I've been think more about the name, and I am going to nominate Erraxy.
It's still a nod to the founder of the modern RPG, of course. The citizens of Erraxy are known as Erraxans, who produce Erraxian goods in an Erraxite style.
Since no one else is doing anything on this project right now, and it's been clearly stated that it's first come, first serve; I'm going to name the city Erraxy. (In all fairness I did post on this topic a few days ago and if someone absolutely hates it, we can always compromise.)
