“It's okay, we could all use a little more weird in our lives.”

—Fitz Vacker, in Book 2: Exile

Fitzroy Avery Vacker (''Fits Vack-er) known as "Wonderboy" as Dex calls him, Fitzy, and Fitzter as Keefe calls him is a seventeen-year-old elf, as of the end of Lodestar. He is one of the many belonging to the Vacker family and lives in Everglen. He was a skilled Level Four prodigy at Foxfire, a prestigious elf school in Book 1. In Lodestar, he became a Level Five Prodigy. It was officially revealed by Shannon Messenger that Fitz's name is short for Fitzroy. Along with his sister Biana Vacker, he is said to be the first Vacker to attend Exillium, during his exile period in Neverseen. He joins the Black Swan.

Fitzroy means "son of the king/seeker of wisdom". Avery means elf or counselor or ruler of the elves.

Physical AppearanceEdit

Fitz has light teal blue eyes and dark hair. Sophie Foster mentions he looks like a younger version of Alden. He is also often described to have a "movie star-worthy smile."

He is also much taller than Sophie, as noted in Everblaze, saying at Sophie is even shorter than Biana and she replies by pointing out that Biana always wears heels.

Abilities Edit


Fitz Is a Telepath, the youngest to manifest before his sister broke his record. He is Sophie's cognate, allowing the two to increase their abilities when working together. He has much potential, and is proud of his talent.  

Biography Edit

Fitz has one little sister and one older brother, Biana, and Alvar. His best friend is Keefe Sencen. He and Keefe grew apart when Keefe joined the Neverseen, but later, the relationship slowly mended itself. His parents are Alden and Della Vacker.  

Fitz was the second-youngest elf to get his nexus off (after his sister, Biana, the youngest) and the third youngest ever to manifest an ability, besides Sophie and Dex. He used to be the Splotching champion before Sophie beat him by using a Brain Push.

When originally creating the first version of Keeper Of The Lost Cities, Shannon Messenger created Fitz as the first character. He was originally created to look for Sophie and quickly find out she's an elf. This was not the final product, seeing as it a short story with an ending of Sophie finding out she is an elf, and now there is an entire series.

Involvement Edit

Book 1: Keeper of the Lost Cities Edit

In Keeper of the Lost Cities, Fitz is the one who located and took Sophie to the Elvin world. Fitz was also the one Sophie called out to when she and Dex were kidnapped by the Neverseen. Along with Keefe and Biana, he also helped find Sophie by the Four Seasons Tree.

Book 2: Exile Edit

In Exile, Fitz accuses Sophie of being damaged and the reason why his father, Alden, ends up with a broken mind after taking Sophie with him to Exile to perform a memory break on Fintan. Fitz and Sophie's friendship breaks until Sophie comes back to retrieve Alden's mind after she has healed from her own problem. Before Sophie heals Alden, Fitz takes her aside and apologizes for his rude behavior to her. He said that Keefe told him all about what happened the day before, which made him realize how his actions and words caused Sophie to be in the Neverseen's reach. He also explained that his anger was a way of coping with the grief of losing his father. Fitz also said that, whether or not Sophie could heal Alden, he would stop blaming Sophie for Alden's loss. Sophie manages to heal Alden in the end.

Book 3: Everblaze Edit

In Everblaze, Fitz and Sophie have telepathy lessons together and learn to truly trust each other in order to heal Fintan's broken mind. They have trust exercises which consist of sharing secrets about themselves that they haven't ever told anyone else. In the end, their trust is so strong that Sophie lets Fitz into her impenetrable mind. One of the secrets Fitz shares with Sophie is Mr. Snuggles, a sparkly red dragon given to him by Elwin to help him cope with the grief of losing his father when Alden's mind was broken. Fitz is very patient throughout this process even though Sophie keeps locking him out of her mind in instinctual self-protection. Together they develop code words to keep what they are doing during the mind-healing a secret from Fintan. They perform the healing, but the whole process is a disaster because Fintan sparks Everblaze. Fitz saves Sophie from burning by yanking her away from Fintan; Sophie then teleports Fitz and Oralie away from the burning tower. Together Sophie and Fitz collect Quintessence (after a special moment under the stars) to create Frissyn and stop the Everblaze.

Book 4: Neverseen Edit

During Neverseen, Fitz joins the Black Swan along with Keefe, Dex, Biana, and Sophie (as well as his mother, Della Vacker, unbeknownst to him). There he and Sophie work on becoming Cognates. They finally tried to go save Prentice in Exile. Fitz gets seriously injured in Exile by being thrown back on an arthropleura's antennae after throwing one of Dex's gadgets in the hall to stop it from exploding from one of the councillor's lightning. Dex took him back to the Black Swan's hideout to get treated by Physic, the Black Swans doctor. Fitz took a week to heal by drinking "vile tea". When Keefe visited his room he found Fitz cuddling with Mr. Snuggles. They were then sent to Exillium. Fitz got off of the Arch of Dividing by doing what Sophie called "a gold medal worthy flip" to the top of the arch, then untying the knot and levitating to the ground. Fitz went with Sophie to save a gnome that was infected by the plague. He and Sophie tried to read King Dimitar's mind. Being the natural gentleman that he is, Fitz let Linh lean on him after she lifted the river to get into Ravagog. Fitz backed away from Alvar when he knew he was with the Neverseen. Fitz also cried when Keefe joined the Neverseen.

