The Isthmus of Lustria
The Tomb of Gold is a vast repository of ancient knowledge stored on golden plaques sacred to the Lizardmen. The secrets of the Old Ones may be inscribed on these plaques, which, let's not forget, are carved on solid gold.[1a]
This site is located northwest of the Temple-City of Hexoatl, in the southern slopes of the Grey Guardians.[2a]
