After getting a look at a preview of what the Crystarium is like, I personally feel we should get a housing district here. Such a vibrant, and expansive area. This would be the next best place, after Ishgard that is, to get a place in. I can imagine the housing district being a mix between The Mist and The Lavender Beds in style and surrounding atmosphere. https://www.youtube.com/watch?v=WEVKvoCn0FQ
