Minecraft wiki entry for Building_a_metropolis, associated text: Mutant vs. Normals: The city can revolve around the X-men. Randomly-picked citizens can be taken to strange locations or laboratories where they are given powers, like Unbreaking and Curse of Binding-enchanted elytra, which will not break easily and will not be able to be removed. The other players can try to hunt down or imprison the 'mutants', which will lead to a lot of prison breaks. Mix up the powers and locations to give it a random, more natural feel.
