The Seven Isles were an archipelago off the coast of Ettinsmoor, in the exterior of the Merepeople Nation of the Eastern Ocean, but under the domain of the Kingdom of Narnia when they were visited by King Caspian X after the Narnian Civil War in NY 2306. The Seven Isles consist of two known islands, with the other five largely undocumented. The islands of Muil and Brenn were visited by the Dawn Treader on its famous voyage. Brenn is the location of the seaport capital Redhaven. In 2356 Caspian heard rumors of Aslan's presance on the Seven Isles and decided to set sail to them at once.
