Marblecourt is one of the northernmost of the sixteen city districts of Sothis lying between the two districts of Aru-Da and Grand Oasis in lower Sothis. Marblecourt is one of the wealthy, peripheral suburbs of the city and, like other such districts, it 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
