I got the idea for the geography of the city by jumping onto google maps and scrolling up along the Mississippi River Delta. Defense was my immediate concern, seeing as how they're so close to the Mourning Marshes, and I figured that turning that kind of lake into a huge natural moat made a lot of sense. My thought was that there was one main gate on the east side, accessible either by boat or through two simple gates in the shorter north and south walls. The major gates against Lake Madriel are used primarily by the people who live in the city, and are only accessible by boat (I imagined a couple of rope ferries) or by swimming if you're willing to get wet.
The northernmost quadrant, Noon's Gate, is named after the gate, which I decided was named after the hospice, which I stole from the Ghelspad book. According to the book, it was a theater that was converted into a temple of Madriel. I named Highsong Park after Madriel's page. Noon's Gate is the artsy fartsy part of the city. On the far side of the lake from Noon's Gate is a temporary settlement made up primarily of low end traders trying to save a little money by staying in a tent instead of paying for an inn. During festivals "Noon Town", as it's sometimes referred to, swells to 4 or 5 times it's normal size.
The eastern quadrant is Morningside, so named because it faces the rising sun. It's the merchant's quarter and is the only real part of Lave that most travellers see. A large open air market fills the entryway of the city along the river and spills into the city proper for a few blocks in every direction. A single watchtower sits on a low hill on the far side of the Hornswythe and a second market has sprung up around it, filled with landbound traders not willing to pay the fares necessary to get their wares to the other side of the river.
To the south is Vigilant's Corner and the Acernoth Gate. This part of Lave is home to the bulk of the cities armed forces. A standing force of 300(?) Acernoth Delta Vigilants reside in the southeast corner of the city, in addition to the city militia and several mercenary groups.
The western edge of Lave is where the city stores are kept, along with the major trading houses and their warehouses. The Sunset and Acernoth Gates are used primarily to get the goods produced by the outlying farms, that are not intended for market, into the city without having to fight their way through Morningside.
Lave is built on a large hill that overlooks the Hornswythe, and at the top of that hill lie The Arbors. The streets of The Arbors are a mass of steep climbs and staircases lined with flowered trellises and pergolas. Government officials and the social elite of Lave call The Arbors home. City offices and sprawling, multi-tiered estates compete for space amidst the slopes.
