D&D setting

I woke up a few days ago and I realized that I had e setting in my head for my D&D game.  The natural setting that is.  I had pencilled out the life cycle of the Dragon in this World, different than your typical Dragon life cycle.  In this World, dragons are seeding the clouds with their offspring.  They hatch in raindrops and snowflakes and they spend their time fighting each other and consuming each other and growing.  Fireflies, Dragonflies, Dragon Birds, Dragon Hawks, then they fork and some take to the land and mature more and others keep to the skies.  The dragon Squirrels, dragon Cats, dragon Wolves, Earth Dragons.  The sky dwellers become Kites of various sizes and then Wyvrens.    All this time they are consuming and broadening their area of control.  Then they become adult dragons at about ten years old.  They continue to age and grow, Young Dragons where they gain sentience and languages, Adults where they gain sorcery, Old, Ancient, Wyrm, Great Wyrm and Elder Wyrm.  All the time they are getting bigger and more powerful.  The last stage they become God Wyrm Dragons and become more like spirits and they fly in the skies seeding the clouds with their offspring.  But when man came to their continent, they battled and their magics clashed and the different life stages changed and became permanent for some.  There are dragon like things everywhere.  Moreover, the dragon life cycle means that there are Dragons everywhere all over the place.  

The natural world has insects, birds, reptiles and mammals, but in each of these niches there are dragons at different life stages, everywhere.  The summer nights are filled with the dull green glow of lightning bugs and the bright orange flames of fireflies.  The larger insects and tiny dragon kin are prey to bats and dragonflies and Dragon Flies; tiny lizards with wings the size of your finger.  Then one day if they live they instead of being eaten by bats, eat the bats.  They eat birds, or lose the wings and live like Squirrels eating small animals and mice, later foxes and real lizards and smaller dragons.  In a sense, insects, birds, reptiles, and mammals are joined with Dragons, to fill every niche in the wilds.  In the vast wilderness of the continent there are every type of animal and variations everywhere.  There are primates and lizards everywhere.

The sun rises in the West and sets in the East, because the north is actually the South.  So the sun rises in the East and sets in the West, but nearest pole is  north, the South pole.  I mean, if this world the Earth was a southern hemisphere dominant, our maps would be upside down from what they are.  On Earth if we look out from a plain, we can see about ten kilometers, on a hil out further, because the world is the size it is and the curve of the world is what it is.  On this world, this bigger world, you can see about 100 km, but that is true only if it were a plain and the haze of the day was nonexistent.  You can see further on a hill.  Like you would be able to see the lights of the city of Jarda on a clear night, sort of.  It is still over 100kms away.
