I love Wood elves. I help them when I can. such as slaying a spider or two.
What is wierd is that one moment they are greeting you kindly, the next, filling you full of arrows, and the one after that, asking you to do them a favor.
The answer is a chess board, and a pawn. For those who don't know' when a pawn gets to the last row, they can turn into any piece save the king. This usually come from the taken piece pile.
The pawn always starts on 2 (or 7, for the opposite side) and attempts to get to 8, the last row (or 1, ftos).
