November chuffed a little laugh; a motion that rippled through all of her duplicates, not quite in sync. "It is not ours to see beyond the Veil," she said. And such was her purity that you knew it to be true. She would not dare to look upon the Mysteries of the Omnissiah, even invited so. But she appreciated the trust, even if she was worthy of the trust.

"Alright, alright. Here's the specifics of the murder, as best as I understand them," she said, focusing in a bit as she transcribed a sequence onto the dataslate. 

Location: Archmagos' Tower. Single point of entry/egress. Two tech guards on duty.
Attacker approaches directly through the corridor.
Attacker uses a plasma grenade to disable both tech guards. 
Detonation is noticed, skitarii response team scrambled.
Attacker breaks the door and enters the Archmagos' sanctum.
Attacker fires at the Archmagos, triggering her displacer field.
Somehow the bolt penetrates the displacer field and strikes the Archmagos' brain, killing her instantly.
Attacker breaks a stained glass window and exits via grav-chute or other rappelling device into the refinery complex.
Skitarii response team arrives.
Full search of the area conducted. No sign of attacker identified.

[Forensic Pathology] This account does not add up. You have no doubt November has transcribed her theory accurately, but on a basic level something about this [i]feels [/i]wrong. The machines have their own logic and the basic rhythm of plasma-alert-bolter-displacer-gravchute has not played out the way it should. There are machines here that have not been identified; machines breaking in ways that have not been considered. 

"I know I've missed something here, but I can't figure out what," said November. "I haven't let the Magi in; they're all suspects and they could tamper with the site in ways I couldn't comprehend. You two are actually the only people in the complex with alibis or allegiances, which makes you the only people I can trust with this. I'll open the site for investigation, if that's all at use to you."
