Neverember's Enigma, while also having several other names, all refer to the great secret, or treasure, of former Open Lord Dagult Neverember, who left it behind after his exile.
Rumours swirl around the true nature of the Enigma, though many sources claim that it is in fact the purported half million gold dragons embezzled during Neverember's reign as Open Lord.
The location is also a mystery, though several groups are on the move, believing it to be somewhere within Waterdeep.
