Bazaar

Bazaar is located on lowest level of Highwatch. It has exits to the upper levels of Highwatch and one exit leading out to the Highwatch Outskirts. Also merchants, banker, trade broker, Artisans Hall for crafting needs, Vanguard Quartermaster and crystal merchant and Fishing Association NPCs.

You can actually fish in pond here, but it doesn't give fish, just paper trash and also a achievement.
