Hearthstone was born in Alfheim and was rejected by his parents because of his deafness. When he was eight, his brother Andiron was killed by a brunnmigi, a shapeshifter that lives in wells. Their father killed the beast but made Hearthstone skin it, they placed the pelt in his room as a reminder to pay his brother's wergild, a debt that must be paid the deceased. His parents said Andiron should have lived while he should have died. They placed dry erase boards in his room for chores and rewards, chores were granted a small amount of gold while rewards cast a large amount of gold.
When he drank from Mimir's well he was given two choices. One was to gain the ability to hear and be accepted, the other was to practice magic. Hearthstone ultimately chose to practice magic. While under Mimir's service, he was tasked along with Blitzen to watch over Magnus. He took the day shifts, as he needed light to survive, while Blitz took the night.
Blitz wakes up Magnus one morning, and tells him a middle-aged man, and a teenage girl have his name and picture, and he should go find Hearth in Copley Square
After breaking into his uncle Randolph Chase's house, Magnus looks outside the office window and sees Hearth standing next to a statue of Leif Erikson. Hearth uses sign language to try to tell Magnus to get out of the house, but it was too late as Randolph returns home and comes upon Magnus and tells him that they don't have much time and "they" are coming to kill Magnus now that he's sixteen. Hearth and Blitz attack Surt in order to protect Magnus. Hearthstone has swatted away and lands by the railing. He helps a woman get her children out of their stroller and takes them to safety at Magnus' urging.
He and Blitz find Magnus in his room. Before they can explain why they where watching him, the squirrel alarm sounds. They flee to Midgard while Magnus' hall mates distract the wolves and the Valkyries, they land in Fenway. He and Blitz explain that they were told that he was a son of Frey and to watch him. They show him his obituary and the three plan to sneak in to the funeral home before his service starts. He and Magnus plan to meet up with Blitz on the first T stop on Arlington after they get the sword. When on their way to the funeral home, they spot Gomez, a police officer who knows them, and hide. He explains Alfheim to Magnus while they hide. While at the funeral home he stands watch while Magnus finds the sword. He is knocked out and wakes up in an alley. He hobbles into the funeral home and gets Magnus. The two then meet up with Blitz and tell him the sword was not there. They then spot Sam and follow her. When they lose her they decide to go to the charles, Sam then attacks them. He and the former Valkyrie fight until Magnus disarms her. They then let Sam join them. The four then head to a dock where Blitz throws Mimir's head in the water to hydrate it. He and Sam bow in his presence. After that he tells them to find the sword and that they have a week to do it. He offers them knowledge in exchange for their service, but they decline. After Mimir leaves they talk it over during lunch.
When they get to the transportation building's food court, he and Blitz grab a seat and have an argument in sign language. When Sam and Magnus get back, a pigeon threatens to starve them unless he listens to them about the sword. Magnus agrees despite the others urging not to. The pigeon gets their food in the form of an eagle and eats the whole thing. Sam then claims it a jotnar. When it takes off with Magnus they follow them and find him in the Boston public library. When he gets down and tells them what he learned they reprehend him for making a deal with a jotnar nut to go fishing.
When they get to the docks he and Blitz are denied the boat while Sam and Magnus are allowed on it. He stays behind to help Blitz find shelter and agrees to meet the demigods at the library later. During that time he and Blitz do research as to what to do next. They wait for Magnus at the public library and talk with Big Boy while they wait. When he leaves Magnus appears. The three compare notes and Blitz is worried. The Dwarf gives them sandwiches and sleeping bags. Hearth is the first to go to sleep.
In the morning he, Blitz, and Magnus meet up with Sam in the public garden to get to Nidavellir. While Magnus is opening the rift he casts a spell to keep the advancing Valkyries and Einherjar from catching them but collapses soon after. When Magnus opens the rift he is aided by Sam and Magnus into it. The four climb the world tree until they find a knothole the sword wants to enter. He gets stuck and before they can free him, Ratatosk, a huge squirrel appears. Blitz drags Magnus into the knothole while Sam hides him and herself in her hijab.
