Yvraine was originally born on Craftworld Biel-Tan, which could explain where she got her fighting skills from. However, her first path was the Path of the Dancer. At some point, she found she had psychic ability, and thus she took the Path of the Seer, becoming a Warlock. However, she had a mercurial mood, and developed a bloodlust that led her to follow the path of the Warrior among the Dire Avengers.
After awhile, even this wasn't enough for her and she left Craftworld Biel-Tan as an Outcast and eventually became a famed Corsair leader. This continued for a time until a mutiny forced her, and those among her crew still loyal, to flee into the Webway. From here there was only one place to go; Commorragh. Here she made her way living and fighting in the slums before joining a Wych cult and then rising to become a Succubus under the patronage of Lady Malys. Unknown to her, the Exarch she had served under had become so devoted to her that he had shed his war mask and followed her to Commoragh by disguising himself as an Incubus (which is something they are not normally able to do, since Exarchs come into being when they become lost in their respective paths).
So yeah, she gets around. Even has a pretty boy or two chasing after her.
Yvraine's rebirth came about during a major gladiator match in Commorragh. It was here that Yvraine (aided by the patronage of Lady Malys) was to face off against Lelith Hesperax herself. To raise the stakes, they would be fighting among Wyches, Tyranids and other captives or monsters in a massive free for all. It was such a momentous event that Vect himself had arrived to watch (from the comfort of his private portable pyramid/command base/mansion).
The fight between Yvraine and Lelith was breathtaking, even the Harlequins in the audience were stunned. It was clear though that Lelith was toying with Yvraine and was clearly the better fighter... until Yvraine managed to get a cut on Lelith's forearm. However, this was a ruse that Lelith had allowed as part of her plan to draw out the fight and make it more entertaining for her patron, Asdrubael Vect. But the punch to the stomach that Yvraine dealt Lelith was not part of the plan. Yvraine got super pissed and entered berserk mode that caused Lelith to start giving ground and, after getting in a vicious stomp on Yvraine she led Yvraine to a pile of Tyranid corpses. In a nifty display of Just As Planned, Yvraine lost her footing after one of the corpses she was fighting on had a death spasm and Lelith used the opening to stab Yvraine through the sternum before darting off to a new opponent and leaving her for dead.
Despite her wound Yvraine fought, trying to not show weakness in the arena. But even her red attire couldn't hide the blood trailing down her chest. At one point she crossed paths with a priestess of Morai-Heg with needle-like blades. She proved surprisingly quick, even severing one of Yvraine's hands. In spite of her wounds, she still managed to take the priestess with her and ripped the priestess' throat out with her teeth.
That's right, Yvraine's so tough she kept fighting, even though she'd been STABBED IN THE CHEST AND LOST A HAND.
It was at this moment, while Yvraine was at the brink of death, that the newly born but weak Ynnead recognized Yvraine as one who had walked on both the Paths of the Eldar and the Paths of Damnation, and so revived her as his Emissary. Unfortunately, the psychic energy released in the process also broke Khaine's Gate open, flooding Commoragh with daemons and thoroughly humiliating Vect. Needless to say, Vect now wanted Yvraine dead (again) immediately. Trueborn from the Kabal of the Black Heart (looking to save face after Vect's retreat) headed towards Yvraine, seeking her death while her Wych Cult and the Visarch (who had been hiding in the crowd) rushed to aid her. Even Wyches from the Cult of Strife turned up, ordered by Lelith to help Yvraine for reasons of her own.
As they left the arena, Yvraine had another surprise. A ship, her flagship from her Corsair days, had returned to Commorragh. The crew took Yvraine, the Visarch and the survivors on before fleeing for the Webway. But Vect wasn't so easily thwarted. He sealed the Webway passages, and the ship got wedged in one. As Kabalites from the Kabal of the Black Heart tried to cut their way in, Yvraine loaded the Visarch along with as many crew and warriors as they could onto Raiders and Venoms, had them launched from the bridge, while the rest of the crew stayed behind willingly, sacrificing themselves to delay Vect's revenge, which involved rape and torture monsters and their tentacle beasts in the hope of preserve their people's hope for salvation (Nobledark in 40K, more common than you think).
