Grasp of Orcus
Douven Staul is eternally grateful.
The matter was complicated when Bob and Urn fell into the company of Bree, a wizard and former cleric who had known Staul as a child and considered him a role model in her life as an adventurer.
The possible conflict of interest was resolved when it was discovered that Staul had been captured by Kalarel and his cult of Orcus. Bree, Bob and their companions slew his captors and freed Staul, who was so grateful that he gave the book to Honest Bob freely before departing for home.
The party has heard nothing of Douven Staul since he set out to return to his beloved wife.
