"Garm howls in Hel, and the wolf runs free."It's late Winter, and Robin's still isn't used to Asgard.Last year she left Valhalla without permission. "I don't want to fight and die at Ragnarok," she told her new friends. "I want to win!" Every day, they swore their oath on her magic sword Frostbite, even the snarky squirrel Ratatosk.
