Blitz leads the group down an alley to hide, but before they get far enough, a web of light engulfs him. It’s Freya calling him back for her earrings. Blitz disappears, leaving the others to defend against the dwarves. Junior wants Sam dead. Magnus wields the Sword of Summer and introduces it by its many accomplishments, to which the sword responds with an audible thank-you, startling him and everyone else. Magnus releases the sword, and it disarms all the dwarves, who retreat. Magnus thanks the sword by name, and the blade asks for a different name, settling on Jack. Magnus reaches to sheathe Jack, who warns him not to do so yet. As soon as Magnus takes up the blade, he will feel as tired “as if you had performed all my actions yourself” (328).
Junior returns with reinforcements, including a dwarven tank. Hearth leads Sam, Magnus, and Jack to a chasm at the edge of Nidavellir with a river far, far below. The river will take them out of Nidavellir, but Hearth doesn’t know to where. With the tank closing in, Magnus claims Jack. Exhaustion slams into him, and he needs assistance: “Sam and Hearth helped me leap off the cliff” (330).
Magnus dreams another visit with Loki. They’re aboard the ship Naglfar, which is “made from the fingernails and toenails of dead men” (332). In the interest of delaying Ragnarok, Loki tells Magnus the sword might be safe with his Uncle Randolph, whose house is protected by powerful magic that would delay Surt obtaining it. Magnus doesn’t want to give up Jack and believes the idea is a trick.
Magnus asks Loki why he was imprisoned, and Loki reveals he killed Balder (god of light and Odin’s son). As punishment, the gods bound him to a rock with snake venom dripping in his face and transformed one of Loki’s sons into a wolf so he could disembowel another of Loki’s children. When Magnus protests the injustice, Loki says that’s how the gods operate and asks Magnus if “you really want to charge into battle on their behalf” (338). Magnus has no answer and wakes up.
Magnus wakes to a goat giving him mouth-to-mouth. He asks where his friends are, and the goat points to Sam and Hearth’s motionless bodies before going on about how miserable its life is. Magnus sends healing energy into his friends. Sam wakes, but Hearth remains cold and still. Magnus digs deeper and finds Hearth isn’t waking because “a dense knot of dark emotion sapped his will to live” (340). Magnus manages to wake him with a joyful memory combined with healing magic.
The goat introduces himself as Otis and says it’s okay if they want to kill him because “my master kills me all the time” (342). Otis’s Master is Thor, but Otis doesn’t know where he is. Jack detects Thor’s presence close by. The five set out to find Thor with a warning from Otis that they should avoid giants so they aren’t “butchered and put in a stew pot” (344).
The journey is slow going, and Hearth remains weak. After a bit, Hearth hands Magnus one of the runes, the perthro rune, and asks Sam to tell his story while he rests. Hearth had a brother who died young, and his parents blamed him for surviving as a disabled elf—" a punishment from the gods” (347). Hearth had a choice to either be granted hearing and speech to live a normal life among the elves or to remain deaf and mute to pursue magic. He chose the latter and held onto the pain of his family’s rejection, which allows him to learn rune magic.
The group reaches a rougher part of the river, and Otis suddenly remembers he was supposed to get help for Thor. Thor ordered him to come back quickly, but Otis spent a day watching Magnus and the others lying unconscious, which means there are only three days until Fenris Wolf’s island appears. Otis’s brother Marvin waits on the beach. Thor is close to drowning in the river, and Marvin warns the group “if you don’t figure out a way to help him, I’ll kill you” (352).
As seen in earlier chapters, magic comes with a price, which is shown here in a couple of ways. Jack is both a weapon and a liability for Magnus. Jack can do incredible feats on Magnus’s behalf, but Magnus takes on the strain of the tasks once he takes up Jack. If the stress is too much, it could kill Magnus, and if Magnus dies outside of Valhalla, death is permanent. If Magnus isn’t careful, Jack could transform from a tool to a liability. Similarly, the perthro rune symbolizes the price of magic for Hearth. He chose to hold on to his pain in order to master the runes. Perthro is a cup on its side and has several possible meanings, one of which is an empty vessel for magic to fill. Hearth chooses to be open to the abilities runes offer, knowing too much magic use could kill him.
Chapter 47 shows how the gods are no better than any other race. They have emotions and act on them. Loki’s punishment may not be fair, but even for a god, life isn’t always fair. Magnus’s not trusting Loki’s suggestion to bring the sword to Randolph reveals a few things. First, Magnus learned from his earlier conversation with Freya. He wanted to give up the sword then but did not because of his responsibility to stop Ragnarok. Here, he makes the same choice, knowing he has a responsibility to prevent doomsday and suspecting Loki lies. More than just responsibility, Magnus wants to keep Jack. Magnus’s understanding of dwarven culture and how items have personalities allows him to meet the sword and form a bond, showing his growth as a character. Loki’s suggestion also foreshadows the Epilogue. Loki wants the sword, and if Magnus delivers it to Randolph, Loki will have the weapon.
Chapter 48’s title refers to one of the main characters of Riordan’s Heroes of Olympus series (2010-2014), Jason Grace. In the first book of the series, The Lost Hero, Jason falls unconscious several times and is weakened by magic use, although he is a son of Jupiter/Zeus (king of the gods). The chapter title here may be Riordan nodding to jokes made by fans about how Jason passes out more than they expect for a character with his level of power.
