Looking at the map in the dim light, they can see that they're in the sewers of the Castle Ward now, which is located on the western-central side of Waterdeep. Directly north of the Castle Ward is the Sea Ward, the northwest corner of the city. To the northeast of the Castle Ward, and the east of the Sea Ward is the North Ward. Living in these three are the upper-class of Waterdhavian society, and the buildings there primarily serve as government buildings, temples, high-end shops and festhalls, and for the North Ward especially, noble villas.<br/><br/>Directly east of the Castle Ward is the Trades Ward, where average-quality shops, taverns, and festhalls are located. South of the Castle Ward is the Dock Ward, where low-end shops, taverns, festhalls, and the occasional brothel, strip club, and drug den are located. Southeast of the Castle Ward, at the southern tip of Waterdeep, is the South Ward, another source of average-quality shops, taverns, and festhalls, since it is the first place that travelers from south of Waterdeep enter.<br/><br/>(And nestled in between the North Ward and the Trades Ward, on the eastern central side of Waterdeep, is the City of the Dead, Waterdeep's cemetery filled with moss-covered mausoleums and the tombs of wealthy nobles.)<br/><br/>{And here's why I just described the map of Waterdeep in some detail:}<br/><br/>As the adventurers begin to head east through the sewers from the secondary pipe that they're currently at into a wider primary pipe, twenty feet across with the same five-foot walkways on either side and a flowing stream of sewage in between, they notice that the Castle Ward sewers are relatively clean, or cleaner than expected. Perhaps this is due to the nature of the Ward above, and the fact that it's likely that the sewers here are not used as much as they are in other wards, neither for foot traffic or for the transportation of waste water.<br/><br/>Occasional signs on the wall give directions concerning which ward of the city they are currently below, and which surface shafts (as they're numbered on the map) lie in either direction, along with distances to each of them. The Cellarers' and Plumbers' Guild certainly seems to have made some effort to make navigating the sewers as easy as possible, whether for themselves or for anyone down here illegally.<br/><br/>The adventurers head through the sewers in the only direction available to take them deeper into the sewers for easily twenty minutes, the large pipe taking them south, then southeast, then south again. Heading south down a large primary sewer pipe, twenty feet across, the adventurers notice that the sign on the side of the sewer reads "Surface Shaft 46 ahead / Now entering Docks Ward". The water in the middle is higher, and is now just barely below the grimy walkways on either side.<br/><br/>{At this point, I need marching order for the two groups, the group on the west side of the south-bound tunnel, and the group on the east side.}
