While the Venomous Demesne and Shaarat Kol aren’t part of the Western Frontier, the smugglers encountered on the frontier often traffic in goods from the Venomous Demesne and have dealings with sailors in Shaarat Kol. Lost isn’t on any map of the Western Frontier, but you never know when you might stumble across this mysterious town. Beyond that, on the Western Frontier, you may encounter or play a medusa from Cazhaak Draal, a kobold from Shaarat Kol, a changeling from Lost, or a tiefling from the Venomous Demesne. While these cities aren’t actually part of the frontier, they play a role even from a distance.
