Grand Cedar Isle was created on September 6th, 2023 by crlowman as a way to insert sovreignty of the islands as “Caradra County”, because a significant portion of the Dulmia World Congress opposed to the incorporation of the county. He made several houses in a rather unique color scheme, a cactus tower, paths, and a mansion across the strait.

Grand Cedar Isle is located on both the westernmost and the central islands of Caradra County. The downtown area is located on the central island, whilst the Mayor's House is located on the westernmost island.
