The Cielos Dam is a large dam located on the upper portion of the Argent River, and is located adjacent to downtown Cielos in Silvermoon. Its creation caused the formation of the Argent-Cielos Reservoir. The Cielos Dam was created with wealth accumulated from the lindori trade under Iami Aeruma, who established Cielograd laborers' camp nearby the city to ensure a timely completion. Although it was slightly damaged in the Cielos Riots during the Silver City Civil Conflict, the dam remained functional, and is still a functional and vital part of the Aerumaen economy. The dam slows the rivers' flow enough to allow Silver City and Cielos to become viable inland ports, and the reservoir is used as a basis for public tap across the nation.
