After the acolytes returned to Hive Sibellus, they found out that their safe house, as well as a few nearby buildings, had been destroyed in an explosion. In search of answers, they headed to the local arbitrator headquarters and started to scour through the vast archives for the name of Calistria. After finding a few leads, and after securing a permission to check the bombing site themselves, they started to make their way back to their leveled safe house. However, while travelling through middlehive, they were attacked by a sniper. The sudden shot and death of an unfortune bystander caused mass panic on the crowded streets and the acolytes barely managed to get to safety in the chaos. Not content to just flee, they gave chase to the assassin and followed the trail to a local dwellcomplex. Soon they were able to find the source of the shots in a local dwelling, but unfortunately the sniper was long gone, having left behind a murdered family.
The acolytes resumed their investigations and returned to the bomb site. After reaching their destination, they were once again attacked by an unseen sniper. With two of the group heavily wounded, the acolytes and the arbitrators at the bomb site managed to drive away the attacker. Unfortunately the sniper had left behind him traps, and one of the arbitrators was killed by a mine. Still, evidence suggests that the acolytes, or the arbitrators, had managed to wound the attacker.
While searching through the ruins of their old safe house, the acolytes received a message from their master, inquisitor Irquol Sul. The message was delivered via astropath, and it ordered to them to evacuate Scintilla immediately.
Flight was arranged for the group, and soon they were on an orbital shuttle heading towards Emperors Black Mercy, a Black Ship of the Inquisition. The acolytes spent the next few weeks aboard the unnerving vessel, and finally arrived to their destination, the planet of Landunder.
