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. The Narrative Drive is protected from the Drift by anchorite plating on the ship's hull, which allows it to establish and maintain the reality bubble from a cold start and gives the ship a degree of passive protection even when the Drive is disabled.
Seamships are typically operated by a bonded pair of seam-walkers; one takes command responsibility while the other directly interfaces with the ship's systems to act as the helm. Combined with a skilled Drift navigator, this allows the ship to move fluidly through the Drift and open seams safely.
