The river of names
The longest river in the Ninth World of Grista runs through the Continent and doesn't belong to any of the countries. If anything, some consider it its own country, but everyone is allowed to travel in its waters and exploit its resources.
Every two days a ferry starts the trip from the Wrinkled Valley to the coast, while another begins to travel in the opposite route. They stop in the stations in all of the villages and towns along the river. Most travelers prefer to use this transport.
The villages
They seem perfectly ordinary settlements. Some more welcoming than others, but all friendly in their own way. The ferry stations aren't often part of the villages, and it's totally possible to travel trough the river or visit it for entertainment, research, business or any other reasons, without ever meeting anyone in the villages. Those who decide to visit a village, or use the resources or the ferry stations that are inside of a town, may leave without ever knowing about the peculiarity they all have in common. Is not a secret, but people don't usually notice that everybody in each village shares a name. The village name. While other communities are connected by beliefs, history, race or similar qualities, each of the settlements near the river is build around a name. Because the inhabitants come from different places and cultures, some may show different spells or variations, while others give the word a different meaning.Geography
The widest river in the Ninth planet, this twisting waterway exists in the same proportions in every plane, which is considered an anomaly.
In the ninth world, it lies in the middle of the main continent. It is one of the few rivers there, and gets water from many underground currents, not all of them known, and it becomes wider and wider on it's path.
It's particularly deep in the Wrinkled Valley. Only a few hills and mountains are close to the river, including the Isle of Lone fishers which is a plateau around which the river runs in two branches, and the legendary Bridge which the river passes through.
Ecosystem
The river is surrounded by forests that vary according to the soil, height, magic and weather among other circumstances.
In several regions, especially in some of the villages, the impact of neighboring human settlements is evident, while others are totally free of human activities.
Natural Resources
While it doesn't carry any special metal, there are plenty of plants and animals that can't be find in any other place of the Ninth World (or in the universe), but the permanent exploitation of those resources is usually in the hands of the villagers settled near the river.
Some wizard tribes visit the river looking for magic, and the artists come for inspiration, but more than anything, it's an important source of water and energy for the whole continent.
A river that's the same in every plane? And it sabotages offensive magic?? That sounds frickin' awesome and scary at the same time!
Too low they build who build beneath the stars - Edward Young
I'm glad to read that. It should have a nice contrast with the peaceful, uneventful life in the village I'm planning to describe.
