True, I had the thought about putting that lol in there but thing thought that you could also just ask about it and learn through conversation. But since we are here lets discuss.
Basically the seal and whaling hunting has dried up some time ago, so this settlement had worked on an experiamental sheep farm. That being said, it failed, the conditions are just too harsh. So the residents are leaving for good. Unless some other use for the island can be figured out there will be no humans there.
Now, just like my adventure, looking up the history will just cause you more problems but this is all true. Settlement, sheep, didnt work. So this is why the it is the last ship there for the foreseeable futre. They need to pack up and close up the settlement and head back civilization.
