Next to Charax, other important cities were Forat (at the Tigris), Apologos and Teredon. On his coins Meredates (ruled 131 to 150/151) calls himself "king of the Omani". The latter are mentioned sporadically by ancient writers. According to Pliny (VI.145) they lived between Petra and Charax. They were according to some schola for a certain period part of the Charakene. So it seems that the kingdom extended to the South of the Persian Gulf. However, the reading and interpretation of the legends on the king's coins is problematic.
