Retrieve the Key That Opens Any Lock

Type: Main Quest
Region/Scope: Onadbyrr → Tomb of the Constructor

Overview

A master key exists—capable of opening any lock, mundane or magical. It is vital for bypassing the sealed Royal Quarters during the party’s future infiltration of the palace.
The key was once held by Deverellio Prankar, a brilliant thief and terrible gambler, who took it with him into the Tomb of the Constructor, a resting place tied to a minor deity.
He never returned.
