Mallory Keen

"Today is free-for-all combat. I love Tuesdays!"

- The Sword of Summer

Mallory Audrey Keen was an Irish Norse demigod, daughter of Frigg, before becoming one of the einherjar. She died while trying to disarm a car bomb and ended up in Hotel Valhalla.

Early Life and Death
Mallory Keen was born in Belfast, Ireland to Frigg and an unnamed father. Mallory had a poor relationship with her father due to his alcoholism. On 21 July, 1972, which later became known as Bloody Friday, Loki disguised himself as one of Mallory's friends and tricked her into installing a car bomb on a school bus, claiming that soldiers were onboard instead of children. Her mother, Frigg, knowing she would die, appeared to her disguised as an old hag and convinced her to disarm the bomb, giving her two knives. The car bomb blew up, killing Mallory, but since she died a heroic death with a weapon in her hand, she was taken to Valhalla.

The Sword of Summer
Mallory lives in the Hotel Valhalla, and is Magnus Chase's hall mate. She, along with T.J., Halfborn, and X, invite Magnus to breakfast with them. With icing sugar around her mouth, Mallory reminded Magnus of a reverse-color-scheme Joker. When the group enters battle practice, Mallory stays by Magnus' side until dying from an arrow through the neck.

Mallory and her friends are recruited by Gunilla to help track down Magnus and take him back to Hotel Valhalla. While their attempt to get him in Midgard was failed by Hearth, the group successfully meets them again in Lyngvi. However, she and her hallmates side with Magnus over Gunilla, and aid him in defeating Surt. In the end of the book, she, along with Magnus, Samirah, T.J., Hearthstone, and Blitzen, are complimented by Odin as the true heroes of Valhalla.

The Hammer of Thor
Mallory is first seen chasing her new hall mate with her boyfriend Halfborn when they run into Magnus. They search her suite and find the symbol of Loki. Before battle practice, Halfborn was adjusting her armor, much to her annoyance. A murder of ravens come and bring their new hall mate to them. They are shocked that Alex is female, as they were told she was male. They head into battle against the dragons and she covers her hall mates during the mock battle.

At dinner, she sits with her hall mates as they talk about Magnus' dream about Loki. She, T.J., and Halfborn escort Alex back to their corridor after dinner.

During the wedding, Mallory, T.J., Halfborn, Hearth and Blitz fight the giants. Following their victory, they return to Valhalla to celebrate.

The Ship of the Dead
Mallory has broken up with Halfborn and is part of the crew preventing Naglfar from launching. She along with her hallmates board Magnus' bright yellow ship and they frantically try to prep the boat and narrowly avoid plunging into the void. She talks with Magnus after his vision of Loki. After picking up Sam and Alex they are dragged underwater by nine women. They surface in a cauldron and are fished out by Aegir. She supports an uncounsous Halfborn and sees Hearth and Blitz are prisoners about to be cooked. She and T.J. support a semi conscious Halfborn while Alex, Sam and Magnus free Hearth and Blitz. Just as they are about to eat one of the sea god'd daughters calls out Magnus. They eventually get Aegir to calm down and convince their host to let them leave, if they can escape his daughters. Mallory drives her knives into one of the maidens and uses them to stay in place. She escapes when Njord arrives and Hearth takes out a wall. When they surface she and the others head below deck to get food while Magnus, Blitz and Hearth speak with Njord.

She talks with Magnus about about the absence of Blitz and Hearth. She insults Halfborn, who is within earshot, before climbing the mast.

When they arrive at York she, Sam and Halfborn watch the ship while Magnus, T.J. and Alex scout out the town.

She discovers that the goddess Frigg is her mother, and also the old woman who gave her her magic, unbreakble knives on the day she died. She helps retrieve Kasvir’s mead by tricking the nine thralls guarding it into killing each other with their own weapons, and then holding open the metal doors with her knives while Gunlod slips the mead through.

During the flyting competiton, Magnus Chase calls her the fiercest warrior of Floor 19 and the glue that holds the team together. She is the one who traps Loki in the magic walnut, and hands him over to the gods. At the after party, she is seen alternately throwing plates at Halfborn Gunderson after reconciling with him.

Appearance
Mallory is described as having green eyes and frizzy red hair. She has a short stature in comparison to her hall mates.

Personality
""She's a sweetheart, once you get past the fact that she's a horrible person.""

- Halfborn Gunderson

Mallory is shown to be brash with a minimal filter, saying whatever comes to her mind. This has her sometimes come off as rude, but getting past that, she's a sweet person. As an einherjar, Mallory has developed a liking for battle. While she regularly insults and berates her hall mates, she in fact is very close to them and is considered the den mother of the group.
