Drowned Cities

Before the creation of the Titan's Pond, the southwest of Calernia was a great plain. In the plain were the eight cities of Antigone the Titan. These cities were founded as separate cities bound to one another by trade and purpose. When Antigone was lost in the Titans Folly, these cities banded together to share in each others wealth. The eight cities were Alava, Levant, Malaga, Tartessos, Vaccei, Tarifa, Adoni, and Navsari. Each city had a purpose, and together, the cities of Antigone were strong.
Tarifa was given the duty of serving as the political and administrative center of the eight cities. While each city was its own political entity, Tarifa was undoubtedly the leader of the coalition, albeit without a strong central authority. Tarifa helped to regulate trade and settle disputes within the coalition while maintaining relations with the Titanomachy and Thassalocracy of Ashur beyond the coalitions borders.
Adoni was given the duty of agriculture and to tend to all things growing. Adonish magics led to the untamable nature of the Brocelian Forest, and their crops kept city states fed in lean times. The unique, often magical, plants cultured in Adoni were sold through the ports of Malaga and brought wealth into the region.
Navsari was given the duty of knowledge, and was a great center of learning in the region. Large libraries and a central university brought sorcerers and scholars from across the continent to study and learn, while the cities ties to the Titanomachy provided them with great artifacts to study and attempt to reproduce.
The loss of Tarifa, Adoni, and Navsari when the creation of the Titan's Pond drowned them was keenly felt. Almost immediately, the remaining cities began to compete to be the new administrative capital. The loss of Adoni led to hunger throughout the remaining cities, and they began to raid one another for food and goods. Though some knowledge was saved from the fall of Navsari, the cultural loss was more impactful. Without a unified leader or culture, the 5 remaining cities of Antigone have become effectively independent.
