Once you have completed all puzzles the only thing you can do really is collect all collectibles and make all stews and reach maximum population. Also if you haven't got all your 50 esteemed elders just try and work for them. This will make sure you have something to do!!!

With the totems i only have 3 esteemed elders which 2 totems are exactly the same and the other is different. So by the look of it, it is just random
