Amir Fadlan, who works in a falafel shop. In The Sword of Summer, Sam is expelled from Valhalla when her video of Magnus' Heroic death is edited by Gunilla, but later joins Magnus, Blitz, and Hearth in stopping Fenris Wolf from breaking free. She is eventually reinstated as Valkyrie and gets another job as Odin's personal aide. In The Hammer of Thor, Sam is unwillingly betrothed by Loki to Thrym in exchange for Mjolnir; in reality, Loki wants the Skofnung, with which he can finally free himself. Sam is then given a task by Odin to head towards Scandinavia and personally imprison Loki back before he is able to invade Midgard and eventually Asgard. In The Ship of the Dead, Sam participates in the quest to stop the Naglfar from sailing in Niflheim and has sufficiently trained with Alex enough that she is immune to Loki's influence. The quest is challenging for her not only because of its danger, but also because she is fasting for Ramadan. As a fighter, Sam wields a Valkyrie axe or dagger. She has also inherited her father's ability to shapeshift into animals, but doing so makes her uncomfortable, as it causes her to become more like her father. Sam wants to become a pilot and enjoys being a Valkyrie because it affords her a chance to fly (albeit through levitation, not piloting). Sumarbrander The Sword of Summer (Jack) was Frey's weapon, currently wielded by Magnus Chase. After Magnus finds out that the sword is sentient, Sumarbrander decides to name itself Jack, and be referred to as a male. In battle Magnus can let the sword attack his enemies on its own or use his own strength and control the sword himself. Either way, it is Magnus who loses energy ultimately, though this loss is delayed until he next grips or sheathes Jack. He bears a grudge against Frey, who 'abandoned' him, by giving him to Skirnir as a price for the latter bringing the former a Giantess with whom he fell in love; he summarises this by once admonishing Frey, saying 'blades before babes'. He reached Boston with one of Skirnir's descendants during the Viking expansion, where he was lost for centuries until he was recovered by Magnus. Alex Fierro Introduced in Magnus Chase and the Hammer of Thor, Alex Fierro is a child of Loki (mother) and Mr. Fierro (father). She/he is gender-fluid,
