Oldstone is one of the sixteen city districts of Sothis, and is located in the south-east of the city in 'upper' Sothis. It lies between the districts of Newstone and Scorpion Road. Like the other rich, peripheral suburbs, Oldstone contains large oasis circles; wide, tree-lined streets; and excellent facilities for its inhabitants. These residents include wealthy merchants and craftsmen, civil servants and even nobles dwelling in their mansions.12
