Drawn to a shooting star that has fallen on an ice field, Halvar and his men are convinced they have found a fabulous treasure. Sven the Terrible, who is also floating in the neighborhood, has the same thought. But the heavenly debris turns out to be nothing more than ugly, charred stones. Certainly not jewels worthy of taking home to Ylva! Only Vic understands the magnetic value of the meteorite stones: he first uses them as a compass to find their way back to the drakkar, then again as magnets when Sven the Terrible tries to attack and reclaim his "treasure"
