I just moved to island 2 without knowing, how can I get back to island 1 to clear it?

I did not want move and I did not know that building the boat automatically brings you to the second island

After leaving an island, you are able to go to the next island or any island other than the one you were on that you've been to.

You cannot clear any of them at first until you get something that lets you permanently close the mountain portal though, and you can't get gems on island 1 anyways. You're fine.

Also, if you lose your crown, you also go back to island 1, and you don't lose all of your progress.

OK thank you very much!

NP, I made a miscalculation last night trying to defend workers who I snuck to the far side of a forest to clear some area for a wall, and lost my own crown.

Moral of the story: If your workers aren't smart enough to run to safety after their work is done, find replacements. It's cheaper in the long run.

Edit: I ended up on island 1 with all the walls missing, but the towers still in place, and most of my archers still around.

But you need to leave island 1 as soon as possible, because there's no way to "complete" it on first visit.
Stone mine are on second island, and without it you won't be able even to attack portals.

And to truly complete island you will need to reach island 4 first.

I was trying to help without actual spoilers, but you are correct.
