Having analyzed the sensor station Sigma-1, it is important that the Inquisition consider the original purpose of its construction. Tech-marine Tellexus of the Iron Hands chapter of the Adeptus Astartes built this station roughly a century ago and provided it with its initial purpose of data collection, as verified by sealed sections of the station which provided the backup power while the lines were cut. I recommend that you refrain from immolating Adeptus Astartes property without their approval, whether or not foolish locals take up residence.
The inquisition was correct to identify Sigma-1 as a target of interest. There was some evidence of malign augmentation on the surface sections, which has been thoroughly exorcised. As of now, the station has resumed its original functionality, plus a crude yet harmless vox broadcast.
I offer my condolences for the loss of your three Chimerae in the confusion after breaking the station seal. I would have much preferred a peaceful resolution over the loss of such great machine spirits. Perhaps their hesitance to destroy this location was their final act of service to the Omnissiah.
Any further information on this malign influence will, naturally, be sent to the Inquisition.
