Warren Burgess is the younger brother of Dale Burgess and a second cousin to Kendra and Seth Sorenson. He is a member of the Knights of the Dawn. He is related to world-renowned Patton Burgess (and his wife, Lena Burgess). He has dark curly hair, hazel eyes, and is described to be extremely handsome by Kendra.
Throughout the series
Warren is only mentioned in this book as catatonic albino. He was also revealed to be on a mission before he became an albino.
Rise of the Evening Star
Warren make his first physical appearance still as a catatonic albino. Warren smiles blankly whenever Kendra touches him: her status as fairykind seems to be the cause. After Seth pulls the nail from the revenant, Warren is shocked out of his coma, but he is still an albino. Warren and Kendra go to find the Fablehaven artifact. During that time he is stabbed in the stomach by a minotaur and faces a giant-acid breathing panther which breaks most of the bones in Warren's body, gives him a venomous snake bite, and sprays him with acid. He is healed by the Sands of Sanctity, which also cures his magically-induced albinism.
Secrets of the Dragon Sanctuary
Warren comes to Wyrmroost with the others strictly to be Kendra's guardian. However, he is gored by a peryton at the beginning of the trek at Wyrmroost and is stored in the knapsack for the rest of the journey. When the group is in the Dragon Temple, trying to defeat Glommus, Warren tries to help the others, only to be put asleep by Glommus. He painfully falls down the knapsack stairs and breaks many of his bones. At the end of this book, Warren is knocked unconscious then trapped in the knapsack by Gavin (Navarog's human avatar) when Gavin lights it on fire.
Keys to the Demon Prison
Kendra arrives in the knapsack with Elise, finding Warren, who looks to be in better shape (as noted by Elise). At first, Warren does not believe it truly is the real Kendra. He thinks she might be a stingbulb, so he tests her powers as Fairykind because Stingbulbs can only replicate physical appearances and memories, not abilities. Kendra proves to him that she is the real Kendra and they exit the knapsack using the Translocator, leaving Bubda, who refused to leave him behind, but Warren swore to come back for him so he does not starve and die. Later in the book, Warren accompanies the group in the rescue attempt at Living Mirage and acts as the fail safe. The rescue attempt fails because the Sphinx knew about it all along and Warren's comrades are captured. However, because Warren was dropped off in a different location than his comrades (since he was the fail safe) he was not captured. Shortly after the failed rescue attempt, Graulas (healthy and new after being healed with the Sands of Sanctity) and Nagi Luna overthrow the Sphinx and takes over the Society. The Sphinx quickly changes sides (only because he refuses to open Zzyzx unless it is under his terms) and with the help of the Sphinx, Warren is able to bust Bracken and Kendra out of the prison at Living Mirage. the three barely survive the Beckoning Grove because one of Warren's nose plugs falls out and he almost falls victim to the fruit. They later pass the three riddles of an actual sphinx to enter the sealed fairy queen shrine (Warren actually teases the sphinx because they passed the riddles so easily). The trio escapes together with the help of Raxtus. Warren also helps on the journey to Shoreless Isle (the place where Zzyx, the demon prison, resides) and also fights in battle once the demons are released. Before entering Shoreless Isle, it is hinted by Bracken that Vanessa has feelings for Warren. Warren seems embarrassed and clears his throat. Additionally, during the dinner celebrating the defeat of the demons, it is noted that Warren is sitting right next to Vanessa. Lastly, Warren is among those who voted for the Sphinx's proposition of becoming an Eternal for the new demon prison.
