Kern is an island citym built on an island of Mermidon River.

During the Third War of the Races, Menion Leah warned the city that Brona's armies were coming. Many managed to save their lives as the city was sacked before Tyrsis. It was significant to the kingdom of Leah since Shirl Ravenlock, the wife of Menion Leah was from there. Shella Leah visited the city with her mother once.

Since the war, the city was rebuilt although burned sections were stil seen. Jak Ohmsford with Shella and Brendel visited the city on their way to Arborlon to rest and resupply.
