Rangers of the North
Annúminas was once the capital city of the Kingdom of Arnor. It was located in the land of Evendim (meaning: “evening twilight”) along the southern shores of Nenuial (also known as Lake Evendim), the origin of the Brandywine River. The city was home to the Kings of Arnor and was founded by High King Elendil himself. It was the first capital of the Realms in Exile, and housed the chief Palantír of the North.
The city survived for nearly a thousand years, but eventually it declined in population, the Kings of Arnor moved the capital to Fornost Erain sometime before the end of the Second Age, and eventually Annúminas was abandoned.
