The Diadem Gravtrain is an extremely fast train that is able to circumnavigate the planet of Palisade.[1]
History[edit | edit source]
The Gravtrain originated as the railway of the Diadem, the ancient trench city on Palisade's equator.
While the city itself is now nothing but ruins, Stel Kesh was able to use an operation centre in Carmathen to reactivate the Gravtrain. It is now a pillar of the Bilateral Intelligence Service.[1]
