Howdy!
Contrary to what a previous poster said, Fortuna is not a 'trap' and has a fairly quickly growing population. While we are definitely more spread out in terms of players, as we didn't start growing until recently, we have a lot of people willing to help you grow, and with our actual organization being put up after D&SS (allegedly), you'll see a fairly explosive growth of individuals coming in as the game itself also gains popularity.
If you seek an existing, thriving community, your best bet is to look at one of the various other Kingdoms and talk to them and see if anyone would be willing to have a Mayor - plenty no doubt will!
If you seek a community that's just now expanding and gaining traction after waiting to see what the game would be like, and want a more tight knit group of people, you'll probably like Fortuna.
If you'd like, I can give you a more in-depth discussion about the pros and cons of Fortuna vs other Kingdoms over Discord; my tag is Victorious#0001 - Feel free to add me / drop me a message!
