Arclands

You're a wizard who got banished from their home because they rivaled the ruling wizard in power. What you gonna do, that's wizard rule right there. Banished citizens are sent to the Arclands - a treacherous collection of islands inhabited by monsters which are attracted to everything magic. That's bad for you and your followers, so the only way to survive is to grow and fortify your village. You will see it grow from a loose collection of rugged tents to a heavily fortified city, attract other banished refugees and discover the secrets of the Arclands.
