OK, from the clues in the screenshots, what can we work out so far? It looks like the villagers have built a raft (they were either the group that left in the VV2 event or another group). From the storm in the second picture I'd say they get shipwrecked on the north shore of Isola. Since the game in the first pic has only just been started, they must have found the castle, or fort, or whatever it is, and started to clean it up so they can live in it. All seven villagers (adults) are in view in the screenshot so they don't have any kids right at the start. From the bamboo used to patch holes in the "fort's" walls, and lying on the ground, the builders use that as a material. If they need the shelter of a "fort", does that mean there are dangerous animals or possibly enemy tribes about?

Any more deductions?
