Ilighôn was one of two islands that made up the Eyes of Silvanus on the Sea of Fallen Stars. It was situated close to the mouth of the Vilhon Reach. It benefited from the protection of reefs and also the magic of the Emerald Enclave. The Eyes of Silvanus were formed from mountains when Jhaamdath fell.[1]

With the retreat of the waters of the Sea of Fallen Stars, due to the Spellplague, the island became part of mainland Turmish.[2]
