Swamp rot

Swamp rot was a disease that could be contracted in the swamps and marshes of Tamriel. It drained the willpower, strength, and agility of both mer and men before ultimately killing them. It was predominantly contracted in the swamps of Black Marsh and in High Rock around the city of Daggerfall.

Swamp rot killed many acolytes of Mara who were based at the Temple of Mara in the town of Umpholo in Black Marsh within one month of their arrival.
