This is a list of characters in the Fablehaven fantasy novel series by Brandon Mull.
This information has been categorized into the books the characters were first introduced, in order of appearance. Because several of the characters exist in multiple books, this list will stick to an introduction of the characters, rather than give too much revealing detail about their actions and/or fate.
The stories of the Fablehaven series are revealed to us through the personal experience of Kendra and Seth Sorenson, who are the main characters of the novels.
Kendra Sorenson
Kendra Sorenson, a typical 14-year-old girl, is not at all enthusiastic to go on a mandatory vacation to her grandparents place, while her parents are on a 17-day cruise. However, it is here at Fablehaven, the magical preserve her grandparents oversee, she becomes immersed in a whole new world full of fairies and other mystical creatures hidden to most other eyes. She is described as a good student who rarely takes risks, overly cautious and far from the adventurer and rule breaker that her brother is. But when she is in Fablehaven, it doesn't take long for trouble to find her, as the evil witch Muriel Taggert releases a powerful demon named Bahumat. The situation becomes desperate when everyone but her is captured and she must risk her own life to seek the Fairy Queen for help. As a result of her heart-felt supplication to the Fairy Queen, she becomes fairykind, a status which gives her certain magical abilities to aid her in her subsequent adventures.
Seth Sorenson
Seth Sorenson is Kendra's younger brother, who starts the series at age 11. He has a much more outgoing, risky, curious, and adventurous personality. Seth has great courage, but he has little patience, and he doesn't always think things through. Because of this, he tends to be the source of mischief as the story continues, most often trading batteries with the satyrs Newel and Doren. After learning many lessons the hard way, he eventually becomes more responsible and succeeds in overcoming many obstacles. His efforts against dark forces eventually mark him with the powers of a shadow charmer that, like his sister with her fairykind abilities, he is able to use through the series to successfully complete nearly impossible tasks.
Stan Sorenson
Stan Sorenson is Kendra and Seth's grandfather on their father's side. He and his wife Ruth have not been a large part of the lives of their grandchildren until Fablehaven. He is the caretaker of Fablehaven. Grandpa Sorenson leaves clues about the true nature of the preserve, in hopes that Kendra and Seth will discover the truth that it is a preserve for magical creatures. He is a strict rule enforcer, though Seth still finds ways to get around them. He lives on Fablehaven with his wife knowing that it is dangerous, but he is capable. In the first book he is captured by a witch who is endeavoring to free a demon named Bahumat.
Ruth Sorenson
Ruth Sorenson is Stan's wife, and Kendra and Seth's grandmother. She used to teach college history, and is an expert masseuse. She is missing from the first part of book one, and Stan explains that she is away visiting a relative. She turns out to be the pet chicken living in the house named "Goldilocks". When Kendra and Seth discover the chicken is their grandmother, they seek the witch's help to change her back. After she is restored, she explained later that she had previously lost a confrontation with a Jinn, who turned her into the chicken. Ruth leads the assault on Muriel at the Forgotten Chapel, in hopes to stop her attempts to free Bahumat and release Stan and Lena. She fails, then is captured leaving Kendra alone to save them.
Dale Burgess
Dale is the grounds keeper at Fablehaven. He is a quiet, reserved man who helps Stan Sorenson out with chores and general upkeep of the preserve. Kendra spotted him giving the magical milk to the fairies, and he attempts to mislead her into believing it was not for human consumption. It is revealed that one of the biggest reasons he is staying at the preserve is to take care of his catatonic brother, Warren. Dale is second cousin to Stan Sorensen. He plays only minor, but helpful roles in subsequent books.
Lena Burgess
Lena was introduced to Kendra and Seth as the elderly housekeeper to Grandpa and Grandma Sorenson. She was revealed after Kendra and Seth learn the truth about Fablehaven, as a former Naiad who was married to Patton Burgess, a former caretaker of Fablehaven. She was captured by Muriel and Bahumat in the first book, and was unwillingly restored as a Naiad and returned to the pond by the fairy army by the end of the book. In the second book, Kendra goes to see if Lena will return, but the other Naiads take Lena away. In the third book, the appearance of Patton Burgess, by means of a powerful time-travel artifact, coaxes Lena from the pond, though it ultimately results in her death when they enter their final confrontation to save the preserve.
