Duchy of Muros

The Duchy of Muros, colloquially known as Southern Portigelle, was an Estalian duchy created in the Division of Portigelle at the end of the War of Diamanterra's Sorrow. The Duchy was formed in 2465 IC as a client state of the Kingdom of Astarios, acting as a buffer region between the Magrittan heartland and the Aragonan states of Portigelle and San Luis. Following the catastrophic effects of the Greenskin Incursions in eastern Astarios, King Felipe III absorbed the Duchy of Muros into his larger kingdom in 2470 IC.
