The falls leading up to this level are usually quite difficult for novices to climb. The sharp spines of layer two jut out of the falls, making mistakes on this climb can easily end in injury or even death. But those who make it to the layer are greeted by a layer full of bustling cities and towns. Third Haven is easily the most populated layer of the Cascades. There are several massive cities on this layer. This layer is run by a royal family, however there is a council of common folk that also give a say on how the layer is run.
One of these cities is Aurelion, a city well known for its college of the arcane arts. It has the largest library in all of the falls. It is a very gorgeous city with much of the architecture that could have only been built with the help of magic.
Blackpool, which is the largest city in the entirety of the falls, also resides on layer three. It was once a trading outpost, but people from every layer began to gather here to sell their wares. Before long the small outpost had grown into a village, then a town, then the massive city it is today. The city still has a massive trading population that comes and goes from every layer. You can find just about anything in Blackpool, from layer one all the way up to layer six.
Outside of the cities of this layer are lush, temperate forests. There are often paths in these forests between each town, most are warned to keep to these paths, as it is easy to lose your way in the foliage. Many Tatsukoi wanting to stay away from the hustle and bustle of the cities can also be found in these forests.
This is what I imagine Aurelion looking like sort of! Just a bit more fantastical.
