When Syl first spoke to Kaladin, she took the form of a young woman, about a handspan tall, with an angular face and long flowing hair that faded to mist. She was formed of pale blues and whites and wore a flowing white dress that also faded to mist. However, her face, hands and feet were crisply distinct, and she had the bust and hips of a slender woman.
Although she glowed like an afterimage from looking at the sun, her form provided no real illumination.
Syl's figure blurs into a long white ribbon of blue-white light when she springs into the air, twisting and warping it like a strip of cloth caught in the wind.
This is her usual form, but she frequently takes others. She is normally only visible and audible to Kaladin. A few others, such as Rock, can see her, and others have seen her on occasion while Kaladin has been in action with his spear. She can also make herself to be seen by others, although she dislikes to do so.
She doesn't fly - she doesn't have wings - and doesn't bob in the air. She just stands in the air - on nothing - moving in unison with Kaladin, taking no notice of normal physical laws.
In Celebrant, Syl presents herself in an oversized poncho tied with a belt. On her head she wears a large, floppy hat, perhaps fearing to be recognized there, despite her illusory skin color provided her by Shallan.
She then says that she should've known the disguise wouldn't work. That she's obviously too beautiful and interesting to hide.
Syl is playful and upbeat - very child-like at times - and enjoys playing pranks on people. She cares for Kaladin both as a person and a Radiant. It greatly worries her when he thinks of vengeance as she sees how it twists him.
While she wants him to do what is always right and honorable she knows that this can't always happen. Syl does all she can to make Kaladin smile and raise his spirits; she wants him to be happy and to see the man he once was - a hero in her eyes.
She greatly dislikes showing herself to others apart from Kaladin. She believes that she is articulate and intelligent and reminds Kaladin of this whenever she feels he forgets.
However, she thinks she'd be an excellent mother. That she'd teach the little spren to fly, to coast the winds, to harass Kaladin.
According to Kaladin, Syl can be impenetrable with regard to the way in which she reasons things out.
Again, according to Kaladin, talking to her can be a surreal experience.
According to Syl, it is her solemn and important duty to bring happiness, light, and joy into his world when he's being a dour idiot. Which is most of the time.
She has no idea whether she is capable of creating baby spren (i.e., having children).
She's figured that since Kaladin doesn't seem inclined to do any learning himself, she should study.
Syl doesn't trust anyone who carries a Shardblade. Still, Kaladin tells her that it's not a mark of bad character to have bonded one of the weapons.
Even so, she replies that he should have someone swing around the corpse of his sisters by the feet, and that they'll see whether he considers it a 'mark of bad character' or not.
Syl has decided that it s her duty to make sure that Kaladin is not alone.
She can still be shockingly innocent - wide-eyed and excited about the world.
Syl was created by the Stormfather some time before the Recreance, along with a handful of other honorspren. Like the others of that group, she bonded a Knight Radiant: a kind elderly man. He died in his only battle, releasing her from the bond. Her inexperience with the bond resulted in her losing herself from his death and, in turn, she survived the Recreance.
She tells Kaladin that the Stormfather helped shape her. That he helped some spren find their voices. That he made some of them. That he made her.
Still, she slept for a thousand years before the Stormfather found her and brought her home, never letting her leave the city because of what had happened. Despite that, unable to ignore Kaladin calling out to her, she snuck out and gave her mind up to enter the Physical Realm.
The Way of Kings
Syl began to follow Kaladin when he was a squadleader in the army of Amaram, but first came to his attention as an anonymous windspren when he was a slave in the caravan of Tvlakv. At first she played pranks, but then began to ask him questions; unusual behavior for a spren. After he was sent to Bridge Four, and she woke him from an exhausted, depressed stupor following his first bridge run, he asked her whether she had a name. She appeared surprised that she did indeed; that it was Sylphrena, and that she also had a nickname, Syl.
Her abilities seemed to increase as their association continued. There was a significant increase in her intelligence and understanding when he assumed the leadership of Bridge Four. Eventually he came to value her company as a friend. She often gives Kaladin advice, and comes up with many suggestions and ideas to help Kaladin with various decisions. So far, she has shown herself to be an indispensable companion to Kaladin, even saving his life.
Syl also acted as a guardian to Kaladin as he recovered from his time left to die out in a highstorm, protecting him from deathspren by wielding a radiant blade of light. This may indicate an ability to inflict harm to other spren or a protective ability given by the bond she has with Kaladin.
