Since the Second Empire, Black Marsh was known as the Prison province, as many Empire sanctioned prisons were built throughout the land, among them was the White Rose Prison in Shadowfen, and the Blackrose Prison in Murkmire. The Blackrose Prison was commissioned by Versidue Shaie, the Akaviri Potentate that reigned after Reman Cyrodiil III. Shaie had used his Battlemage, Pelladil Direnni to construct the Prison from the ruins of the Lilmothiit settlement. Within the span of a single day, the Blackrose Prison was completed, utilizing summoned Stone Atronachs. The Blackrose Prison has since been used by the Empire, and other groups beyond their time.
