Firstly there was Dark.
Only The Impenetrable Dark and nothing else. She was ancient and nobody knows when she was born. But something happened and The First Spark. In such way The Dark get a friend. 
The First Spark is very sly person, so she made so much sparkles as there are stars in the sky. Stars were born that way. 
Stars become bigger and bigger, some of they cracked and from their explosions The Galaxy Dust was born. She is the wind, air, she changes everything and give something new or bring everything... Sometimes she is "wicked", but because of her lots of galaxys were born. 
The strength of Galaxy Dust (she loves to run through The First Spark's stars) gusts was so majestic that dust's grains were heat up by stars and The Suctive Magma was born. She is the first fire and stone, disturbing force and creative power at the same time.
But not every star was hot, some stars were so cold that if the hell was true they could freeze million hells! The grains of The Galaxy Dust which were flying through cold stars became beuutiful crystals. So wonderful, but so weak over fire stars. Crystal dust were dying near warm stars and The Aquatic Deep (The Great Deep) was born. She isn't evil cos of great storms, she also can save in her calm dark underworld. And when The Aquatic Deep first met The Suctive Magma the first life was born! The Backwoods. 
As the Impenetrable Dark can't live without The First Spark, The Backwoods can't live without The Suctive Magma's strength ant The Auatic Deep's calmness. Firstly she was very fragile like the first flower under snow, but became stronger and stronger. As the first light was born in the deepest darkness, "mice and men" was born in the darkness of The Backwoods.
