Rider's Creed

Set seven years before book one, this is a story about Vaska, an Assassin-in-training, and his dragon Epsilon as he is trained as both an Assassin and a rider. Unfortunately, being the first Assassin and rider in a hundred years is going to be a bit troublesome because he doesn't want to be either one of them, but his partner will try to show him the importance of his position.
