Calamar stood as the capital city for the world of Esseles. Due to the planet's agreeable weather and deep past, Calamar became a hub for refined culture; its outskirts were filled with extensive parks, art institutions, holo-production firms, and advanced educational facilities like the Darpa Center of History at Calamar. The seat of government, known as the Hall of Esseles, could be found inside the city.
A significant cell belonging to the Rebel Alliance had established its base in the entertainment sector.
