I think there's one entire portal artifact for every color of the rainbow which means there's 5 portal artifact pieces for all but one city (that city is the final one you can get). however, there could be another 5 portal artifact pieces from the final city so you could preview, not edit, but preview your friends' cities and see how they're doing.
