Everything you see aside from the little bit of exploration near the merchant and beyond, is all one "connected" island. There's even more not yet revealed.

I'm defining "connected" here to mean any section separated by a body of water that is shallow enough to be built on or swap across using foods available in Meadows/Black Forest only. So there's a little island hopping here and there, but a ship or raft isn't required to cross between the islands.

There's some really cool places to build as well. We're currently holed up in an "underground" base built under rocks in a mountain area in the North.
