Subterranean

The 508
[Heavy Encryption] 

 -A permanent encampment of  the Chosen 508 descendants of the 508th Light Infantry Regiment of the Imperial Guard, deep with the Lava Tube networks below Asterion 

 -Has developed into a self-sustaining colony that continues to hold a line against Xenos organisms that appear linked to the Cinquefoil presence on the planet 

 -Locations within the settlement include the Command Lodge, the Enge (which contains a Reactor), the Omry (Resource Storage and Repair), a Mess, and a Chapel. Appears to have three entrances; Westgate, Eastbraid, and the North Junction.  

 -Presence of Xenos organisms indicates that a source may be found near the 508's position; merits further investigation. 

 -A rogue Castellan Robot, previously a component of Vector van Flange's retinue, is likely still roaming the tunnels near the 508; instructions on how to safely neutralize and transport the device have been relayed to the Guard.

 -The location where the  Nemesis Artifact was discovered; see the Lava Tube Xenotechnological Incident . 

 -The tunnel nearest the Reliquary shows signs of artificial creation. 

 -Status since the Incident has not been verified; it is possible that the Cinquefoil within lives.
