The Harlequins offer to guide Yvraine to a destination she knows well. Craftworld Biel-Tan.

You see, Yvraine was born on Biel-Tan. She walked the Path of the Performer first, dazzling with her displays of acrobatics. But then she felt the call of violence and went on the Path of the Warrior, but eventually not even the fiercest of battle could sate her spirit. So she tried the Path of the Warlock for a bit, but that wasn't quite right for her either. So she became an Outcast, rising up to become a famed Corsair admiral before a mutiny caused her to flee to the arenas of Commorragh. And here she is now, the Prodigal Daughter returning to Biel-Tan as a new force that could change the fate of Biel-Tan and the Eldar forever. Biel-Tan, as I’m sure you’re all aware, has violent and vengeful ambition to restore to the Eldar to its former glory. They think that the Exodite Eldar are the true hope of the Eldar, and will prosecute anything threatening one of their Maiden Worlds with extreme force hence their reputation as the most militant of the Craftworlders. Most other Craftworlds look on this as a delusional ideal though - the ability to restore the Maiden Worlds to the former glory of the Eldar Empire has long passed. But not everyone thinks that way, a certain Ulthwe High-Farseer and a troupe of Harlequins among them. Eldrad has forseen the coming of Ynnead's ascension in the form of Yvraine and the ambitions of Biel-Tan could be a perfect platform to make this happen and the Harlequins of the Midnight Sorrow have already worded up Biel-Tan about an arrival of a ominous nature. The Biel-Tan Autarch Melineil consults with his sister, Farseer Lathriel - in her divinations she sees a fork in the road. One path leads to Rhana Dandra (the end of days) and the other leads to darkness with the sound of a mourning bell ringing. Could the prophecies of the Seventh Way (the one where the Eldar don't have to all die for Ynnead to awaken) be true? One other small problem though, unknown to the Eldar - The Masque of Slaanesh is kinda keen on getting inside Biel-Tan and feasting on their tasty souls, especially because she senses Yvraine will end up there. And she's got a plan.

There's a backdoor into Biel-Tan, from a Maiden World called Ursulia. It's sealed and all that, but the Masque reckons she knows how to crack it. A sudden Warp Storm has popped up over Usulia, wreaking havoc through the Exodites living there. Also, the massive Demonic Invasion that the Masque organised, made up of a grand promenade of Slaanesh demons... and a grand battalion of Khorne Demons. Wait what? Khorne and Slaanesh, like really, really hate each other! Lucky for the Masque though, she rolled really well on her Charisma at character generation and has like a Persuasion check of +30. The wards on the portal from Ursulia to Biel-Tan are too strong for her to break, but can they stop SKARBRAND?!?! Let's find out. She goes to talk to Skarbard with an offer of alliance, but Skarbrand aint interested in anything but Slaughter and Carnage. He goes to chop her into little pieces, but also lucky for the Masque she also rolled really high on Dexterity and has an AC of like 30 too. Eventually Skarbrand gets bored that she's not being dead, and she starts spinning a story of how they're not all that different from each other, both being exiled from their God and all that, and maybe they could have a friendly wager on who can kill the most Eldar on some random Maiden World. Natural 20 rolled on the Persuasion check it seems, because Skarbrand's ire is raised just enough to get him to agree to the wager (as if he's gonna let a puny Slannesh girl beat him!), but not enough that he flies into a rage and kills her on the spot. So off to Usulia they go, and the killing begins.

