The squabbling goblins who live in the great towers of Clovenstone spend their time fighting and looting. Only clever young Skarper understands that dark magic created by a vanquished sorcerer is rising again.

An army of short, fat, hairy dwarves is tunnelling into goblin territory. They are digging under Clovenstone castle to steal its precious treasure. Goblins love fighting, but Skarper and Henwyn's rowdy tribe is no match for the giant armoured moles of the enemy. They must seek the help of heroes, trolls and ghosts for a battle that will decide the fate of the goblins forever.

The goblins have a visitor. Prince Rhind is on some sort of quest to be a hero, desperate for his place in the hall of fame. But Skarper and his troop of goblins know the prince's plan is a bad one, even if they don't quite know why. Now they must go on a quest of their own to stop him - but Rhind isn't about to let a bunch of pesky goblins get in his way...
