Cities

((This has to be refined))

To make defending settlements easier, humans, giants and the few survivors of the other races have formed large, very dense megacities, which now hold the vast majority of the population, the biggest of the being Aevum, the eternal city. While these cities of course make for bigger and juicier targets when it comes to demon or dragon attacks, they can be defended much more efficiently, whether with Magitek turrets, special units or even directly by the gods, as is the case with Aevum. These megacities can be the size of citystates, and usually consist of the normal city at ground layer, with multiple, walled in rings (the protection getting stronger towards the center), and at the very least one underground layer. In the case of aevum, there are also living areas carved into the mountain it is built around. The living conditions in these cities can vary significantly, with some areas incredibly packed and slum-like, and others opulent and luxurious.