Maddox Fisk
Maddox Fisk, a grizzly looking mountain man, is one of Grandpa's friends and a fairy broker, which means that he catches and sells or trades fairies. He presents to the Sorensons his collection of fairies that he had gathered from around the world. In book 2 it is mentioned that Maddox went on a mission to the secret preserve in Brazil but contact with him was lost. Rescue attempts were made, but unsuccessful.
Hugo
Hugo is a golem, a manufactured being made of soil, rocks, and clay, animated by a powerful spell and given rudimentary intelligence. He has no will of his own and will do whatever he is told, but he was destroyed in the battle against Muriel and Bahumat. After the battle, the empowered fairies rebuilt him, turning him into a true golem and giving him a spark of free will. Hugo is very strong, about 10 feet tall, and has the general appearance of a large ape made of dirt and rocks with disproportionately larger hands and feet. He is a powerful ally throughout the entire series.
Newel and Doren
Newel and Doren are the satyrs. They are introduced in the series as Kendra and Seth are inadvertently stealing stew from an ogress. The satyrs are light hearted and fun, but they can be conniving. They tell Seth that if he brings them the batteries so that they can watch their portable television they will give him gold. Seth does bring them batteries and they give him gold which they have stolen from the troll, Nero, and later from the nipsies. The satyrs enjoy chasing hamadryads, and playing tennis, and are sometimes invited to parties inside the house. They are described as the "ultimate fair weather friends" and detest work.
Muriel Taggert
Muriel is the first villain of the Fablehaven series. She used to be the wife of a previous caretaker, but she became enamored with dark magic and witchcraft. For her crimes she was imprisoned in a shack on the grounds of Fablehaven, held from using magic by a rope with thirteen magical knots tied in it. The knots could only be undone by a human who asked for a favor of their own free will. The person would blow on a knot and Muriel would use the magical power released by unraveling the knot to grant the person a favor. She was freed by Kendra and Seth when she used the power of the final knot to transform Grandma Sorenson from a chicken to her human self. She then attempts to free the demon Bahumat and overthrow the preserve.
Mendigo
Mendigo is a wooden puppet held together with metal hooks at the joints. He used to be a small toy that Muriel the witch created to keep her company, (she called him a limberjack). When she was freed she used a spell to make him human size and gave him golem like intelligence. He follows any order given by his master. He initially followed orders from Muriel, until fairies turned his will to take orders from Kendra. From this point on he becomes a strong ally. He is quite a bit stronger than he looks, and he can carry two people at once while running.
The Fairy Queen
The Fairy Queen introduces herself not as "a fairy" but as "the fairy" the mother, the eldest sister, though in fact she is not a fairy at all but a unicorn. She does not dwell on Earth, but in a different realm where she cannot be tainted by dark magic. Her only portals to the human world is through her shrines located on some of the magical preserves. The fairy queen shrine at Fablehaven is located in a beautiful park, on an island in the middle of a naiad pond. Unworthy visitors are instantly obliterated, as goes the story of a grounds keeper who was turned into dandelion fluff. Kendra, however, must visit the Fairy Queen for help to save her family, and Fablehaven from Muriel and Bahumat. The Fairy Queen spares her life and through the experience, makes her fairykind, giving her many of the powers of the fairies. With her help Kendra and the empowered fairy army defeat Muriel and Bahumat.
Bahumat
Bahumat is an ancient demon who plagued the Fablehaven area before the preserve was founded. Some Europeans imprisoned him in exchange for ownership of the land that he had terrorized. Fablehaven was founded on this land. He is bound by knots similar to those that bound Muriel, but in greater multitude. He was never bound by the treaty of Fablehaven, and therefore Bahumat has to overthrow the treaty to escape Fablehaven. Bahumat is not seen until the end of the first book as Muriel is trying to release him. She succeeds, but the fairies prevail in the end and imprison him underground.
Nero
Nero is a greedy cliff troll whom Ruth, Kendra and Seth visit to obtain information on where Stan is being held. He is a black, scaly, reptilian humanoid with yellow markings who owns a seeing stone. Nero, a tough bargainer, requests a large amount of treasure, but Ruth convinces him to accept a full body massage instead for the information.
