Correct you are about halfway to the village currently. Due to the hard march. If it was clearer to see you would have been closer. Or if you had darkvision. Also gotcha gotcha just rocks? Or anything else like branches dirt etc?
Nope the one with the umbrella by the tree is just that. Its just leaned up on a tree. Its almost as big as a parasol though. So big umbrella lol. As for the giant its seems to be mining a resource and thats keep the other monsters away.