Book 5: Lodestar Edit

At the beginning of Lodestar, Fitz gave Sophie two Cognate rings, telling her his full name was Fitzroy Avery Vacker. Fitz said he didn't trust Keefe after he left for the Neverseen. Fitz and Sophie went to try to read a few more things out of Prentice's mind. Fitz, Biana, Sophie, Dex, Linh, Tam, and their bodyguards went to Keefe's room to see if there was anything related to the Neverseen, playing Boys vs. Girls to see who could find more things. The girls won, and Fitz noted that he owes Sophie a favor. He said if Sophie doesn't use the favor in a month it becomes his. They find a leaping crystal in an envelope that Keefe had not seen yet. It leaped them to Paris.  

Fitz, Biana, and Sophie had a sleepover at Dex's house. Fitz and Sophie visit Wylie to read his mind. Sophie and Fitz leap to Eternalia and ask Oralie to help them visit Gethen. After coming back, they found a note from Keefe on Sophie's bed. It had a leaping crystal in it and said: "meet now". The crystal took them to a beach. Fitz didn't seem very happy seeing Keefe. Alden, Sandor, Grizel, and Grady eventually found them and Keefe leaped away. Alden banned Fitz from leaving the house until he finished his matchmaking packet, but he finished right away the next day. After the summit, Sophie sent Fitz a message saying that she was okay. After the destruction, Fitz visited Sophie regularly. Near the end of Lodestar, Fitz reminded Sophie of the favor she owed him, but recommend that they "skip the talking." When Sophie and Fitz were about to kiss, Keefe interrupted. They then went to the Fosters' new house with Alden, only to find Sophie's little sister Amy

Book 6: Nightfall Edit

Throughout the book, Fitz gives Sophie little gifts.

Book 7: Flashback Edit

Fitz threatens to leave Everglen because Alvar Vacker will be living there. Sophie convinces him not to. While Sophie convinces him not to they are attacked by the Neverseen. Umber attacks them with shadowflux leaving echoes in them. Fitz's echoes are in his heart effecting his emotions. He spends time in the healing center with Sophie. Much of which he spends unconscious snuggling with Mr. Snuggles. After Fitz begs Sophie to try once more to search Alvar's mind to be sure his memories are gone, Sophie agrees to cognate train and check Alvar's mind with him. After they search Alvar's mind and fail Fitz brings Sophie to the overide for Everglen and shows her how to use it. Later they go to the reception hall and Fitz confesses wanting Sophie to be the only one on his matchmaking list and Sophie reveals to Fitz that she's had a crush on Fitz since the first time she met him. When Fitz was about to kiss her, they were interrupted by Silveny's call for help. Fitz repeatedly levitates Sophie and her bodyguard Tarina (sometimes with the help of Timkin Heks or Tam) enabling her to teleport to various locations in an effort to help Silveny. Fitz also provides emotional support for Sophie.

In the Flashback Barnes and Noble Exclusive version Fitz has a short story in his point of view. The short story is him and Biana talking. Biana appears to know about this crush and it's revealed he first realized he had a crush on Sophie when he was impaled by the Arthropleura.

Relationships Edit

Sophie is Fitz's crush, later to be revealed in book 7; they end up possibly being in a relationship.

Mr. Snuggles is Fitz's sparkly red stuffed dragon he sleeps with. Mr. Snuggles was given to Fitz by Elwin (known for his crazy gifts) after his father suffered from a broken mind. Needing the comfort then, Fitz began to rely on his stuffed pal which he can no longer sleep without. telling no one except for Sophie, though Keefe finds out about it in Neverseen. Every time Fitz looks or thinks about Mr. Snuggles, he's reminded of Sophie.

Alden is Fitz's father. They both have a very strong accent and look alike. When Alden's mind is broken in Exile, Fitz gets really angry. It seems Fitz is very close to his father and respects him, for he always knows that Sophie will call Alden if she is in trouble, and cares about him a lot even if it's through protectiveness caused anger. Fitz gets aggressive toward everyone except immediate family when Alden's mind breaks and blames everyone for it. Eventually, Alden's mind is healed by Sophie, and Fitz stops acting aggressively. Alden cuts off Sophie, Dex, Keefe, Biana, and Fitz's registry pendants in Neverseen, and allows them to join the Black Swan. Alden seems to have an understanding of Fitz's need to help Sophie on her missions and allows him to go with her willingly.

Della is Fitz's mother. When Sophie and Fitz fall from a tree while playing Base Quest, she helps them treat their wounds and bruises. She cares deeply about Fitz as well as her other two children. After Sophie brings Fitz back from being lost, Della goes and hugs him tightly. Della also goes with Sophie, Fitz, Dex, Keefe and Biana to join the Black Swan, however, none of them know. She becomes a powerful asset to the Black Swan in Neverseen.

