The Good of All

A two-round Living Greyhawk regional adventure set in Ket for characters of levels 1–15. Persistent nightmares and a mysterious doorway draw the characters into events set in motion centuries ago, as they determine whether an ancient passage is being opened or closed. An Extended Play Option provides additional material and concludes the Natural Evolution series.
