Approximately 15 days after the Aurora Glorificus leaves the previous subsector, Rogue Traders will receive an encrypted message via astropathic communication:

"Warning: Evidence found of widespread reanimation of the dead within this subsector. (Xeno or Here)Technological, not Warp sorcery. Possibly infectious - present, dormant, in some native inhabitants of subsector, only catalysed upon, or after death (or other unknown trigger).

Recommendation: Cremate (or at least behead) any crew who die. May not stop them being infectious, but probably stops them attacking you.

Will bring sample in stasis chamber for your tech priests to examine next gathering - one time only, examination to occur in discrete labstation, labstation to be incinerated following examination.

Addendum: Apparently an explorator fleet turned (was always?) Heretek, but you should probably ask the crew who came into contact with them for more details.
Much love, Vulgrim"

A transmission is sent from Alabaster Hammer.

Explorators of the Mechanicus. You will likely or have come into contact with reanimated dead humanoids. The Alabaster Hammer have encountered forms at least similar to that encountered by the Aurora Glorificus and the Morituri te Salutamus.

• Reanimation is highly likely result of xenotech implants, hereafter called infection.
• Infection currently identified to take many thousands of years to control deceased.
• Infection not yet identified on non-deceased.
• Infection has not been identified as able to spread from those infected.
• Infection currently identified as result of implantation many years prior to death.
• Source of implantation is currently unknown.
• Infected are quick, strong and resilient.
• Infected should be overpowered and destroyed.

Caution is always required, watch those of the flesh. The Machine God will guide and protect.

Further information will be provided at a later date.
