Arone is a small seaport on the southeastern tip of Orbaal. It is held by the Hulthards, an Ivinian clan that conquered the area nearly 60 years ago. Along with the nearby thrans, Arone is isolated from its neighbors to the west by the vast Arone Marshes that form the northern edge of the great Anoth Delta. The keep sits on a low basalt headland overlooking a fine natural harbor that offers refuge to seafarers from the stormy Sea of Ivae and the pirate-infested waters of the delta. The rulers of Arone pay tribute to the Geldestaars at Lorkin, but their relationship is on the cusp of becoming a blood feud.

The Arone Keep article describes the settlement's history, government, religion, economics, and military forces. Includes a full description and color floor plans for the castle, along with color GM and player maps of the settlement. Details are given for many local craftsmen and other locations in the village. Also includes a six-page section on Ormanoam, an ancient ruined temple complex built by the first Hârnic followers of the god Ilvir. Once a popular pilgrimage destination, the site now draws few travelers.
