Curse of the Crimson Crown
the Transversal Engine
When it became clear that travel back west was not going to be an option, various engineers, technicians, and magicians began to work on a method of travel back and forth to and from the homeland en masse (for those who could pay the exorbitant travel fees). The Transversal Engine was their crowning achievement.
Working on several unconventional principles, the train operates normally within the confines of the station – however, when outside that it occupies space in the astral plane (and does most of its travel there). This bypasses nearly all of the Silt Sea’s denizens, and allows the Engine to move at phenomenal speed. The issue of track originally promised to be a significant challenge, but through dark magics, bound devils, and various arcanistry, they laid a track in the astral plane over the entire Silt Sea.
