The shrine is in itself nothing more than a weathered pillar in the greater Goldvale area of “The Not So Dense Forest” to a forgotten god standing in the location of a country estate1) now known as Club Haversack.
Development
The estate is presently home to some dwarven bandits who have tangled with but made peace with the party2). What was figured out however is that anyone / “any body” left at the foot of the shine is resurrected!3) This seems to be one of the reasons the bandits love their property.
When the players first tangled with the bandits, the bandits succeeded at keeping something hidden from the party by having it submerged in the well.
Later via gossip from Ginger some party members learned that the bandits were coming to toss the Haversack “artifact” into the Warlock Well. So that was what was hidden previously. The outcome of tossing it into the well is unknown.
