I've had this world for awhile, and have several stories in mind to center around it, but, I haven't developed the world very much. I'd be sooooo grateful if you awesome people could hive me tips and suggestions!

Awai is a world in a separate dimension from a partial sci-fi Earth which will also be in several stories.

Awai has two large continents, each located at one of it's poles, with lots of islands surrounding each. Awai also has two suns, each located at the poles, that give each half light and warmth. The suns double as moons too, because at night, their light and heat dim down to a moon-like quality. However, they still shine brighter than a normal moon, so the stars are barely visible.

Northern Continent
-tropical climate
-Forests
-Swamps
-Marshes
-Mountains with vegetation
-Humanoid races
-Non humanoid races
-unique creatures
-Cities with steampunk technology
-unique plants
-dimenshon crystals (Yes, they are spelled like that!)

Southern Continent-
-Thick mist constantly surrounding it
-colder climate
-cold deserts
-rocky terrain
-Snow-capped mountains
-Dangerous animals
-Uninhabited for the most part (But the bad guys definitely know of it)

As you can see, the southern continent isn't as developed as the northern one. Also, I'll expand on any of the list if asked. Thanks so much!

How exactly does a sun dim down?

To be honest, I haven't figured that out yet....
