At first, people ruled the land and they alone ruled. Cities were constructed everywhere, wars were fought and treaties were signed. But one day, as if the Earth intended to return all of what humanity built back to nature, monsters and beasts of all types out of nowhere overran each city in waves of overwhelming numbers and left each one in ruin. Only one city was strong enough to defend from the relentless attack thanks to a combination of magic, technology, and 50 meter high walls. They were all that was left of humanity... Them and possible survivors on the outsides of the wall. It's been several years since then and life within' the walls have been manageable. But with the rise of overpopulation, lack of food and water, and looming beasts that threaten what little they have left of society, risks will need to be taken. Perhaps with some help from a particular from a substance that turns monsters to Mamono, they could take back what was once was humanities. Of course being only a recently discovered resource many tests will have to be conducted first...

The Last City is a steampunk/fantasy setting.
You can be human, monster, or mamono. If human you're options of introduction are already been born and have lived in the city or have arrived at the city looking for sanctuary. If you choose monster it's the same as the human's options. Mamono's options are you're either looking for sanctuary or have been experimenting with DE, been monitored after turning, and been allowed to become a citizen of the city.
Most monsters will be controlled by me but if you'd like to add your own you may if you ask me ahead of time and get the OK. Also if any of you like to control a monster that just been turned into a mamono that was originally controlled by me, go ahead.
For why monsters are allowed to live in the city. Monsters that have gained a sense of humanity have proven themselves to the city and have been allowed to live inside. Plus this will cause some interesting conflict inside the city since monsters are the reason why humanity is in danger.
The city name is Zelous.
And finally, no overpowered characters.
