Poroman Archipelago

The Poroman Archipelago is a small of islands off of the coast of northwest Casalia. It consists of 31 islands located roughly 50 km from the Casalian mainland, along with four small islands closer to the mainland. The archipelago was formed as a result of a series of geologic events, namely, the uplift caused by the convergence of the Casalian and Tiridinian tectonic plates some 300 million years ago, and the subsequent divergence of these plates followed by erosion. This created a landscape of primarily low lying mountains and valleys on the western coastline of Casalia, which the Poroman Archipelago is an extension of. The small sea separating the Poroman Archipelago and the Casalian mainland was once lowland valleys, and has gradually become a part of the sea through land subsidence. The Poroman Archipelago, along with the rest of the highlands along the Casalian coast, are gradually declining in elevation as this process of land subsidence and erosion continues to this day.

The Poroman Archipelago has long been inhabited by the Sawucha, the largest ethnic group in the modern day nation of Poroma. The islands were united under a single country multiple times in history, most recently by Tagazhi Tenesa ya Masabea, whose campaigns formed the republic that governs Poroma to this day.
