Helstrom is the capital city of Black Marsh and is known for its wonderful yet dangerous alleyways. The impenetrable interior of Helstrom ensures that the city would not be besieged by the Empire. It is one of several possible locations that the Eternal Champion may discover in The Elder Scrolls: Arena.
At the time of the Second Empire in 1E 2811, the Argonians retreated to the city of Helstrom for its impenetrable walls that no man or mer can breach. Eventually, Black Marsh annexed into Cyrodiil and its Empire. Black Marsh eventually joined the Second Empire at the Four Score War at the Battle of Bodrum.
- When Arena was going to be a tournament-based game, Helstrom's team was known as the Pit Daemons.[UL 1]
