I am planning to tie my DH game together with the Yu'Vath. So far its been random missions as the game started with me just giving a demo without any real plan.

Im just wondering if my story contradicts any piece of fluff or if there was anything I could use about the Yu'Vath as I cant find much information.

The idea behind it is that Lady Solace of the Pilgrims of Hayte (see DotDG) is attempting to destabalise the sector by either bringing back the Yu'Vath or bringing back Haarlock. She is attempting to do both at once while also using her self as a distraction from her real goals.

My basic premise is that she knows where the Yu'Vath have been imprisoned by the Eldar after they were defeated in the Calixis sector (this is my story, not canon) she is working on how to bring them back but its just not as easy as that, she knows that should the Yu'Vath return now they will be easily twarted by the Imperium and may serve to strengthen the sector in face of adversity. To this end she has used Yu'Vath artifacts to corrupt an unknowing Xanthite inquisitor and has started spreading cults throughout the Imperium that when the time is right will destabalise the region. The cult leaders are given Yu'Vath artifacts that are shipped from the Kronos expanse and dispersed by a noble house on Cantus who are allies to the Inquisitor (after he rewarded them financialy). The Yu'Vath artifacts make the wearers subservient to their masters and in the absence of the Yu'Vath they make the wearer seek to convert populations to serve the Yu'Vath.

Is there anything that outrights contradicts this or any interesting bits of fluff that I could wieve in? What do you guys think of the general premise?

where does Haarlock tie into all of this?

Mostly just that im running the Haarlock games and in my game she was the one responable for them being abducted in tattered fates. She was controling the Beloved (who met a spectacularly grusome end when a bolt pistol blew him into the clock as it materialised). She knows that the PC's are tied into the events of the Haarlock legacy and has been testing them and drawing them out. In reality there is only one PC that can really be connected as he was the only one present at both The House of Dust and Ash and Tattered Fates. The character in question is a Cleric who lost the fire of his faith when his world was overrun by a Daemonic invasion. He has slowly begun to regain it and I hope he will not die before that.

To her Tattered Fates was simply a proving ground for the PC's to see how they dealt with the Haarlock legacy. She is now conflicted as she forsees that the players are important to the culmination of events yet she doesnt know if they will stop it or cause it to happen. What she doesnt know is that their fate is actually tied to hers so it is her involvement in the Haarlock legacy that is causeing theirs, their Inquisitor is also a long time opponent to Lady Solace and a powerful Divination psyker who has been attempting to find people who can fight Lady Solace and put them in a cell together. Some are there because they are genuinely connected and others because he thinks they are and others to fill in numbers or areas of expertise.

Their Inquisitor has recently found a connection between a minor heretical cult and a Rogue Trader, he has detected a connection between his acolyte cell and the cult so worried he is having them investigate one of the Rogue Traders contacts which is the Noble house on Cantus. The Rogue Trader had sold on a Yu'Vath artifact to someone else which caused them to try and create subserviant cult. The leader of the cult escaped so the Yu'Vath connection hasnt been made yet but others around him who were questioned brought up the Rogue Trader. To ensure that the Rogue Trader isnt spreading taint he is having them investigate House Ramio of Cantus with whom he has a legitimate and lucrative buisiness deal providing raw ores and materials from the Kronos expanse.

I like the concept of the Eldar imprisoning the Yu’Vath. If the Yu’Vath escape now, the Eldar might move to prevent this from happening. They could even ally themselves with the PCs or, more likely, use them as witless pawns in their great schemes.

Remember that Solomon Haarlock, upon charting the Calyx Expanse, came across ruins of long-gone civilizations. In the timeline it says: “He [Haarlock] also notes several worlds that he deems to mark out the territory, of a long dead greater civilisation, aeons old, and names their former realms a “Chalice of Great and Ancient Wickedness”.

This could very well be the Yu’Vath!

I considered that but the Yu'Vath were active in the Calyx expanse in that time, they were a thorne in the side of the crusade so they weren't a long dead civilisation at the time.

I thought the Eldar imprisoning them explained why they disappeared from the Kronos expanse as well. The Yu'Vath would normally have been able to stop the Eldar but they were wholey focused on fending of the Imperial crusade. When the Eldar imprisoned the ones in the Expanse they were no longer able to reinforce the ones in the Calyx expanse allowing Drusus to gain the upper hand and eventually wipe them out. I imagine that they were a threat to Eldar worlds and outposts in the Kronos expanse but until they were reduced and distracted enough by the Imperium they didnt have the resources to deal with them. I think the way I'll do it is that they are actually imprisoned them within their own warp based devices. These devices becoming the Halo artifacts, transforming the person with who they are bound to the ancient will off the Yu'Vath all though the Yu'Vath can never truely take over the person.

They are bound within the artifacts as long as the wraithbone dias upon which the binding rites were preformed is kept intact. The Dias itself is well hidden but after decades of searching and daemonic pacts Lady Solace has finally found it. Now she needs to ensure that the Calixis Sector is in a weakened state so that the return of the Yu'Vath is appropriately violent and catastrophic.

As a side note Im also having it so that the Eldar wiped out the Egarian domain after having been corrupted by the Yu'Vath as they posed a threat of allowing them to return.

Is it established canon that the Halo devices are a remnant of the Yu'vath?

When I read the fluff on Halo devices, I decided then and there that these devices are actually the receptacles, the artefacts in which the Yu'vath retreated to escape their enemies. They gave up their bodies and hid their souls in the devices, until such a day when they could recreate new bodies and rise again as a race.

As far as I know there is nothing about the origins of the Halo devices in the established canon.

The Dark Frontier/Forsaken Bounty web adventures make a link between one of the Halo Devices and the Yu'vath at least. There's nothing to say that they're exclusive to Yu'vath, but the link is definitely there.

Also, why would the Eldar imprison the Yu'vath instead of destroying them?

Resources mainly. Waging a full war against the Yu'Vath would have been dangerous and costly in Eldar lives. It was an oppertunity to get rid of the Yu'Vath without putting any Eldar lives at risk.