Biel-Tan aren't about to let one of their precious Maiden Worlds go down, so they launch a counter-assault with Autarch Melinial leading it personally. The battle rages back and forth, massed demon charges vs lightning strikes of Eldar. The Masque and Skarbrard are up near the portal – the Masque’s plan is to lure the Eldar up to the portal and set Skarbrand loose and in his rage he’ll destroy the wards on the portal. What could go wrong? Well the Eldar don't take the bait initially, and Skarbrand is in danger of being lured away himself. Not good! So the Masque jumps up on the Portal in full view of the battle and starts guzzling spirit stones off some Warlocks she's killed like they're oysters. Melinial is infuriated by the Masque's brazen feasting of Eldar souls, and directs all his forces towards where the Masque and Skarbrand are at the portal. The Eldar unleash a devastating amount of firepower, mainly at Skarbrand since he's a huge censored.gif-off Bloodthirster after all, and manage to kill almost everything around him (except for the Masque) whilst also putting a fair bit of hurt on him. Skarbrand gets extraordinarily pissed that he's gonna die before he can even get to do anything, and looks around for something to smash... and the only thing he can see nearby is The Masque dancing on top of the portal. So he directs a big SKARBRAND SMASH! at her... but she jumps out of the way, and he cleaves through the wards on the portal instead. Meliniel watches in horror as the Masque and a whole swathe of Slaanesh demons dissapear into the Webway, enroute to Biel-Tan. Unfortunately Skarbrand is blocking his way, preventing him from pursuing. Skarbrand eventually realises The Masque has bailed on him through the portal, and he gets really angry (they had a wager!!!) so he jumps through the portal too. Demons are swarming through the portal now, and Melinel is forced to destroy the portal to stop even more getting through to Biel-Tan (though obviously cutting himself off from reinforcing). He sends a psychic warning off to his sister to ready the defences.

Lathriel has the defences organised - all ways into Biel-Tan are sealed off except for the main portal at the back of the Craftworld, which is put under heavy guard to destroy it if necessary. Drastic steps, but better than letting the Craftworld get overrun. The defenders wait - everything looks clear so far - and a scout ship returns from monitoring the advance of the Demons through the webway. No-one notices The Masque clinging to the bottom... ah the old classics. She slips off into the Craftworld, hypnotising anyone who crosses her path which allows Demonettes to possess their bodies. Back at the main gate, the bulk of the Demon forces have arrived led by Skarbrand. He bursts through the portal, carving through the Eldar defences... but the Avatar of Khaine has been roused and they slam into close combat. Farseer Lathriel rushes forward to seal the portal before more demons get through, and when she turns around both Skarbrand and the Avatar have obliterated each other. Meanwhile The Masque has set herself up in the Avatar's (empty) throne, and is summoning more and more Demonettes and preparing a ritual. Some Howling Banshees come across her, but quickly fall under The Masque's hypnotic spell and then Jain Zar shows up. The Masque tries to hypnotise her, to no avail, and Jain Zar impales the Masque upon the Avatar's Throne... but not before the Masque is able to dig her rune-inscribed claws into the Wraithbone surrounding the throne and breaches the Infinity Circuit. Oh censored.gif. The Masque and her Handmaidens are transported inside the Infinity Circuit, bypassing all its defences. Biel-Tan is being destroyed from the inside.

With all routes into the Craftworld now sealed off, Jain Zar leads the counter-attack against the remaining Demons. Yvraine and her group of Dark Eldar and Harlequin guide had managed to get through the Webway Portal just before it was sealed. They're not exactly greeted with open arms by the Biel-Tan warriors - a group of Commarragh warriors right on the heels of a demonic invasion? Sounds suss. But Yvraine helps fight off a huge group of Demonettes that rush in, and a cautious parley is struck. The rest of demons (well the ones physically running around anyway) are mopped up and a War Council is quickly convened, as the very wraithbone structure of the craftworld beings to grey and wither and die around them from the demons still inside the infinity circuit. What the hell can they do? The Spiritseers are frantically running around, transferring souls into Wraith Constructs before they are destroyed in the Infinity Circuit, but even then that will be all for naught if the Craftworld just falls apart around them. Yvraine tries to speak up, but she is shouted down. She abandoned them before, and has now brought Dark Eldar here - why should the listen to her? But Lathriel speaks up for her - maybe Yvraine is the Opener of the Seventh Way? That gets the Autarchs attention, as it’s the first bit of hope they're able to hold onto. Jain Zar also steps up to bat for Yvraine. So Yvraine speaks.

