At the edge of the world you come across what looks like a ship harbor hanging off the map. There are powerful purple foglights illuminating the area. The construction has seen its share of action but looks well-maintained overall. Dockings and cranes extend over the abyss. Several mechanics, traders and passengers mill about waiting for some form of presumably airborne transport to arrive.
For a while you attempt to get one of the dockworkers to speak to you but most seem too busy to respond. Others ignore you outright. Odd.
