My idea for this came after reading "The Chess Piece" by Wentworth, whoever you are. I've linked it in my favorites.
This is really just a scene setting sort of thing. Nothing even happens. Probably nothing ever will.

Insert standard harry potter disclaimer here
The mysterious order of white pawns.
"What not again!" said Ron.
"What" said harry.
"There is another one of my pawns missing again! Where do they keep going?!" This was directed at the white chess pieces.
"That's exactly what I'd like to know" Said the white king, staring at his knights. "I put you two in charge of our pawns. Look what you've done!" he shouted.
"Oh right. blame it on us, you act all brave and official now the big ones turn up." The whites knights mocked their king is perfect sync.
"Insulence!!!" called the white king.
"If you ask me, it's all the black sides fault" said the white queen.
"Yes you would say that wouldn't you" called the the black queen nastily from the other side of the board. "You lot have no discipline that's the trouble. You're pawns break ranks in fear of our mighty army!" she laughed manically, while her king looked on adoringly.
"HA! You lot have never beaten us when we are at full strength!" Called the white knights.
The remaining white pawns looked indifferent, and pulled out miniture packs of cards to pass the time.

"Shut up will ya's" said ron. "Well harry lets play another time, I'll get replacements later, or maybe they'll turn up". Ron and Harry left the chess pieces to their bickering.

"Ha even you're big one is abandoning you" Called the black king.

Meanwhile in another part of the castle not so far away a large gathering of white pawns about 60 in total, was in a meeting. A war weary looking pawn standing on a raised platform about the crowd began to speak. "Greetings all. This is a great day for our order. We are happy to finally bring this great hero of all white pawns in from the cold, I'd like you all to welcome George!!" all the pawns errupted, cheering loudly, a few called for a speach and soon they were all shouting.
"SPEACH!!! SPEACH!!! SPEACH!!!".

George stood up on the platform and looking nervous and excited addressed the crowd. "Hello everyone." The crowd went deadly quiet. "I have been slaving under the white king from the land of Ron for a long time, and I'm pleased to announce that the incompetance of the king still assures that our order is a mystery." a few chuckles emerged from around the crowd. "I am very happy that it was at last my turn to join my true fellows in arms. I have heard so much about you all. I understand that many of you have come from other kingdoms, and in some lands we the king on our side. I will be most eager to hear of all your tales. I can also assure you that we still have excellent operatives in place to ensure that future white pawns from the land of Ron are well informed. I am truely excited to finally be able to directly contribute toward our great cause. Thank you, and may our destiny be our own!!" The crowd of pawns errupted with applause and smiles, they couldn't stop cheering for about five minutes. George is a particulary charismatic pawn. And they all seemed eager to take advantage of his inspiration in their time of critical need.

The mysterious order of white pawns was getting ready for something big. The had become an army. Their quest was about to begin.