Yvraine fled Commorragh with her old Exarch (who had since renamed himself the Visarch), the Incubus warriors he had become the leader of since he arrived in Commoragh, the survivors of her crew and several members of her Wych Cult. They wandered the Webway for a time, fleeing the Haemonculi cults and Kabalites Vect had sent after them. They met up with a group of Harlequins, who led them through the Webway and kept them one step ahead of Vect's agents.
Return to Biel-Tan
Accompanied by the newly-formed Ynnari, Yvraine returned to Biel-Tan, the Craftworld of her birth. However, not all eldar were happy to see the return of this prodigal daughter. This 'family reunion' ended with the fracturing of Biel-Tan.
Battle in the Webway
In the Webway, they were waylaid by the Prodigal Sons, Ahriman's Chaos Warband. In an astonishing display of power, Ahriman managed to teleport Yvraine, the Visarch and the Yncarne out of the Webway. The Tzeentchian assault on Ynnari forces including the trio, Harlequins, Dark Eldar and Eldrad was saved only by the timely intervention of Phoenix Lords led by Jain Zar.
Yvraine called out to Ahriman, saying she had "what he was seeking". To prove her point, Yvraine used her powers to restore a dozen Rubric Marines to their former selves. Overcome with emotion, Ahriman brought back Yvraine, the Visarch and the Yncarne. However, to take him from the battle, Yvraine then had a Wraithknight smash a hole in the Webway, sucking those recovered Rubric Marines into the Warp. Horrified, Ahriman fled after them on a Disc of Tzeentch.
In the battle both the Yncarne and the Phoenix Lords went MIA. Yvraine would later show the ability to summon the Yncarne again, so long as there was enough death happening in the immediate area.
A Desperate Alliance
At this point the Ynnari joined together to enact another desperate plan: Eldrad had forseen that the Eldar's and the Imperium's fates were joined. For the Eldar to survive they would have to ally with the Imperium, this time for real.
To facilitate this, they picked up the survivors from the fall of Cadia (minus Creed, who had already been taken by Trazyn). Then, after a good word from Cawl, Celestine and Greyfax to explain their intentions, they headed to Macragge. There, Yvraine and Cawl worked together to heal Roboute Guilliman of his poison and bring him back to life.
After promising an alliance, the Eldar and the forces of the Imperium parted ways, with Guilliman thanking Yvraine for helping him and Yvraine giving Guilliman a sincere caution and no stereotypical Eldar dickery (something quite a few shippers have seized on, though this would be more ironic than Taldeer and LIIVI, given that Yvraine is the herald of a god and Roboute is implied to despise religion, though this is a combo of the Imperial Truth creed and Roboute's reaction to the Ecclesiarchy worshiping Big E).
Hand of Darkness
Whilst the Plague Wars were raging in Ultramar it came to the attention of Guilliman that Mortarion was using an artifact known as the Hand of Darkness to spread diseases (yes, the same one the Imperium "lost" in the 12th Black Crusade). Knowing that the artifact was well-known to the Eldar and that they had a common interest in seeing it out of Chaos' hands, Guilliman requested the aid of Eldrad and Yvraine to retrieve it, having Varro Tigurius supply the Eldar with its location as the Imperium had been able to locate it whilst the Eldar had not. Armed with the knowledge that the Hand lay within the domain of Nurgle himself, Yvraine went to the Black Library in order to find a method to safely enter it. After battling against the Thousand Sons, facing off against Ahriman again, and overcoming a test along with the Visarch, Yvraine gained access to something known as the Rose of Isha and, using it, created a safe passage into the Eye of Terror. Following this path she and her party located the Hand of Darkness, slew its guardian, and fled with it.
After escaping with the Hand of Darkness the White Seers of the Black Library offered to take it and destroy it, claiming that no good could come from using Chaos Artefacts. Clearly they had never met Logan Grimnar, Marneus Calgar or Kaldor Draigo who have all, several times, used Chaos Artefacts for good. However, Yvraine refused them, insisting that she had to return the Hand of Darkness to Guilliman.
