Marketplace is a village in southern Aundair. It's a small settlement, but it lies on the intersection of several Orien trade roads and has a Lightning Rail station. One could think of Marketplace as a large service station, providing refreshments for travellers coming into Aundair from Breland or Thrane.
In particular, Marketplace is known for the Traveller's Toothbrush, a sweet gummy that magically cleans your teeth as you chew it, and allows you to blow soap bubbles.
