The worldship arrives in your world...

I was once asked which ‘world’ my setting was in and to be honest I use my own. But it got me thinking, how would you use it in another world?

For this thought I’m going to assume the ship is and has been in poor repair for an extended period. This allows you to use my map below as is. I only really use one deck of the whole ship as I assume lower decks are buried and upper decks extend beyond the atmosphere of a world.  Your can simply run with it being the only pressurised deck if you don't crash it. Assume the Visitor kingdoms are intact, but the human occupants would be optional to use.

Maybe I will explore an undamaged map in the future with multiple decks. Though if you did this the whole ship would likely follow the rules for the visitor territories I currently use.

So how does it did the ship arrive in your world?

The world scar

Like in my world the ship crashes onto your world. You will need to consider how the crash didn’t destroy your world, be it local magic or technology on the now crashed ship. This could have happened a long time ago or it could be a recent campaign event. Where did it crash? What did it destroy? It is big enough to wipe out all or part of a whole kingdom. In Kanahu this could be directly off the map in the sea to the west or south west or in the unknown lands to the east.

The district nine problem (but bigger)

The ship arrives and is floating a mile above the terrain. It’s still functional gravity systems maintain it in a static position over your world. Or maybe it drifts following some pattern? What happens to the terrain underneath? The worldship is massive and would block out the sun killing all plant life underneath! If this is a recent arrival and kingdom underneath will be rushing to have it moved assuming their people haven’t already fled. If it has been there a long time a dark land underneath will be dead and decayed, maybe becoming a place filled with long dead cities to plunder.

The new moon (it's really a space station)

A more distant arrival, a new moon arrives in the heavens and strange visitors arrive stealing resources and people for purposes unknown. With the aid of an astronomer the moon is identified as a vessel of some kind, do your players explore it? They could use a teleport spell or kidnap a visitor ship to arrive onboard. Do they encounter humans from a distant world or are the Visitor remnants the only survivors?

Combinations (the Sokovia solution) 

Combining world scar with a new moon above. Is a solution to a world ending event in your campaign one where your players or some other force deliberately seeks to crash the ship into a kingdom or location with the intent to destroy it? How would they do this? what are the implcations? 

Maybe the crash is going to occur in a year, the new moon will fall! Can the players stop it? 

My efforts to revise the map

I have been playing with worldographer recently and have made a few icons to differentiate the workshops terrain. They have started doing small updates and the recent changes have improved the user experience for me, though I think more is needed still. Asside from the new icons below I have also added some fungus areas as a forest proxy in the map to give it a bit more texture. For these fungus forests I focused them away from the more inhabited front of the ship. The new hexes are explained below the map.

My current progress is as follows:

The Worldship 6 mile hex revised map

Plaza: plaza hexes are dominated by giant mile high and wide corridors with natural terrain beneath. They are often illuminated with sun lamps and make natural passageways through the vessel. They are similar to the blank machinery areas but are dominated by the plaza terrain types.

Hab-cylinder: these giant cylinders six miles wide and high provide unique terrains from alien worlds within. The map icons show them as fertile or conducive to human life or as zones that are infertile or hostile to life. These were originally detailed in my first map here with the starting city of Avril being in a prominant cylinder.

Hanger bay: these massive open structures have access hangers to the outside world where visitor fleets once berthed. Many opens underneath the vessel and if it has crashed landed will now be filled with dirt and are mainly inaccessible.
