak of a forbidden black mountain. There, he spends the stormy, moonless nights plotting wicked plots and preparing deadly magical traps for any heroes who would dare attempt to thwart his schemes.
But much to his constant surprise and outrage, the heroes somehow always manage to survive his creatures, catacombs and enchanted pitfalls, reaching the top of the tower and ruining his plans. And no matter how many times he waves his sorcerous staff and rants that heíll get them the next time, things just never seem to go his way. Sorry, Evil Wizard, but thatís what happens when youíre the villain of the story!
