Percy Jackson and the Olympians: Legends

Hearthstone is a tall, pale elf with short, spiky, pale blond hair and pale gray eyes. He wears a black leather jacket, black motorcycle pants and pointy-toed shoes, and a red and white striped scarf.

Hearth is a very loyal friend and has risked his own life multiple times to save both Magnus and Blitzen. He is shown to have a dry and self-deprecating sense of humour which he often exercises when annoyed or happy. He is guarded with his own emotions as he was constantly downtrodden and ridiculed by his father and the elves around him due to inability to hear (as elves cannot tolerate imperfections). However, with Magnus and Blitzen his personality and self-confidence evolves as he is around people who truly appreciate his talents and empathize with his weaknesses.

Hearthstone, more commonly known as Hearth, is a deaf Elf, the son of Alderman and Greta, and the brother of Andiron. He is a skilled and cunning user of Rune Magic. While trying to practice rune magic, Hearthstone accidentally landed in Nidavellir. Since elves can only survive in sunlight, he would have died were he not saved by Blitzen. In Blitzen's home there is a tanning bed that he made for Hearthstone. When Hearth drank from Mimir's well he was given two choices. One was to gain the ability to hear and be accepted, and the other was to stay deaf and practice magic. Hearthstone ultimately chose to practice magic. While under Mimir's service, he was tasked along with Blitzen to watch over Magnus Chase. He took the day shifts, as he needed light to survive, while Blitz took the night. Hearth became a friend and ally of Magnus Chase over time and often worked with Blitz throughout these campaigns.
