I wrote this "in-character" message to my Dark Heresy Players after their last few missions. Despite my grousing about the Dark Heresy rules, I like the setting quite a bit. Slight spoilers for a few of the published Dark Heresy adventures.

Transcript of Throne Agent debriefing by Inquisitor Globus Vaarack
"I sent you on a simple mission to recover and investigate an artifact on Barasapine. In this course of your investigation you AWOKE A TITAN which proceeded to destroy much of the city of Kephistron Altis! You report that this all occurred during a battle with a Greater Daemon of the ruinous powers. Then you send an astropathic communique to me saying you have vital eyes-only information to share. I dispatched a Rouge Trader vessel to retrieve you. On it's return trip this vessel was destroyed along with an Ecclesiarchy battle barge. It is unclear at this time whether these two ships were enaged in a battle or were destroyed by an outside force. What is known is that you and the remaining crews of both ships crashed on the Agri-world of Secticus IV. On Secticus IV, you encountered a xeno-form (XREF: NECRON) previously unknown is this sector. By rallying the remaining crews and the colonists, your cadre managed to fight off the xenos and send a distress call. (XREF Deathwatch kill team dispatched to Secticus IV) A nearby Ecclesiarchy ship responded and again you reported to me that you were en-route to Scintilla.
This ship never reached Scintilla. I assumed you and you cadre were lost. Months later, you turn up on Quaddis claiming you had been captured by the Beast House. On Quaddis, you witnessed the death of Inquisitor Karkalla and terminated an attempt by the Pilgrims of Hayte to take control of the Haarlock legacy. When you contacted me from Quaddis, I wasn't taking any chances, which is why I am here now.
The information you have brought me is very troubling. If Arch-Cardinal Ignato is a heretic, it could mean sector-wide unrest. Also, your discoveries on Quadddis point to the return of Haarlock himself. That old devil coming out of hiding may be worse than anything else you've discovered.
My question for you now is Where do you go from here? After Harlock or Ignato?"