She admits that Kaladin's Surgebinding powers are intricately connected to her transformation into a more "human-like" spren. She also reveals that, unlike initially believed, she is not a windspren but an honorspren.
When Kaladin remarks on Dalinar's Shardblade, Syl demonstrates a clear dislike for the sword, stating that he is far better without it.
Words of Radiance
Syl becomes increasingly more aware of her existence and purpose as an honorspren.
|“||"I am a god," Syl had said. "A little piece of one." ||”|
However, during highstorms, she becomes more spren-like.
After Kaladin breaks his oaths, Syl's bond with him becomes progressivly weaker until his fall into the chasm. Encouraged by the Stormfather, Kaladin believes that by forcing Syl to provide him with Stormlight during the fall, he killed her. However, when Kaladin stands up to Moash during the assassination attempt on Elhokar, Syl returns to him, claims him, and he speaks the Third Ideal of the Windrunners. In addition, she states that if Kaladin dies, she "goes stupid again". This serves as proof that she was once bonded to a Radiant, but he died (and did not break his oath) leaving Syl to become a pure honorspren again without truly dying like the spren of those Radiants that did break their oaths.
|“||"Everyone is connected, Kaladin. Everything is connected. I didn't know you then, but the winds did, and I am of the winds."
"The winds are of Honor," she said, laughing as if he'd said something ridiculous. "We are kindred blood."
"You don't have blood."
"And you don’t have an imagination, it appears."
–Syl to Kaladin
She tells him that there's another voice. One that is pure, with a song like tapped crystal, distant yet demanding ... then smiles, and zips away.
Later, when he tells her that it doesn't feel right wielding her like a weapon, that it feels strange because she's female, she informs him that some of his spears have been female.
Later still, she tells him that Dalinar thinks God isn't dead. Just that the Almighty - Honor - was never actually God. When Kaladin replies that she's part of Honor, and then asks her whether that offends her, she says that every child eventually realizes that her father isn't actually God.
While in Shadesmar in the city of Celebrant, Syl tells Kaladin that there might have been an enormous reward for her return to the honorspren from whom she previously snuck away. That this would be posted in basically every port in Shadesmar, with her description and some pictures. He tells her she's been forgiven, that the Stormfather had accepted her bond to him. That her siblings are watching Bridge Four, investigating potential bonds themselves. She tells him that this is kind of recent, and doubts she's been forgiven because the others on the Shattered Plains wouldn't talk to her. She thinks that they believe she's a disobedient child. That there's still an incredible reward in Stormlight to be given to the person that delivers her to the honorspren capital, Lasting Integrity.
After the firing of Ico's ship, at Azure's insistence, Syl starts running toward the majestic white and gold ship, which was slowly being pulled away from the docks. Throwing down her poncho and hat, she then screams up at the ship while running along the pier beside it. The vessel stops ponderously, handlers slowing its mandras. Three blue-white honorspren appear at the side, looking down with utter shock, saying "Sylphrena, the Ancient Daughter?"
The tactic works, a gangway drops and Syl scrambles up onto the ship, followed by the rest of her party. While a Fused did come after them, it stopped at the mouth of the alleyway, watching them board the ship. Honorspren, apparently, giving them pause. On board, Kaladin discovers that most of the sailors are those spren made of fog or mist. One of these ties Syl's arms together with rope. Kaladin tries to intervene, but Syl shakes her head.
Syl can hover without wings. She has the ability to follow Kaladin's every step exactly while hovering, which has always amazed Kaladin.
With some difficulty, she is able to lift and carry light, small objects such as leaves.
Once Kaladin has spoken the Third Ideal of the Windrunners and the Words have been accepted by the Stormfather, Syl is able to coalesce from silver mist in Kaladin's hand into a glowing, brilliant Shardblade with vivid blue light shining from the swirling patterns along its length.
In a later instance, when Syl coalesces into a Shardblade, she takes the shape of a sleek, beautiful sword with the symbol of the Windrunners prominent on the center, with lines sweeping off it toward the hilt - grooves in the metal that look like flowing tresses of hair.
|“||"I bind things, Kaladin. I am honorspren. Spirit of oaths. Of promises. And of nobility."||”|
–Syl to Kaladin while viewing the betrayal of Dalinar's army. 
|“||"I don't know, it just feels wrong to me. I hate it. I'm glad he got rid of it. Makes him a better man."||”|
–Syl to Kaladin about Dalinar's Shardblade.
|“||" ... I don't smash into things. I am an elegant and graceful weapon, stupid."||”|