Yvraine tells the Biel-Tan she is the emissary of a new deity, that Ynnead is awakening. She tells them that the Seventh Path is indeed real; that Ynnead can be fully awakened without all the Eldar dying. She tells them that his sentience can be focussed from 5 enchanted bones, each a finger from Morai-Heg's severed hand. Vaul fashioned these bones into blades, and together they can awaken a god. She raises her blade Kha-vir, one of the Crone Swords, to prove her point. There is another Crone Sword aboard Biel-Tan, Asu-var, and she intends to claim it but in doing so the Craftworld’s fate will be sealed. This doesn’t go down too well amongst the Biel-Tani and some step forward to try to stop Yvraine. Jain Zar and the Visarch both step in to defend her, as Yvraine reaches into the Wraithbone structure as if it were a pool of water and draws forth a Greatblade. This sends cataclysmic shockwaves through the Craftworld, shattering spires and wreaking havoc, millions of souls in the Infinity Circuit being destroyed. “Arise!” shouts Yvraine, as a terrible form of ‘twisted bone and shimmering souls’ bursts forth from the wraithbone. Yncarne, the Avatar of Ynnead, had arisen.

The shockwave of the Yncarne’s creation was a violent process. The warp roiled and buckled, a hundred new rifts opening up. Whole sections of the Craftworld split apart, revealing the skeletal framework of the craftworld. One good thing though, the Demons running loose in the Infinity Circuit were utterly annihilated. Some Biel-Tani saw Yvraine as a threat, some trickery of Slaanesh come to destroy their home and attacked, but Yvraine had given the Visarch the sword she’d just pulled – Asu-var – and none stood long against him. The Farseer’s managed to calm things down, and direct all efforts into saving as many souls from the infinity circuits as possible. Curiously, Yvraine and her followers were able to do this too, despite not being Spiritseers. Accusing them of soul theft, some Biel-Tani attempted to stop them but where in turn stopped by Harlequins. “They are the Ynnari,” the Harlequins would say, “Reborn of Ynnead. Your long-dead ancestors go with them willingly.”

With the immediate threat of the Demon invasion over, the Bonesingers set to work to try and repair the Craftworld. It would take centuries of work though, and currently the Craftworld was effectively dead in the water, surrounded by Warp Rifts and all access into the Webway sealed off. Yvraine was uncertain – how where they going to get out of this one? The answer would come from Ulthwe. Ynneads awakening in the form of his Avatar had sent psychic ripples across the galaxy. The Seers of Ulthwe saw what had happened in Biel-Tan most clearly, and Eldrad demanded that the Yvraine and her Reborn be brought to Ulthwe asap. How? Use the psychic energy of the crystal seers on Ulthwe to form a channel directly through the warp from Biel-Tan to Ulthwe. Alot of the Seers were uneasy about this – to break the ancient revered seers from the infinity circuit to be used as mere tools in a ritual? Sacrilege! But Eldrad pressed on with his gamble – a single mistake could suck the entire craftworld into the warp – but they succeeded and a stable and calm passage was opened. The Reborn on Biel-Tan stepped through, led by the Yncarne, and the translocation of the Reborn through the warp sent yet more shockwaves through the warp, ripping open Gellar Fields of Imperial Ships hundreds of light years away, and even distorting the light of the Astronomican. Thousands of human lives were lost, but the Eldar would gladly pay a million more.

Biel-Tan gets invaded by Slaaneshi daemons. Biel-Tan is badly damaged and the Masque breaches the Infinity Circuit. The allied Eldar and Dark Eldar fight away the daemons. Yncarne, the Avatar of Ynnead, gets summoned from the damaged Infinity Circuit of the craftworld.
