I think that the Peacekeepers would definitely oppose Humans First, the Wild, and the Alliance. They would also try to keep law-abiding organizations from attacking each other and keep interdistrict strife to a minimum. They would, for example, engage in acts to keep the Necropolis and the Temple District out of each other's business.

As for the council of ministers, I like it.

I think that the Trash Corps would employ certain monsters in the disposal of trash. Rust Monsters would handle metal scraps, while Otyugh would be able to handle all manner of organic trash and sewage. The Otyughs' own waste would then be used as fertilizer. What other monsters do you think would be put to work disposing of trash?
