This is a city with a pyramid on one corner and an active volcano on another, the last of the four blocks holds a building that is melting in the lava of the volcano. There is also a wall that is protecting one block of the buildings and another wall protecting the pyramid. The wall protecting the final block has been destroyed. The purpose of this is to show how being prepared is important. It also shows how not being ready or prepared can cause your own destruction. I kind of like it. The volcano was originally a mountain which was just a blob. It was morphed into a volcano and the last block with the building was improvised because the volcano took an unexpected amount of improvised work.
