Book of Sa'bara

The world is divided by five dragon flights, each headed by a powerful and ancient dragon. People are born, live, and die to the land that each dragon rules. Then, a small band of adventurers, venture into a foreign dragon's land to rescue an arcane elven wizard from slavery. Rescuing her was the easy part. Getting her spell book, the main source of her arcane knowledge, takes going through monsters, hostile and paranoid beings, and the undead, but that is only half the problem. Their unlikely guide, an ill-tempered, ice-inflicted kobold is their best chance to get through without the dragons discovering them. But everyone knows, kobolds are the dragons most loyal servants. Or are they?
