It had been a long past four days, you, Samirah al-Abbas, Magnus Chase, Hearth Stone, and Blitzen went on a quest to find Thor's-not-officially-missing-hammer. Nothing but absolute chaos happened in those four days. They'd met Loki, fought a bunch of dead zombies, and worst of all: Blitzen had been stabbed in the gut with the Skofnung Sword. Once you've been stabbed with that sword, the bleeding doesn't stop until death; unless you use the Skofnung Stone to heal it. Well, long story short, Blitzen was turned into stone to stop the bleeding so you all could get to Skofnung Stone to heal him without worrying about him bleeding to death.
You, Hearthstone, and Magnus had managed to (difficultly) get the Skofnung Stone from Hearthstone's dad. Once Blitzen was un-petrified you used the Skofnung Stone to close up his wound. Oh gods, it was a nerve-racking process but it worked.
You all stood around with some kind of relief that you wouldn't be losing another friend on this quest.
Blitzen looked down at his damaged suit: the sword slash in his vest, the heavy bloodstains. "No amount of Lemon juice or detergent will get these out," Blitzen said. "Once fabric turns to granite and back again, the discoloration is permanent."
Magnus and Hearthstone didn't even bother pointing out that he had just been on the verge of death, and that was what he cared about most? You all were just happy he was alive at this point.
