Stone of Golorr

The Stone is one of the keys to opening the vault which holds the money stolen by Dagult Neverember. Although the Strings of Fate promised to give the stone to Jarlaxle Baenre, they instead left it in the care of Durnan.

The stone is fleshy, with three eyes, and is inhabited by an Aboleth. The party stole the stone and one eye from Manshoon, bargained with Jarlaxle for the second, and received the third from Xanathar in exchange for getting him a new fish.

It is important to note that the Stone is not the actual key - it simply stores knowledge. Aboleths are creatures that existed in the very beginning of Aphra, before the planes were split apart and when gods were still walking Aphra. It potentially stores a lot of very important and powerful information as a result.

At one point, the Stone talked to the party, giving them a warning not to enter the vault.

As of Episode 19, Jarlaxle has tracked the party to Wheldon to retrieve the Stone. It has gone missing from Durnan's care, and there is a hole in Durnan's memory. The party insists that they do not have the Stone, but Jarlaxle has definitively traced it to Wheldon. In exchange for Jarlaxle calling off his threat to the genasi family, the Strings of Fate agree to help him locate the Stone.