While they hide he helps Sam along as she is recovering from the squirrel's shrieks, as it's shrieks are insulting. They wonder around the world tree and avoid getting attacked by deer until they reach Alfheim, much to his displeasure. They meet up with Magnus and Blitz in Nidavellir where he hugs Blitz and the four fill each other in. Blitz then tells them Junior challenged him to a crafting contest, loser gets decapitated. After that Blitz takes him and the demigods to his apartment. Blitzen is asked about his story, and Hearthstone tries to stop Blitz from telling his story, which the dwarf says he is fine with sharing. After Blitz heads to his room he tells Sam and Magnus that Blitz is good at crafting but not under pressure and shows them the tanning bed Blitz made for him. He signs that people cheat in the contest, but they can get away with it if they make it look like accidents. He suggests Sam do what she did on the World Tree, she leaves in rage when she hears it. He does not answer Magnus when he asks what that was about and heads for the tanning bed. During the competition he alternates between aiding Blitz and standing guard. When Magnus asks him about Sam, he does not answer. When Blitzen was declared the winner he jumped for joy. After getting the earrings and rope it was discovered Junior lied about knowing the location of the Fenris Wolf's island and saying it was classified information but that Thor might know. He and the others ran for their lives when Junior claimed Sam was a shapeshifter and says she cheated. While running the others duck into an alleyway but he keeps running, he meets up with the demigods and asks where Blitz is and notices the sword is floating. After an explanation he shows them a river leading out of Nidavellir. The three jump when the dwarves find them.
Magnus heals Hearth but senses a lot of grief. The elf tells him he will tell him later. He gets nauseous in the dimly lit Jotunheim. He suggests that they use Jack to find Thor and he rides Otis along the way. Hearth gives Magnus a perthro rune to hold as he rides Otis. When they meet Otis' brother Marvin he says Thor is drowning and to save him or he will kill them, and it is good to meet them. When Magnus slays the giantess attacking Thor he is splashed into a tree and invited to dinner by the Thunder God along with Sam and Magnus, which is Marvin and Otis. Hearth signs that he thinks Thor is annoying but Thor thinks he is complimenting him. He is then assigned to find Mjolnir. He aids Blitz when he falls out of a tree and shares a tent with him.
Hearth leaves Otis and Marvin's head by Thor when they head out. They spend the day climbing a cliff to get to Geirrod's fortress. Once they get to the top they rest and discuss how to get across the chasm. He summons one of Sleipnir's sons and passes out. He is aided on to the horse who jumps off the cliff. When Stanley lands he is helped off the horse and signs out random words. He stays behind with Blitzen as a backup. He and Blitzen free Gunilla- who he holds, and help Sam and Magnus. The five ran into Gerriod and barter for Thor's weapon. The giant agrees in they play catch with him. They anger him and he throws hot coals at them. He dodges them until Magnus causes Geirrod to collapse the ceiling on himself. He dusts himself off and signs complaints to Magnus, who notices Gunilla is gone. He tries to use rune magic against her but she threatens to kill Blitz if he does. He distracts Gunilla by pointing and Sam sends her back to Valhalla. They retrieve Thor's staff and the Thunder God appears. Hearthstone signs his annoyance that Thor can not help them fight Fenris wolf, which Thor again thinks is a compliment. The God sends them where they need to be.
Hearthstone wounds up at Mimir's well. The head said that Hearthstone was now a master of Alf Seidr and gave him a two-pronged staff made of polished oak. He meets up with Blitzen, Magnus, and Sam at Long Wharf. Magnus gives him the Perthro rune, which he attaches to his staff. The four find the dwarf brothers and Blitz says they will try to rob, kill and abandon them. They buy four tickets regardless. Along they way he is practicing summoning and banishing his staff. When they dock he and the others are left on the island to face the wolf.
When they find the wolf he is the only one unaffected by his taunts. He stops the others from approaching him. Soon after Gunilla appears along with two other Valkyries and Magnus' hall mates. When Gunilla orders their arrest Magnus's hall mates refuse. Then Surt arrives and ignites his staff in golden fire. He goes with Magnus, Sam, and Blitzen to re-bind the wolf. Hearthstone uses a shield spell to create more heather. When Fenris slashes Blitzen's throat he uses his strength to form a barrier between Blitzen and the wolf and brands the symbol of Tyr on the wolf's forehead. He aids Blitzen in getting to Magnus and Sam when they re-tie the wolf. When the island starts to fade he and the others race to the shoreline. When T.J. pulls out a Frey Boat everyone gets on. He and Blitz have an argument in sign language about who had a dumber plan but were too tired and ended up having a poking contest.
