Ladies and gentlemen, may I present Zonudil, "Helmlanterns", a generated city of 262 citizens composed of 4 races, Vulps (fox people), Equids (centaurs), Humans and Goblins. I wanted to share this for anyone else who also wants to try a multi-race city:
https://drive.google.com/open?id=0B5_Jm8L6GFwcMjR2NkQ3VjBuMk0&authuser=0 The story so far: When I started playing, Zonudil was capital and only city of the Vulpen civ The Portals of Coal. I embarked far to the south to establish the fortresses of Abirrakust and then Vutokushat. I quickly realized that the capital could not send any migrants and the initial waves were too few to reproduce. Then suddenly, our expedition leader was made king, and we received word that Zonudil had been conquered by the Human civ, The Kingdoms of Scaling. We thought the city was destroyed and sent a small group of 7 to reclaim the site of Zonudil. Surprised were we to discover that over 200 citizens were still alive and Hostile to our settlers. The settlers abandoned their initial attempt and decided to regroup with better supplies, but when I came back, it was set to Unretire instead of Reclaim and all the citizens of Zonudil were peaceful to the The Portals of Coal again.
If you haven't figured it out, this is a modded game. Vulps are pretty close to dwarves, with trancing, cave adaptation and alcohol dependency. But Vulps are more lenient with slavery, which is probably how all these other people got here and why the humans are at war.
I have not officially reclaimed Zonudil in the save file so that you can choose whether to explore it in Fortress mode or Adventure mode or check the Legends first. If you do choose to reclaim in Fortress Mode, note that you will face several challenges. Zonudil has 262 mouths to feed, but no farms or crops except for what the initial reclaim team brought, scavenged and seized from a hapless caravan. The only water is a frozen brook, and since Zonudil is in the tundra, I have no idea when or if it ever thaws. If you can sort that out, I'm pretty sure The Portals of Coal are still at war with The Kingdoms of Scaling, and since you've already got 262 citizens, you're probably going to be faced with an ambush or siege very quickly, and the randomly generated Zonudil is not very defense oriented. The Portal of Coal does not have any domesticated pack animals, so you will not receive any caravans from your own civ, but that's probably irrelevant since you're essentially extinct.
The good news is that 262 is a lot of manpower to get things done. The Zonudilese have already discovered and walled off some caverns and discovered magma. Zonudil is mostly vertical, so it doesn't take up very much of the map. You could just ignore the generated structure and build your own on the other side of the map, if you wanted to. But your better bet is probably to build some defensive structures into the default depot box structure, which even has a ceiling already.
I poked around a little bit, but I haven't really tried to play Zonudil yet. I noticed that you cannot assign labors to the non-Vulp citizens, but several of them are already Masons or Carpenters or whatever and at least have those labors enabled, and they all have hauling enabled. You cannot assign non-Vulps to military squads, but you can assign them to Noble positions, including squad commander positions. However, Humans and Equids(centaurs) will not fit into Vulpen-made armor, so perhaps military service is not best for them anyways. You could try playing with LNP's Automatic Job Assignments turned on and see if that allows the non-Vulp peasants to perform labors.
Enjoy.
