Margo Island was an island just south of the Corisandian mainland.
It was separated from Corisande in the north by West Margo Sound and from the smaller island of Tear in the east by the Margo Strait. (map)
The island, which was ruled by the Dukes of Margo, was part of the League of Corisande until the latter was dissolved and its territories incorporated into the Charisian Empire. (BHD)
