This is a part of the Lost Crowns DLC for Dark Souls II. Crown of the Old Iron King is set in a massive tower with a black fog surrounding it. The tower is filled with flames, smoke and sorcery. Players have to retrieve the crown of the Old Iron King to complete the game.

The DLC can be accessed by proceeding to the altar behind the Primal Bonfire. This will take the players to the starting area of the game with the addition of the Heavy Iron Key to the inventory. This grants access to the Brume Tower.
