Black Marsh, more commonly known as the Pinnacle of Shittyness, Slave-harvest Fields, and Shameful Scourge of Tamriel, is a province that lies in the south-east of Tamriel. It's full of swamps as disgusting as the inhabitants. Scaly N'wah make this garbage heap of the empire their home.

This is also considered a birthplace of Pyromancy and where Laurentius learned his skills from 'the old withering frog' Salaman.

Black Marsh became the home to refugee sorcerers due to 'rather primitive aspect' of Pyromancy itself which is meshes poorly with with advanced culture, and pyromancers are considered rather unsavoury.'

Pyromancers themselve call this place 'the Great Swamp'.
