We have some already named, but not much. Please, let's use numbers to place the names instead of adding the names over the lands since it will become very crammed very fast. Then we put the names in separate columns along the right side, such as we've been doing with the climates.
Also, what's the typical font that is used? We should all use the same.
A group of rings fell into the planet, nonetheless, could we have a few more that still stayed in place being visible from the planet? That could prove quite interesting as cultural feature and it will help catapult longer range navigation much earlier on this world.
I can already imagine what a person in the first civilizations may think. A wall on the sky, a wall on earth, to keep the men from wandering into an endless ocean. A tribute must be paid to the gods to avoid being flooded into becoming part of that ocean every year...
Wouldn't this planet be more focused on maritime trade?
1.- The places which could harbor civilizations seem smaller, therefore surplus are more scarce.
2.- There is no large landmass like Afroeurasia to have so many land trade routes.
3.- The largest landmass is a desert, caravans can only take you so far more so thinking about the time when the age of sail comes around.
We have enormous wetlands, this means a diverse ecosystem of insects... carnivore plants anyone? I don't think it interferes with the forests.
Never underestimate the power of silt along those rivers though.
