Petras is the capital city of Rethwellan. It is located near the center of the country.
Carter's Lane in the city is wide enough for two lanes of wagon traffic in each direction, and wagons move through steadily. It is also the home to several popular taverns and drink shops in a city "well known for its wines and its wenches." (Oathbreakers) Among the businesses located on Carter's Lane is the Pig and Potion Tavern, where Kethry and Jadrek stayed during the Rethwellan coup.
Other Petras businesses include the Fountain of Beer Inn and the White Sheaf Inn.
