Natalie grew up in her family's mansion, but she preferred being outdoors in the wilderness. At on point she met and fell in love with the Norse god, Frey and the two were in a relationship that resulted in the birth of their son Magnus Chase. She would frequently take him camping and describe his father to him.
When Magnus was six, Natalie and her brothers got into a huge argument at Thanksgiving, thus causing a rift in the family. Magnus never knew what the argument was about though it possibly had something to do with Randolph demanding something from her and she refusing to give it to him. Eight years later, when Magnus was fourteen, Natalie was killed by wolves with "glowing blue eyes" sent by the Fenris Wolf to test Magnus.
Natalie was mentioned frequently throughout the book by numerous characters. She was also seen in flashback made by her son.
Hel tricked Magnus into thinking that Natalie' soul resides in Helheim, the afterlife for those who died out of battle (e.g. old age and illness). Hel offered Magnus a chance to be reunited with his mother if he gave his uncle Randolph his sword Jack, to which Magnus refused as he believed that Natalie wouldn't have wanted that.
At the end of the book, Magnus is given Natalie's ashes by Frey and along with Annabeth, scatters them in the Blue Hills.
Natile is seen in a picture of herself and her brothers in Magnus' suite.
Magnus describes his mom as an adult version of "Tinker Bell". She is a petite lady with delicate features and a spray of freckles across her nose. She has short blonde pixie hair and leaf-green eyes that sparkle with humor. She is known for her love of flannel, denim, and Doc Martens.
Natalie Chase had a life of the outdoor and camping. She was a kind woman who loved her son and had no negative feelings for Frey for leaving them.
- In "The Sword of Summer", it is said that Natalie died two years prior to the events of the novel. Given the timeline of events in the Riordan universe, as The Sword of Summer takes place after the events of Heroes of Olympus, it could be estimated that Natalie was killed around the same time as the events of The Titan's Curse.
