Quest members •
Gregor: The twelve-year-old protagonist of the novel; a "
rager" and the Regalians' "warrior". He is
bonded to the
flier Ares and is a close friend of the princess Luxa. The knowledge that he will soon be leaving the Underland forever causes him to conflict with many of his friends, when they act as though he will never leave. •
Ares: A large black flier (bat) bonded to Gregor. He is brave and much stronger than the average bat. During the journey, he is a source of strength for the other quest members with his calm and resourcefulness. •
Luxa: The rebellious future queen of Regalia. During the period between
Gregor and the Prophecy of Bane and
Gregor and the Curse of the Warmbloods, she and her bond Aurora were trapped in
the Jungle and became close friends with the
nibbler colony there. It is that colony's request for help that motivated her, Aurora, Gregor, and Ares to begin their quest. She later makes the "Vow to the Dead" at the site of a nibbler
mass execution, essentially pledging all her personal and political power to avenge the
mice's deaths. •
Aurora: A golden bat bonded to Luxa. She is one of Ares's only friends. She tends to side with Luxa in arguments, particularly on the subject of the mice colonies, as they were great friends to her as well. •
Boots (Margaret): Boots is Gregor's two-year-old sister. She is known as "the princess" by the crawlers. She becomes fixated with an Underland children's song that is later determined to be one of
Bartholomew of Sandwich's sinister prophecies in disguise. •
Hazard: Luxa's young
halflander cousin. He gifted with languages, and also has unusual knowledge about life in the Jungle, which makes him a great asset to the quest group. He turns seven early in the novel. He and the young flier Thalia are very close friends. Hazard sustains a head wound immediately after the traveling party enters
the Swag and is incapacitated for most of the trip. •
Thalia: A very young peach-colored female bat. She absolutely loves jokes, and the other quest members often try to get her to laugh when she is terrifies by the number of dangerous circumstances they encounter on their way back to
Regalia. She dies in the eruption of "the Queen" volcano, because she is too slow to outfly the
volcanic ash and too inexperienced to hold her breath while flying. Ares, who blames himself for being unable to carry her away fast enough, lays her to rest with some mice recently executed by rats. •
Howard: Luxa's capable older cousin, and a kind of older brother to her. Howard is training to become a doctor, and is remarkably tolerant towards other creatures, with the notable exception of
shiners (whom he blames for the near-death of Luxa and Aurora). •
Nike: A black-and-white striped bat, the daughter of
Queen Athena. She becomes close to Howard, who lost his bond
Pandora during a previous quest. Like Howard, she also dislikes
fireflies. •
Temp: A
crawler and friend of Boots. He is not very good at speaking
English (which leads many to look down on him somewhat), but he is patient and wise, and has finely tuned natural instincts which save the quest members several times. •
Ripred: A grizzled old rat, and a rager like Gregor. The questers find him trapped in a slick
obsidian pit with his
teeth locked together, a form of slow execution and torture ordered by
the Bane. He journeys with them out of the
Firelands and provides valuable insight into the
gnawers' reasons for exterminating the nibblers. •
Cartesian: A nibbler from
the Fount colony whom the questers encounter early on. He is the sole survivor of his colony and is both terribly injured and suffering from an
acute stress reaction (or "shock"). During brief moments of lucidity, he reveals himself to be brave and intelligent, but he spends most of the trip delirious from pain medication. •
Photos Glow-Glow and
Zap: Two hired fireflies who travel briefly with the quest members as a source of light, after their
displaced colony is discovered in
Hades Hall. They desert the group at the first sign of danger. ==Publication==