Scott Michael Sorenson & Maria Kate Sorenson
Scott Michael Sorenson and Maria Kate Sorenson are Kendra and Seth's parents. They have only minor roles in this book, as they are oblivious to the magical world their children have been thrust into.
The Society of the Evening Star, an arcane organization, is bent on freeing all captive magical creatures, even the dark ones. Also introduced are The Knights of the Dawn, a secret organization set to combat the evil efforts of the Society of the Evening Star.
Errol Fisk (aka Christopher Vogel)
Christopher Vogel is an agent of the Society of the Evening Star. He met Kendra and Seth outside their school using the name Errol Fisk. He impressed them with his magician's skills, and told them he was sent by Coulter Dixon to get rid of the kobold Case. He convinced Seth to break into a mortuary to get a frog shaped statue, who turned out to be the demon - Olloch the Glutton. He tried to convince Kendra and Seth to accompany him on another mission, but they were warned by Grandpa Sorenson that he was not a friend, and likely a member of the Society of the Evening Star, which he actually turned out to be. He was a boyfriend to Vanessa in book two while the duo were working for the Society.
Vanessa Santoro
Vanessa is a friend of the Sorensons, with a strikingly beautiful appearance, and a fancy souped up sports car. She first appears at Kendra and Seth's home. She has been sent to pick them up and take them to Fablehaven, escaping Errol Fisk, alias Christopher Vogel. She is presented as a keeper of magical creatures. She is a Knight of the Dawn, and helps fellow knights Coulter and Tanu with their efforts to find the secret artifact hidden at Fablehaven, until she is revealed as a narcoblix and traitor. Her abilities give her power to control others while they are sleeping after she bites them. She had been secretly working for the Society of the Evening Star for a while by the time she was revealed. Once her plan is thwarted she was imprisoned in the Quiet Box, but leaves a message with Kendra revealing the Sphinx as a traitor. She is hoping to be released from confinement, expressing her desire to switch sides and help them defeat the Sphinx.
Tanugatoa "Tanu" Dufu
"Tanu", as people call him, is a large Samoan who is introduced to Kendra and Seth as an expert on potions. Warren calls him a "Potions Master". He is a Knight of the Dawn, and was brought in to help recover the artifact from Fablehaven. He gave Seth a mild fear potion and Kendra a mix of embarrassment and shame potion when he was introducing them to his work. He proves to be a skilled adventurer, healer, and in some cases, fighter. His potions come in handy throughout the series.
Warren Burgess
Warren is only slightly mentioned in the first book. He appears for the first time in the second book, but as a catatonic albino living in a cabin. No one could explain Warren's condition, or how he got like that, though efforts were made to restore him. His brother Dale cared for him for almost two years before he emerged from his catatonic state, which happened when Seth defeated the revenant in the second book. He is a member of the Knights of Dawn and was on a mission to find the treasure of the Fablehaven preserve before he was turned catonic/albino. At the end of Book 2, and throughout the rest of the series Warren proves himself to be an experienced adventurer and key player.
Coulter Dixon
Stan Sorenson describes Coulter Dixon as one of his oldest friends, and one of the most stubborn men he knows. Coulter is introduced to Kendra and Seth as an expert on magical items, relics and talismans. He is a Knight of the Dawn, and is brought onto the preserve along with Tanu and Vanessa to help recover the secret artifact. He teaches Kendra and Seth about some of the magical items in his possession, including a magical glove that renders the wearer invisible, how a distractor spell works, and a magic cocoon that allows the occupant to survive any environment. He and Kendra have a feud because he believes that there are some places that it is ok for a male to go but not for a female, which he calls "an outdated sense of chivalry".
Mr. Lich
The Sphinx's bodyguard, and the man who Seth and Kendra follow to their first meeting with the Sphinx. After the Sphinx's betrayal, Mr. Lich is found to be a powerful viviblix capable of reanimating the dead.
The Sphinx
Kendra and Seth were introduced to the Sphinx in the second book. He was well received in the magical community as the most trusted and wise ally. He is described as a black man with short beaded dreadlocks. The Sphinx is the one who tells Kendra she is fairykind, and offers to help her develop her new abilities. He's been a leader for the cause for several hundred years, until suspicions arise when Vanessa reveals that he is a traitor. It is discovered that his ultimate quest is to obtain all the keys to the demon prison - Zzyzx, becoming the greatest enemy of the Knights of the Dawn. The Fairy Queen tells Kendra that he is a man and not another being in disguise, and attributes his age to magical tampering.