Shortly after giving the Hand of Darkness to Eldrad so he can send it to Guilliman, Yvraine was contacted by Iyanna Arienal, who had heard that a long-lost Craftworld known as Zaisuthra appeared to have returned after it had left the galaxy. Along with an Iyanden Wraithhost, the Ynnari went to investigate the craftworld, mainly because legend had it that it contained a webway portal to the Tomb of Eldanesh, which Yvraine suspected could be the location of the final Cronesword.
Although the inhabitants of the Craftworld were friendly at first, it was eventually revealed that it was infected by Genestealers: the Craftworld had left the galaxy before the Infinity Circuit technology could be spread and the ancestors of the Craftworld's inhabitants chose to submit to the Broodmind in order to preserve their souls from Slaanesh. As the hybrids that now constituted the Craftworld's population were running out of resources, their plan was to use Iyanna Arienal to spread their infection to Iyanden, manipulating her into joining the Broodmind by preying on her desire for a family (her original family being killed and their soulstones shattered when a torpedo struck Iyanden - and distant relatives of said family residing in Zaisuthra). Their plan turned against them when Yvraine and Iyanna were able to summon the Yncarne into the Broodmind, who then proceeded to devour the souls of most of the Craftworld and slay the Genestealer Patriarch (which had somehow absorbed the power of the Craftworld's Avatar) leading the hybrids.
Yvraine then took the gate to the Tomb of Eldanesh. Finding themselves in what appeared to be the Eldar homeworld, thought lost during the War in Heaven, they discovered that the tomb did not house the Cronesword but instead the Warshard, the most powerful Avatar of Khaine of them all, who wielded Anaris itself and whose presence was enough to drive most of the Ynnari forces into a team-killing frenzy. It was defeated, but at the cost of a third of the Ynnari's forces. Meliniel, a Biel-Tan Autarch who essentially acts as Yvraine's second-in-command, was able to bind the Warshard into himself using a gem made of Eldanesh's blood and transform into Khaine's Avatar at will, so now the Ynnari have their very own Avatar of Khaine. Shame you can't have one in an Ynnari army though. (¿Porque GeeDubs?) Plus, it cost them a third of their forces.
Though Yvraine does not know it, the Visarch is actually her former Exarch and Mentor who, possibly, has romantic feelings for her. Despite this, and despite being her self-appointed bodyguard, in their actual interactions and discussion the two get along very poorly and are prone to snapping at each other. They have three times already drawn their swords on each other and threatened to kill each other, and only two of those times were they under the influence of Daemons. The Visarch strongly dislikes what he calls Yvraine acting as Guilliman's lapdog and pet, accusing her in the Gardens of Nurgle of being nothing more than a minion of the Imperium. Yvraine ...doesn't have much to say against this as she fears he is right, but is angered by it nonetheless. It says a lot about the Eldar that helping save an ally who asked for help causes them to think this way. Clearly they don’t actually understand what an alliance is. The whole “we help each other” thing seems rather lost on them. Perhaps Guilliman’s charisma and sheer presence is enough for now. Besides, they should know by now that doing what a Primarch says is a wonderful way to pretty much always win at everything.
In any case, believing that stopping the spread and creation of interstellar undead plagues is being a "lapdog" is...oh, God-Emperor that is so stupid. Then again it's not like the 'alliance' has stopped the Imperium and Eldar from killing each other across the galaxy (between Imperium and Eldar, not Imperium and Ynnari generally except by accident since neither side is big on talking and co-ordinating with each other), and the whole "awakening of Ynnead" bit was almost halted by the uninvited Deathwatch (because it would've killed billions of people via orbital bombardment of meteors by destroying the crystal moon the ritual was being performed on).
Time will tell if the two can forge a closer working relationship but, for the moment at least, both of Ynnead's foremost servants are far from friendly with each other. The "Belligerent Sexual Tension" trope anyone?
Warhammer Fantasy Battle
Yes, she had a fantasy counter part, being the daughter of Aenarion (the first phoenix king of High Elves) and the second Everqueen after her mother Astarielle the first Everqueen. Like her brother Morelion (who is the ancestor of Tyrion and Teclis), she is the ancestor to Alarielle, the current Everqueen.
