Arthur Marks is the Royal Mayor of Windmore and was appointed by Lord Jakov ir'Hornsheath.
Lord Mayor Arthur Marks governs Frosthold, a major trading community on the Iceflow River in northern Karrnath. The port town facilitates the exchange of agricultural produce, timber from the Icewood, and minerals from the Icetop Mountains. Lyrandar and Lhazaar ships come upriver to buy these raw materials and sell manufactured goods from the rest of Khorvaire.
This region of Karrnath was in many ways abandoned with the outbreak of the Last War, as the ringing bells of levies pulled every able-bodied adventuring spirit away. This led to a resurgence in the native monsters and spirits of the area, keen on reclaiming what was theirs. Since the Treaty of Thronehold, Arthur Marks has prioritized reclaiming the lost communities and mines that have sat empty for decades, hiring mercenaries and adventurers to clear a path.
