Of White Water (rewritten)

Hakoda, chief of the Southern Water Tribe, has three children. He adores each of them, even though they confuse him at times. Katara, his youngest, was born early on a cool morning - he remembers that the waters seemed oddly vibrant that day. She grew in to a strong-willed young woman with a talent for waterbending, despite never having a teacher.Sokka, the second-born, was born at noon in a cold day that seemed far too normal. Clouds dotted the sky like they'd been meticulously placed and the waves crashed into the ice precisely every five seconds. Sokka grew to be a clever boy. Though he couldn't bend, he had a mind that challenged those of the boys twice his age.Finally Hakoda's oldest - the one that confused him the most. He was born at midnight under a full moon so large, it looked like it would have touched the ground. Kya almost died that day, but she prayed to Tui and La. The waves grew fierce and silver light streamed into the hut. Then, a snow-pale boy with moonbeam hair and eyes like bloody gems was born. He didn't cry, not once, and grew just as quietly. He was light on his feet, waterbending came as natural as breathing, and he was fiercely protective of his siblings. They named him Tobirama.
