Brother Rann takes the opportunity to clean and perform maintenance on his gear. They hadn't been through heavy combat but he'd avail of the rare opportunity as it came along.
Brother Orson speaks before Father Gathrix has a chance to answer
the question asked of him "We have all been asked here because there is something going on here in the underhive. Inquisitorial agents and Imperial Fist scouts as well as entire gangs have been disappearing in the underhive without the usual explanations. Once we have specific evidence to the cause we will dispatch the appropriate Ordos for reinforcements, but until then it is just us. That is us and Sister Catherine, but she had other issues to attend to and could not wait any longer. Should you require her aid you can find her at the Ash Road Abby topside. I will remain here to act as control and judge evidence accordingly. Once I deem you have sufficient evidence we will begin the next phase. Father Gathrix will accompany you three and provide the Emperor's blessings. Questions?" Brother Orson stands with authority ready to answer questions, but you get the sense that he is not very patient.
"I would request you identify the last known locations and times these groups were last in contact. Patterns may help narrow our own search."
"What local conditions changed in the weeks before the first disappearance, if any? Hive quakes, for example, could have opened a route for dangerous mutants to enter more habitable areas of the underhive."
"Good questions Brother Rann and Agent Caericius." He responds and shoots a quick glance at the silent companion in a hooded robe. "The first report came 10 solar cycles ago. The gang knows as the blackhearts went missing with no reports of violence in their sector.The comings and goings of gangers are of little importance so this went largely unnoticed until another gang called the Rathole jokers lost a considerable amount of men and vehicles. This time we had a location, it was near the wildsnake brewery topside near the Ash road. The Rathole jokers give allegiance to House Orlok and there was reports of battle between them and an unknown nomad force believed to have come from the wastes." As Brother Orson speaks he flicks on a monitor that barley comes to life and has low resolution. He points to various points on the map of Hive Primus provided.
"Then the Adeptus Arbites engaged the very same force alleged to have been seen fighting House Orlok previously. They took significant loses and were forced to call in reinforcements to push them back."
Brother Orson turns to Father Gathrix "Do you wish to show them what happened at the stranger's spire Father Gathrix?"
"Yes of course Honorable Astartes." Father Gathrix fumbles with the controls a bit before he is able to change the monitor to show an area of the Hive known as the Stranger's Spire. "As you know Necromunda is one of the rare worlds where xeno presence is tolerated. Some of my misguided colleagues went to spread the word of the God Emperor to these pathetic creatures in hopes of saving their souls. I warned them it would do no good, but their determination was admirable. They never returned, but the Eldar Wardens that police this area gave similar reports of wastelanders being responsible. We can only believe xeno lies so much though of course, so I sent in my own agent. She tracked down an old pipe system that lead deep into the underhive. The presence of an Ambull made her give up the hunt for now. "
"Lastly, Brother Carsten was on a recruiting mission in the Blood Needle Spire hab block 2071. His vox went silent at 0600 hours and his scout bike was never found. After a week long purge of the area we are still unable to account for his whereabouts but in the area he went missing an Ambull corpse was found. According the Ordo Xenos agents it appears to have been mutated or purposefully experimented on. They suggest it is possible the enemy has the ability to control these great beasts or at least direct them somehow." Brother Orson says stoically.
He looks at Agent Caericius"Hive quakes have remained constant. The incident involving the Van Saars experimental weaponry seems to have happened during a large quake, though it is undetermined if it was the cause or effect of the quake."
Multiple augmented ambulls and mysterious forces backing them... a considerable threat. Rann nodded "The organisation behind this has considerable resources and access to technology or warpcraft unknown to us. I have heard of Wyrds and other low grade psykers manipulating vermin but I can only imagine the stubborn Ambulls would be beyond such a simple answer. Exterminating and examining one of them would narrow down the means of their control."
"This is most concerning. Perhaps a heretek group has found a means to control the surly ambull? Regardless, we must find answers and swiftly. I concur with Brother Rann on hunting down a specimen for study."
Brother Orson listens and nods. "Then I suggest you follow up on Father Gathrix's agent in the Stranger's Spire. " He looks to Father Gathrix for follow up.
"Yes, I shall contact her now. She should still be in the Stranger's Spire keeping tabs on potential threats." Father Gathrix flips through the screens on the monitor.
"We shall indeed. Is there anything we ought to know about this agent? Unusual abilities, affiliations, or the like?"
This was a little more along Caericius's line of focus so Rann listened to the questions and information.
The ork in the midst shifts and cocks his head, waiting for the other shoe to drop...