Alvar is Fitz's older brother. He stays and helps out a lot after Alden's mind is broken.When Fitz apologizes to Sophie, Alvar shows up to tell them that the Council is ready for Sophie to heal Alden's mind. Alvar was also Fitz's role model. When Alvar is helping the Black Swan destroy Ravagog, he proves to be a traitor, who was working with the Neverseen the entire time. When the Vacker's find out, they are distraught that their son/brother was lying their whole lives, and the family goes through a time of anger as well as grief.

In Nightfall, Alvar's memory was completely wiped away. Fitz never forgave Alvar for his treachery, despite how much Alvar insisted in Flashback he was never going to be that person again. Alvar got his memory back later on in Flashback and immediately rejoined the Neverseen. Fitz continues to hate Alvar, and almost killed him in Flashback.

Biana is Fitz's little sister. She cheers him on when he is splotching against Sophie (most likely because she didn't like Sophie in the first book). He is shown to be very protective over her. She is usually seen playing Base Quest with Sophie, Fitz, and Keefe. In Exile, they are talking to each other in the kitchen and Fitz volunteers to tell Biana the news about Alden's broken mind. The siblings tease each other and have a close relationship.

Keefe is Fitz's best friend. They often play Base Quest with Biana and Sophie and they play Bramble against each other. He tells Fitz about what happened to Sophie when Fitz was angry at her about Alden's broken mind, which causes Fitz to regret his words and actions towards Sophie and he humbly apologizes. Keefe often teases Fitz about Mr. Snuggles. After Keefe goes to the Neverseen, Fitz stops trusting him and their friendship turns problematic. During cognate training with Sophie, Keefe does something that makes Fitz jealous, and that day does not end well for them. Fitz was obviously angry at Keefe, especially when they met with Sophie, where he teased them. Fitz also started to dislike Keefe a bit more after interrupting a moment when he and Sophie were about to kiss. Near the end of Lodestar, they both go to the Forbidden Cities, but they both did it just for Sophie. Also in Lodestar, Tam says that Sophie and Keefe are close and Fitz disagreed. When Sophie communicates with Keefe several times in Lodestar, Fitz shows jealousy and disappointment. After Keefe got back their relationship was strained for many reasons one being Fitz felt that Keefe might betray them again, but it might also hint that Fitz was also jealous of the relationship Keefe has with Sophie. And slowly, in Lodestar and Nightfall, it seems that their relationship might be falling apart.

Dex used to not like because of the Vacker's being the noblest family in the Lost Cities, while Dex is a child of a “bad match”. Evidently, also because Dex is well aware that Sophie could possibly have feelings for Fitz, and most likely does. When they are first in a situation together, although they seem to have met before, Dex says he knows Fitz, but Fitz says he doesn't know Dex, making the conversation extremely awkward. He calls Dex "Deck", by accident. When Sophie is mad because she found out Biana was forced to be her friend, Fitz, wanting to make peace, asks Dex to go talk to her. Dex repeatedly calls Fitz "Wonderboy" in a jealous way. When Fitz and Sophie are splotching he cheers for Sophie. He is shown to be happy when Fitz got slammed into the wall much harder than Sophie. Dex also got upset when he found out she would be having telepathy training with Fitz because he feels that Fitz is hogging Sophie. Finally, though, in Book 4, Dex is the one who leaps Fitz back to Physic, blaming himself for Fitz's injury. They have a conversation, get over their prejudices, and become friends.

Fitz meets Linh after being banished to Exillium. The first time he sees her using her hydrokinesis, he literally says "Wow."  After she falls while they are escaping Ravagog, Fitz holds her because he's a gentleman, and carries her because Linh's twin, Tam, couldn't hold her at that moment, and was fairly tired himself. In Lodestar, he says "Wow" every time she does something with her amazing, and rare, ability. It is unknown if Fitz actually likes her or is just impressed with Linh's ability. In Nightfall, Linh impresses Fitz many times with her powerful hydrokinetic abilities. When Linh suggested that they could work together Fitz seemed happy and Linh blushed. Linh possibly had a crush on Fitz, maybe because of the same reason Sophie does, that he was good-looking, or because of other reasons. In the book it also reveals that Linh was shy, so possibly it was her personality.

Character Bio by Shannon Messenger Edit

Fitz is the golden boy from the famously important family who spent years secretly helping his dad search for Sophie in the human world. He’s a talented Telepath—though not *quite* as powerful as Sophie is. He’s a loyal brother, a model prodigy, and tends to earn his nickname, “Wonderboy” (despite the fact that Dex meant the name sarcastically). And even though he’s two grade levels ahead of Sophie, Fitz cares about her more than she knows (more than he knows, honestly). Maybe it’s because he saw how hard it was for Sophie to leave her human life behind, or because she’s close in age to his younger sister, but he feels a special connection with Sophie, and does everything he can to keep her happy and safe.[5]


  1. This is what he is called by his friends pre-keeper
  2. He is sometimes called this
  3. Dex made this nickname for him
  4. Keefe is known to have called him this before.
