Does it have to be a poem? B/C this is super lame (and unpolished), but its what I thought of. XD If it breaks any rules just disqualify me, I had fun writing it.

There's nothing like the first snow of a winter season, and as the young James Potter stared out his window on that crisp December morning he couldn't help but feel his heart swell with childish glee. Sure, he was nearly 10yrs old and shouldn't be entertaining such nonsense, at least that's what father would say, but on such a perfect morning all James wanted to do was get out into the endless white. And so now, silently, stopping only to grab his coat, glasses, boots, and his gold and red scarf, he scurried out of his house.
Perfection in White!
James ran forward, jumped, twirled like a child and laughed, savoring the silence and the way his voice seemed to echo off the trees. It was still almost dark, that point just minutes before the begins to creep above the horizon and in the swirling flurries and mountains of snow-drift James could almost imagine he was in another world. He reached down and grabbed the edge of a stick peeking out from beneath the snow, waving his sword at imaginary opponents.
"I see you Salazar Slytherin!" he yelled to the emptiness, "You coward! You fiend! Why are you running from me? Don't you want to talk to your old friend Godric Gryffindor?" He spun, jabbed the stick out in front of him. "I can see the fear in your eyes Salazar! You may be gifted with your potions but I was always the better fighter!" He struck what he considered to be an intimidating stance. "Duel me you fiend! Stand up to me like a man, instead of the snake you are! Oh your running away are you? I knew you were afraid!" Suddenly he was running at full speed towards the woods, a familiar haunt of his. "You can't run forever!"
James laughed and made his way through the familiar trees, savoring the sting of the cold at the back of his throat, except he was no longer James at all, but the brave Godric Gryffindor, Knight, Hero and Founder. He ran with an endless exuberance, typical of a child his age, calling out occasionally to the trees. "Quit your hiding! Face me! I will find you Slytherin!"
On and on further and further until finally he stopped twirling the stick-sword in an elaborate gesture, imagining ropes shooting from its tip. "You've hurt too many people Slytherin, we were friends once but no more! You'll rot in Azkaban the rest of your days!"
He paused. That was a silly thread, Azkaban wouldn't have been around in those days would it have? Oh well. It didn't matter. He'd saved the day.
Now James sat down, out of breath. The sun was just beghing to make its way over the horizon, but it was still dark. Darker than he had remembered when he set out. He stood, scanned his surroundings. Everything looked so diffrent under the snow. All his old land marks were covered and he wasn't sure exactly how far he'd gone into the woods.
Finally he picked a direction, but with only a few minutes the surroundings looked unfamilar. He tried another, only to meet the same ending. Another and another, until eventually, what seemed like hours later, he was back in the place he had started. James shivered, sat on a log, and then began to cry.
Don't be a baby James! He thought to himself. Attempting to quiet himself, but failing.
Mummy will be awake soon, they'll find me then. But at the same time he wasn't so sure.
Something rustled in the trees.
"Who is it?" He yelped, jumping now to a standing position and holding the useless stick-wand out in front of him, "Don't come any closer." He croaked, "I'm armed!"
He closed his eyes, preparing for the worst. But it never came.
Instead, a stag, a ghostly white stag stood eying him about twenty feet away. He breathed deeply.
Quit worrying you fool! He stepped forward, waved his arms. "Go away! Shoo!"
But the stag just looked at him, unmoving even as he moved closer. James stared at it, in truth its pelt was too white to be a normal dear. Its hooves and antlers to luminous. He was reminded faintly of the North Star, guiding sailors for hundreds of years.
Then it turned and bolted the opposite direction.
"Wait!" He called, running after the animal. "Stop!" He wasn't sure why he was following the beast, but he knew he was having to keep a full sprint to keep up with its graceful bounds. "Your going too fast!" He cried, but at the same time whenever he thought he was going to lose site of the stag it stopped and seemed to wait for him. Staring with its luminous eyes untill he had caught up before bounding off again. Finally James collapsed in exaustion. This was pointless! He was probably just more lost now.
But looking up he could see his house beyond the trees. He was at the very edge of the forest. The voice of Maisy, the cook, echoed over the snow. "Jamie!" She called, "Jamie come in now, I have your breakfast!"
It seemed he had only been lost a few minutes after all.
He stood, and ran towards the house, "I'm right here Maisy!" He called, but then he stopped short and looked back towards the woods. "Hey, thanks..." He whispered towards where the deer was, but found he was looking at nothing. Not even tracks in the snow. In wonder he scanned the trees again. Had he imagined it all? Did the stag even exist?
"Jamie!"
"Coming Maisy!"
It was only years later that he would learn the true identity of the Stag. The white stag, or doe, depending on the situation, was a spirit, the spirit of the north star, just as he had somehow perceived. Its job was to lead children home, home to their loved ones.
What he never realised however, was the importance of this sighting. For years later his own son would walk deep into the woods, following the same spirit, albeit in a different form, to find the the sword of Gryffindor. His son then, would defeat Salazar Slytherin, or at leas his heir.
Though, perhaps, the white deer could help a certain follower of Slytherin find his own way home.
