"Plumeboom" is a great traveler, and he has many friends in numerous fabulous worlds. Country of Aboo is one of such worlds. It is settled by hard-working wormlings, who day after day quarry Magic Crystals that may be converted into any possible item! They've recently faced a real disaster. The two evils, Crowbeak the wizard and the mad scientist Cornix, that had expelled from Orniland, got to know about the Magic Crystals and decided to grab these from the defenseless wormlings, in order to create the Weapon of Darkness. The evils' forces are stronger, but our kind friend Plumeboom is assisting settlers of Aboo. The Magic Crystals shouldn't fall into the evil claws.
