- "The worst of the dungeons was constructed in the following era by Potentate Versidue-Shaie on the ruins of the Lilmothiit community called Blackrose."

Blackrose Prison, colloquially referred to as simply The Rose, was a prison that was built in the city of Blackrose in the Imperial province of Black Marsh. Akaviri Potentate Versidue-Shaie ordered the construction of The Rose in the Argonian city of Blackrose in the Second Era, and it was built from the nearby Lilmothiit ruins by Pelladil Direnni in a single day by summoning an army of Stone Atronachs to do the labor.
The Rose was the most secure and notorious prison in Tamriel, holding the associates of Jagar Tharn who assisted him during the Imperial Simulacrum in the Third Era.
