The Stone City is the 26th Discovery that Vyse can make.
The ruins of a settlement built into a solid rock wall, with countless passageways connecting the dwellings. The homes appear to have been abandoned hastily, but no evidence has been found that explains exactly what happened.
This can be found on the Northern Coast of Valua, south of the Philosopher's Stone. Conversely, the Philosopher's Stone is found north of here.
