Dragons of Autumn Twilight

This is an okay book co-written by Margaret Weis and Tracy Hickman. A group of friends reunite and discover that the village they meet in has been taken over by a religious order, called the Seekers who are looking for a Blue Crystal Staff. The group of heroes is attacked by reptilian creatures and later in the woods by the undead. They are given a task to retrieve the Disks of Mishakal, containing the teaching of the True Gods.

The story is based on the Dungeons and Dragons board game. An animated film based on the novel was released directly to video in 2008.
