Palanthas
After the destruction of Istar, the Jewel of Ansalon quickly became the most important city of Ansalon, although never matching the size nor the power of Ergoth or Istar.
First founded by the Tarsian survivors of a shipwreck around 2,000 PC near a beach after making a pact with pirates, the city of Bright Horizon (as it was first known) developed around the Tower of High Sorcery of Palanthas.
The city itself consists of two different sections: The original Old City, which has the shape of a wheel where the palace is situated at the center and where the Tower of High Sorcery was originally. New City, which consists of small houses constructed after the edification of the Old City.
