The Meirm Sea was a major body of water on Sriluur, known for its high acidic content. The eastern edge of the Meirm Sea was known as the Copper Coast, due to the amount of the pulverized copper in the sand.
Because of its proximity to the sea, in the early morning, Meirm City was often covered with a coppery fog composed of sea spray and chemicals that could harm the skin of sensitive species. This mist left behind a copper-colored dust if not washed away before midday.
