Some throws indeed. I'd definitely like the nuclear winter idea that Violet put forward. Also, I'm declaring a vote so that we can continue with artwork instead of fumbling with concepts.

1. Normal ruined octagonic city
2. Ruined octagonic city with plants
3. Ruined octagonic city with very few plants
4. Ruined octagonic city covered in snow/ice
5. Ruined octagonic city taken over by sand
6. Ruined octagonic city in space

Please vote for one, we can decide the alternate version(s) later.
