The Sword of Torunn was a powerful weapon forged from Uru.
It was stolen by the Dark Elves during an attack on Nidavellir. It was taken to Vanaheim, where Heimdall sent Thor to recover it. Here he met up with his friend and ally Hogun. The two forced the Dark Elves out of hiding once they defeated the Horned Marauder, forcing Thor and Hogun to fight through the Elves and their remaining Marauder allies. After defeating a Kronan allied with the Marauders, the Asgardians were able to recover the Sword.
