From back cover:
In the heat of an unnaturally warm summer, the Knights of Takhisis conquer nearly every inch of Ansalon, even the glorious city of Palanthas. Mere days later a messenger arrives in Palanthas bearing a dire missive: Something wiped out the Knights posted at the Tower of the High Clerist and now cuts a swath of destruction across the countryside!
Chaos Spawn pits your heroes against one of Chaos's strongest minions: the Daemonlord. They must race against time to save the city of Maelgoth and its citizens from a terrible fate at the hands of this spawn of Chaos. If it razes Maelgoth, the Lord of Daemons may grow too powerful for anyone to stop - your heroes are Ansalon's last best hope!
Chaos Spawn uses the AD&D® game rules and provides information suitable for running the adventure using SAGA® rules as well. This adventure and its companion, Seeds of Chaos, detail the epic battles of the Chaos War, described in the novel Dragons of Summer Flame by Margaret Weis and Tracy Hickman.
