This world has a great many biomes and cities, meant to evoke the same grand scale of other fantasy worlds.

I have only worked out a few specific locations, one of which is Spireshire. It is a landscape of rolling hills and overgrown vegetation on top of ruined skyscrapers, some miles tall and wide. This is where Liv calls home when we first meet her.

I don’t have a specific name for this location right now, but it just came to me one day. This would probably be an abandoned city ripe for scavengers and filled with pre-war robotic guardians or bionic beasts who still believe they are soldiers in an ongoing war.

Just because it's the post-apocalypse, doesn’t mean the world has to be dead. There are still thriving large cities scattered around the world, including one containing other worlds within it! But outside of that, this concept sketch to the bottom right is for a city called Nucleus, located around a large reactor deep within the planet. The planet is actually almost hollow, a series of caverns with their own biomes and inhabitants. Creatures who call underground home often pass through the city. The planet’s core is actually alive, but few make the journey to it. Nucleus has several boroughs, categorized as “rings.”
