sci fi setting description

The path was worn. The blue and gold rocks and pebbles worn down with time, weather, and creatures walking on it. A girl with wings was limping along, huge wings drooping. Her wings are black but of an angels. They looked heavy in the rain. She didn't fly even though the wound on her thigh and hip were leaking silvery - blue blood. It looked painful. The minute she stepped into a clearing, her wings began to glow. Another winged girl stepped into the clearing. Her wings were of butterflies. The colouring orange, black and white peaked out from under a red umbrella. The tip of one poked out from the umbrella and a drop of rain hit it, creating a pebble sized hole. The girl yelped out in pain. The rain is toxic, like every other thing natural on this planet. The yellow water carried disease. The blue trees would give you a severe rash and the pink grass would sting if touched. But that's what happens when two planes merge into one. The planet with all the toxic things is Mercury and Earths clone housed the winglings. This planet is Mearcuear