When they arrive at the hotel they are escorted to the feast hall to have judgment passed. The thanes call him Blitz and Sam Magnus's questionable companions. Just as the thanes are about to pass judgment X reveals himself to be Odin. Once the all-father explains what he has been doing the past two years he awards Magnus and his friends. He offers Hearthstone private lessons with himself to hone his skills in rune magic. Hearth is shocked and accepts Odin's offer. He grants Hearth full access to all nine of the worlds.
He attends the funeral for the fallen Valkyries held in the public garden. He is excited about studying under Odin and agrees to help Blitzen move into his store.
Hearthstone and Blitzen have been hiding out in one of Mimir's safe houses. After one of his private lessons with Odin, he predicted that Blitz would die on a mission. He and Blitz met up with Sam and Magnus in Provincetown to retrieve Mjolnir. He tells them that this is dangerous for Blitzen but finds that he is the best person to find the hammer.

After Magnus heals him he investigates an iron coffin and opens it with a rune stone.Hearth stops cold in his tracks when he sees Gelir's sword, Skofnung. He warns his friends about the blade and readies himself for battle when the zombies draw their swords. Heath uses theuruzrune to increase his size and strength. He destroys the draugrs and Gellir before Magnus calms him down. After that, Loki and Randolph appear. He clings to Blitzen when the sword is drawn and is shocked when Blitzen is stabbed. He cradles his wounded friend and blames Sam for this.
He, Sam, Magnus and a petrified Blitzen head to the Provincetown Airport. He is angry about what happened to Blitz and would not talk. He used the last of his magic to summon bubble wrap and tape to keep his friend safe. When Barry and Amir arrive he recognizes Hearth as one of Sam's 'math friends'. He puts Blitz on the plane before they fly off to his home world. As they are about to take off, he is confused by everyone's reaction to Barry. He sits across from Blitz and looks worried about his friend. Before he and Magnus jump, he straps Blitz to him with his scarf.
They land on the Makepeice property and he gives Magnus sunglasses to block out most of the bright light. On the way to his house they are stopped by two police officers. They asked him if he was on the Makepiece property. Once Magnus says he is deaf, they recognize Hearth as Alderman's son. They then take the two to Hearth's father. When they arrive home they are greeted by Inge, one of the housing staff. His father then arrives and berates him for using ASL and invites his son and the son of Frey in. When he signs, his father tells him to use the slab. He tells Hearth that since he left, his mother has died. He is reassured by Magnus that he is with him. He and Magnus are led to his old room. Magnus is shocked and angered by what his friends parents had him do. Inge suggests they rob the Careful One, a dwarf living in Alfheim. Hearth says it is to dangerous and they could easily die, but Inge has faith in him. The next morning Inge told them where to find the Careful One. He hugged her goodbye and she went away blushing. Magnus teased him about this before they left.
They eventually came across the well where his brother died. They move on after a short pause and eventually come across a promising waterfall. He summons the rune of Thor and blows the river sky high, but becomes more aggressive. Magnus, fearing that innocent fish will die, searches for Andvari and finds him. They bring the dwarf out of the river and return it to normal. The dwarf then tell them he will destroy them. After a brief interigation, Andvari give them the gold and a cursed ring.

Later on, Magnus begins to notice the non-human details in Hearth's appearance - the elf's pupils are strangely reflective, like a cat’s, while his veins are more green than blue under his translucent skin. Also, despite his disheveled appearance at times, Hearth does not ever reek like a normal homeless person – body odor, alcohol, stale grease. Instead, the elf smelled more like pine needles and woodsmoke.
Hearthstone is loyal to his friends as when he helped Blitzen fight Surt to defend Magnus. He also seems to have a kind of dark or acid sense of humor, as shown when he put Marvin and Otis' heads in Thor's arms when he was asleep in The Sword of Summer and in The Hammer of Thor, when he got shot by some Alf police officers Blitzen told him "No more running into stray bullets, you hear me?" he answered "I can't hear you.
