The Interplanar Flight Rail has opened its newest route at last: a magical locomotive carrying passengers to the realm of the fey. But when the train breaks down deep within the Astral Plane, adventurers will need to make their way through the magically malfunctioning cars to face what awaits them in the engine room before the endless silver void outside becomes their final destination.

This whimsical high fantasy adventure with a dark underbelly takes characters from 5th to 7th level aboard a sprawling interplanar train packed with memorable passengers, magical chaos, and fey intrigue. As the train hurtles toward disaster, adventurers must uncover the truth behind the breakdown, survive the Fey Line’s increasingly unpredictable carriages, and save the passengers before the entire locomotive is lost to the Astral Realm.
