Minecraft wiki entry for Building_a_metropolis, associated text: Flame City Make a town and set it on fire. Netherrack and magma blocks are good for this purpose. Use lava in places where water would normally be found. For example, fill any wells, rivers and ponds in your city with lava. Striders are one possibility for transportation, but make sure they won't be exposed to rain, as it damages them. Make the population blazes and magma cubes. Possibly, you could also allow players with Fire Protection armor or ample potions of Fire Resistance to visit from time to time. You can also use mycelium instead of grass and gray concrete powder instead of sand because they look like ash (you can also use basalt as burnt logs). You can also outlaw water, and if you need to execute somebody, do it by burning them alive. Make sure not to build with any flammable blocks, for obvious reasons.
