This is a classic snowy room with a waterfall and a cave behind the waterfall. However, I've removed the trees and the grass and... added more furniture nodes! The original mesh of this room only has nodes within the cave :( Sad day. So I added them as far outside the cave as I could. Your character can now get out into the pond. Not quite to the stones but into the waterfall and into the pond near it as well as on the banks.
