The coastal capital of Zilargo, with its crisscrossing and flooded streets, serves as the center of the gnome shipbuilding trade and a major mercantile hub. The Tower of the Triumvirate rises over the central portion of the city. Traders arrive here regularly from Aerenal, Breland, Stormreach, and even more distant ports. It is said that anything can be found in the Trolanport markets, from Sarlonan tapestries to Karrnathi blades to incense from distant Seren Island.
Trolanport is also home to the great elemental binding guilds. All the dragonmarked houses are represented in the city, and House Lyrandar, House Cannith, and House Kundarak have large enclaves that reflect their close ties to the gnomes.
