The artifact

We were attacked by some droid. I recognised it, from the descriptions of dr. Valate. 

A Takmahl religious enforcer biodroid. The Takmahl made a variety of biodroids, mostly to be used in lieu of slaves for agriculture, but also as enforcers. To scare their flock into obedience, and shoot them if necessary. It is huge. The Blood Raiders must have retrieved it, kept it as an interesting artifact, and found a way to reactivate it. 

They must have regretted that soon after.

I recall an old nightmarish image that sort of looks like the biodroid, except that the droid we saw also has Sabik religious vestments:

We tried to shoot it, to no avail. I think Idesbald managed to shoot an arm or appendage off it, but it just kept coming. We ran and hid in an airduct, too small for the biodroid to enter. It is attempting to dismantle the airduct from the entrance, but we could crawl away. We found shelter in a maintenance chamber for the station's ventilation system.

From afar, we hear the droid chanting or reciting some Takmahl text, I try to record it as it may be valuable historical information. Also, cross-checking with ancient language databases.
