A source who wants to remain anonymous allowed me to post these images of the gate to Tabbetzur located in Offikatlin. It is likely that the cloud is related to the gate being deactivated. The gate is in the cloud.
I also noticed a Deathless research outpost in the system, it seems to have been destroyed thanks to the efforts of Drifter drones and capsuleers. I had planned to send warclones to raid the other infrastructures present the site but it would have been too dangerous since some capsuleers are hostile. I assume that even if I send them after the capsuleers have left, the Circle’s agents on the scene will have already evacuated and possibly taken compromising equipment and information with them.