Casey "Case" Hancock
Casey Hancock, who introduces himself as "Case" is a goblin-like creature called a kobold. He appears in Kendra's class at school, but only she can see him for what he really is. Everyone else sees him as a blond haired, handsome boy. As Kendra's friends swoon over his good looks, he asks them out on a movie date. He even goes as far as kissing some of her friends, revealing a major case of bad breath, causing them to avoid him. Errol Fisk helps Kendra and Seth get rid of the kobold by having Seth steal a statue that he says is sacred to kobolds. Supposedly, when Case received the statue, he immediately left, under a compulsion to return it to a kobold shrine in the Himalayan Mountains.
Olloch the Glutton
Olloch the Glutton is a demon who spends most of his time in a state of dormancy. While dormant he appears to be a statue of a frog. Seth is tricked into feeding the statue, thereby awakening the demon. The statue bites Seth, marking him as the target of the demon. The demon slowly comes to life and begins an unrelenting quest to find and devour Seth. He eats along the way, and as he eats he grows in size and power. He manages to breach the barriers of Fablehaven, and eventually succeeds in hunting down Seth, but Seth is protected by the fairy cocoon given to him by Coulter. Olloch consumes the cocoon, but Seth passes through the demon's digestive system and is expelled at the other end safely. This satisfies the demon's quest, and Olloch returns to his dormant state.
Navarog
When the Sphinx replaced the current occupant of the Quiet Box with Vanessa, he took into custody the previous occupant. Graulus the Demon revealed to Seth that the prisoner the Sphinx took out of the Quiet Box was in fact, Navarog, the Demon Prince, Lord of the Dragons, and that the Sphinx released him to retrieve the revenant's nail, starting the ball rolling that would plunge Fablehaven into the Shadow Plague.
As the story continues in the third book, a new array of characters and magical creatures are introduced, from new friends at Lost Mesa, to a crowd of beings aiding Kendra and Seth in trying to defeat the shadow plague.
Dougan Fisk

He is 16 years old and goes on the mission with Kendra, Warren and Dougan to Lost Mesa to get the artifact. Gavin stutters sometimes when he talks, which gets worse if he's nervous. Gavin's father, Chuck Rose, was an expert dragon tamer, and kept his son a secret, but was eventually killed by a dragon. Gavin, a natural dragon tamer, can talk to dragons and is not affected by dragon's ability to paralyze humans by projecting fear.

At the end of book 3, Gavin goes on another mission and sends a letter to Kendra saying that he is interested in getting to know her better.

Neil is killed in Lost Mesa trying to retrieve the artifact.

Patton Burgess is Lena's husband and was the caretaker of Fablehaven in the late 1800s. He is mentioned in the first two books, but does not appear until the third book when Seth, with the aid of the Chronometer, inadvertently brings him through time to the present. Patton quickly learns of the plight Fablehaven is in with the Shadow Plague. He knows he only has three days to help save the preserve from being overtaken by the plague. In those three days Patton duels with a centaur, easily convinces Lena to leave the naiad pond again, and battles the dark creatures to defeat Ephira, Kurisock, and the Shadow Plague. Patton revealed that he had defeated the dragon Ranticus, and that he was fairystruck.

Patton refers to himself as "The World's Greatest Adventurer".

They are pompous and arrogant, but they successfully lead the diversion against the dark creatures allowing Grandpa's party to safely escape to the old manor. Broadhoof loses a duel to Patton Burgess. They join the force attacking the dark creatures in the battle at Kurisock's tar pit.
Kurisock
The demon Kurisock is one of the four known demons on the Fablehaven preserve. He is barely mentioned in book 2, but not a focal character until book 3. He is described as a demon more of shadow than substance. After the dragon prince Navarog was released, he found the revenant's talismanic nail that Seth pulled out and discarded. He gave the powerful nail to Kurisock, who inserted it into Ephira's tree. Then he merged with the tree. With the cursed nail in the tree, both Kurisock and Ephira's power were greatly enhanced, and together they caused the Shadow Plague.
