Seamship
Seamships are vessels built to travel through the Drift, named for their ability to open and transit seams into and between realities.
While seam-walkers are able to manipulate seams and move between realities on their own, the seamship is the primary means of inter-reality travel for beings without the ability to seam-walk, as well as large cargo loads. The key technology behind these massive vehicles is the Narrative Drive, a form of engine which converts the Drift’s narrative potential into a stable bubble, maintaining the physical and semantic integrity of the vessel and its contents against Drift pressure.
