Brandon Sanderson, who is completing Robert Jordan’s epic Wheel of Time series, is giving fans two chances to win a walk-on role in A Memory of Light and raise money for charity at the same time.

From his website:

I realized that we had something very special in the Wheel of Time book–an opportunity that shouldn’t be passed up. I wrote an email to Harriet, telling her about the charity that Pat had been using for his drive. It’s called Heifer International. Instead of just giving food to the poor, they go into developing countries, give them animals to care for, and teach them how to use the livestock to create a sustainable source of income and food. It’s a fantastic idea, and a worthy charity. I asked Harriet if she’d mind me auctioning off a character in A Memory of Light. She was behind that 100%. As some of you may know, Robert Jordan did something like this once, giving a walk-on part to a fan in one of the books. There are a LOT of people who need to be named in this story, and so why not let a few of those names and descriptions go to real people?
