Strange Bedfellows

From the introduction: Being invited to a clandestine meeting in Crow's End is not unusual for heroes in Ravens Bluff. However, this invitation is from Relaru Dayspring, Ambassador Carrague, and Vondryx, Lord of the Abyss, who once "saved" some adventurers when their adventures led them to a dark and evil place. At that time, Vondryx said the time would come to replay that debt; now seems to be that time.
