The Secret Vaults of Kas the Betrayer by A.E. Jackson

Earthquakes have been reported in a region south of the city. A landslide has cleared large swaths of land away from a massive granite wall buried deep under the hillside. This granite wall is merely the edge of a much greater Highwall Peaks mountain range.

Four guards were sent to investigate an ornately carved stone doorway revealed on the face of the granite wall. They were able to pry the stone entry open just enough to slip through. During their preliminary search a map was found in a room off the hallway they explored. The room resembled a gatehouse or officer's quarters the guards stated.

Comparative research by the Great University and a brief review of local lore revealed this as the possible location of 'The Secret Vaults of Kas the Betrayer'. The story is forgotten legend now, merely an insignificant footnote of the Third Age. However, if the stories are true then the Vault must be explored extensively - at once.
