I have delivered the supplies to the geologists on Gammel XI, they were very happy with this gift.
After that, I went with a shuttle and scanning equipment to explore the region. I tried to find traces of any Sani Sabik colony or signatures of wreckage of their cryoship - they would have disassembled it to construct their colony but parts of it may have remained, and that would be scannable.
Alas - if there ever was a Sani Sabik colony here, there is no trace of it left. I found no signatures of ruins of a colony, and no sign of the remains of a cryoship. Either they settled elsewhere, or they were completely destroyed by the cataclysm that occurred here.
It seems I am at a dead end here, and with not much to do I will return to Mehatoor, where the Sansha logs that I received from Stephanos Varkonis are still waiting to be investigated.
