Despite this, she and Aurora slip away from Regalia unnoticed and fly after the party. Luxa, however, is forbidden to join the quest, due to not being mentioned in the prophecy. After learning about the Prophecy of Bane, Gregor and a group of questers set out on an adventure across the vast Underland river, the Waterway, in order to find and kill a a giant white rat, known as the Bane, before the gnawers can kill Boots. Months later, Gregor and Boots return to the Underland. Luxa, along with her cousin Henry, join the quest for The Prophecy of Gray. There they meet Luxa, the first human they encounter in the Underland. When Gregor and Boots first fall into the Underland, they reach the stadium of Regalia. Afterwards, Luxa wasn't so afraid anymore. Due to their closeness, Vikus was able to convince the Council to allow them to become bonds earlier than usual. As a result, she spent all her waking hours in the air with Aurora.

Shortly after, she went through a time where she never felt safe on the ground. When Luxa was just a girl, her parents were killed by King Gorger. In addition, she has multiple cousins, including Henry, Nerissa, Howard, and Hazard to name a few. Luxa is the daughter of Judith and her husband, as well as the granddaughter of Vikus and Solovet. She is described as having 'real attitude' by Gregor and is weighed down by responsibility and grief, but she is a good, strong leader and a loyal friend. After Henry's death, she becomes even more open with Gregor, eventually leading to their friendship. This side first began to show itself upon meeting Boots and even more so when she was apart from her cousin, Henry. It eventually became clear, however, that she had a much kinder and friendlier side. When she was first introduced, Luxa was abrasive, cold, and oftentimes mean, especially to Gregor. According to her, she was clawed by a rat in The Labyrinth after being separated from the rest of the party in The Prophecy of Bane. In The Curse of the Warmbloods, she has a new scar running from her left temple to her chin. Later on, however, Luxa cuts off her hair before joining the ' questers' to fulfill The Prophecy of Gray, leaving it so short that Gregor initially mistakes her as a boy. When Gregor asks why she cut her hair, she simply states that long hair is dangerous to have in battle. When she was first introduced, her hair was woven in an intricate braid down her back and, if let down, reached her waist. Her voice is described as cold, clear, and foreign.

Like the rest of the Underlanders, Luxa is described as having platinum blonde hair and violet eyes, with skin so translucent that you can see the veins underneath. 4.3 Gregor and the Curse of the Warmbloods.
