Polis shows how hard the Vigilants are trying their best to change things. The current generation doesn't remember what the Ayyon looked like before the Nightmare Fuel - but they believe in the Dogma and are building Polis into what you see now.

No doubt - there is still a lot of work to be done. The air is still musty and smoke-soaked in most neighborhoods. Not all of the planet's scars can be repaired with current levels of technology. And trees, unfortunately, only grow in the Domes. But it's a big step for now.

We can discuss the humanity of their methods as much as we want, but looking at the lights in the center of Polis from one of the Domes, we can imagine that this is what the future of the planet could look like without the later.
