The Red Citadel

The Red Citadel is the ethnopolis of the Tenuvians, the capital of Tenuvium, as well as the de facto capital of the Foederatio of Centum.
It is a coastal city situated between the Spider Forest to the north and the Dry Oak Forest to the south, both of which serve as natural defensive barriers which would inhibit Satemid armies from attacking by land, but also endanger those who leave the safety of the walls of the city. As a result, there are no settlements besides the Red Citadel with sizeable populations in the heartland of Tenuvium.
The city suffers from many problems, such as decadence, overpopulation, and multiculturalism, but remains an important political center in the western Thinlands as well as a prime trading hub owing to its central location along shipping lanes within the Bay of Bisquick. One can book passage via regular routes to Bembridge and Seltcrag, to Endhaven and Pepetela, even across the sea to Tel-Medivh or the Pandermon Fortress.
It was historically ruled by coalitions of Tenuvian noble families prior to the Consolidation of the Geeves. Today House Geever is the dominant political power in the city and hold the most influence over the Foederatio of Centum.
=== Behind the scenes ===
Acacia was chosen for the roofs in the city because it resembles the clay roof tiles one sees in Dalmatia or Florence, and because of this uniformity, the name "the Red Citadel" was chosen taking some inspiration from the Red Fort in Civilization V. It was entirely coincidental that the seat of government in Game of Thrones is called the Red Keep.
