Bazaar
From MHWiki
The organizers of the Bazaar used to travel abroad with a merchant companion named Ronza. During their visit to the Burroughs region these quirky folk felt right at home, so much so that they decided to stay! Their newly constructed shops are now known across the Kingdom for their strange inventory.
Merchants: Cheese Shoppe, Cartographer, General Store
