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.
Travel along the River Styx to locations and shards further downriver.
Keep in mind that the available paths change depending on where you are.
Discovering and interacting with other areas in the river is certain to lead to unexpected outcomes.
Exploration is encouraged.
