Kagurani

The Kagurani is a steam locomotive that typically travels between Gravefellow, Lantern, and Acarletto. It typically carries high value goods like radiant steel and steamjacks. It does not travel to Detrino to avoid the ongoing war, so many of its goods are traded out at railyards to other trains that are willing to risk the journey.
It is conducted by the 4-tailed kitsune Conductor Rasu Kolida, a powerful warcaster. Rasu's protoge is a young goblin alchemist named Revu of Devil's Thunder.
