George R.r. Martin said this quote
“ The pale pink light of dawn sparkled on branch and leaf and stone. Every blade of grass was carved from emerald, every drip of water turned to diamond. Flowers and mushrooms alike wore coats of glass. Even the mud puddles had a bright brown sheen. Through the shimmering greenery, the black tents of his brothers were encased in a fine glaze of ice. So there is magic beyond the Wall after all. ”
