This magnificent stone art by Jon Foreman

I saw these stone-circles on reddit and thought about this game. I don't know how something like that could be implemented, but it looked like it could fit in the game. I just posted this here in case it sparks any ideas - now or in the future...

Maybe some kind of a nest for the dragon egg? A teleport pad? Or just simply a waypoint marker?

Those are pretty neat. The first one reminds me of ancient wells that are a spiral ramp lined with stone that I plan to add to the game.
