cities

I think that there should be cities, cities are larger villages with walls and in the middle of the cities, there should a castle or mansion. There would also be abandoned cities that look like they were invaded and destroyed by Illagers they would be inhabited by zombie villagers. There would also be another variant of a city an underground city it would be like a normal city but completely abandoned they would have a lower spawn rate but they would have better loot. There could also be new mobs such as guards or knights.
