Drefenberg is the largest city in Suletstraya, the largely rural, agricultural region of Blerpusdorf. While not a big city by any means, it's certainly important, as it is the seat of the local government and the main port for anything coming in and out of the region. It's nestled on an island at the mouth of Suletstraya's life-giving river, the Rien, meaning it controls most river traffic. Of course, this can only mean trouble when the port city becomes a flashpoint for the civil war to wreak its havoc again. However, this time, there's no siege or battle. Why? The Suletstrayans don't have a single division stationed there - their sole defensive force is out in Streffen, negotiating with the refugees there. So instead, the civilians of Drefenberg put up the fight. All the bridges were torn down, defenses were constructed, and boats were scuttled to dam the river - crippling the Rien. While most of this was useless, with the city falling in just a few days' time, the regional commander of the Ketzian forces, one Derek Meffel, decided that other government loyalists needed to an example. So he razed Drefenberg. All of it. Over the course of a week, the city's populace was forcibly evacuated to the banks of the Rien, before the main island was blown to smithereens by missiles and artillery. Anything that wasn't destroyed was engulfed by flames. Along with it went much of the region's legal documents, historical artifacts, and practically the entire regional economy, with total collapse predicted in a month's time due to the limitations of the only other deep water port available, tiny little Kostavej. Meffel made away with spoils such as priceless art by Suletstrayan artisans, the Governor of Suletstraya Jim Polak, former Big Seven CEO and high profile prisoner Cristopher Dawel, and much of the city's money. The government in Cubertshaven has denounced Meffel, and by extension, Ketz. Ketz is yet to comment.
Kind of rushed, but whatever, it gets the point across. Map of the overall civil war here: https://scratch.mit.edu/projects/1304330381/
