In 902, Lebuin's Christian forces, now down to less than a hundred, break down the defenses of Rhonwen's fortress by the sea and storm into the castle. Their numbers are further reduced by deadly traps inside the fortress that have been devised by the wizards of Wales, and the pitiful handful that manage to stumble out of the keep alive are driven off by the combined forces of Merlin's dragon and Atticus' golem. Lebuin vows to return with a stronger force and destroy the wizards.
