into an ability to control precious metals and gems, which both first view as a curse. Hazel died after Gaea tries to use Hazel's power over earth to resurrect Alcyoneus. When Hazel's mother changes her mind about helping Gaea, Hazel buries herself and her mother under the earth, delaying Alcyoneus's rebirth and killing them both. While Hazel's spirit is being judged, she gives up the chance to go to Elysium to save her mother from punishment, and they are both sent to the Fields of Asphodel instead. At some point before The Lost Hero, Nico finds Hazel in the Underworld while trying to visit Bianca, only to find she has tried for rebirth. With the Doors of Death open, Nico is able to take Hazel to the world of the living through them, resurrecting her and then delivers Hazel to Camp Jupiter. Hazel and Nico are protective of each other, much as true half-siblings. Hazel is described as African American, having cocoa-colored skin, curly cinnamon-brown hair, and golden eyes.

She eventually learns to manipulate her curse, manipulating precious stones and metals and sensing structures underground. She is an accomplished horse-rider and skilled with a spatha. She tames the horse Arion, who eats precious metals. She is unusually knowledgeable about the Underworld because of her time there. During The House of Hades the goddess Hecate insists Hazel learn to manipulate the Mist. Hazel becomes very gifted at this.
