Dungeons & Dragons

Dungeon Master sends the children northward to the town of Helix to attend a local dragon-banishment celebration. On the way they meet Merlin in his magnificent sky castle. The wizard offers to make Presto his apprentice, only if the young mage chooses to leave his friends and stay there for the rest of his life. But is Merlin's once-in-a-lifetime offer all that it appears?

The children come across a knight named Sir John, who helps save them when they are being chased by a giant scorpion. When Dungeon Master sends them to battle a beholder in a distant valley, the children decide the knight is the perfect person to accompany them. The only problem is Sir John, in reality, is an utter coward.

The magical weapons the children use run out of power on them. Dungeon Master tells them they can recharge the weapons at the Hall of Bones. Venger learns of the children's difficulties and decides to intervene to see to his own interests.

The kids come to the aid of a unicorn named Silvermane, the leader of the last unicorn herd, who under attack by wolves. But when their attention is diverted, an old wizard named Kelek kidnaps Uni. The kids seek out the evil man, who is trying to steal all the horns from unicorns to harness the teleportation powers they possess. But they find themselves too late to save Uni, who is now weak and hornless. The kids free all the de-horned unicorns and ask to be taken to the Valley of the Unicorns so they can protect the remaining three from the Kelek. But little do they know that they are leading someone else into the valley with them.

While taking a lesuirely ride through the forest, Dungeon Master is attacked by a Warduke, a bounty hunter who possesses a sword that covers that which it is struck against with ice. He strikes the side of the tree Dungeon Master is perched on, trapping Dungeon Master in a block of ice. When the kids are made aware of Dungeon Master's capture, they set out to rescue him before Venger can claim him first.

The kids must seek out the river that rains upside down. Once a year the river reverses it's course and rains upwards for 60 seconds. And those who are in it can go whereever they desire. Dungeon Master warns the kids that they 'must never touch the beauty that brings the beast,' but Eric picks a flower later in their quest that turns him into a bogbeast. He then finds out that if he cannot undo the spell, he'll be stuck that way forever. So the kids are now stuck in a dilemma, find their way home, or find a cure for Eric.
