(Xpost from DMAcademy) Brainstorming: What would be your empire's ulterior motive for constructing a big rail system?
Hello! I'm at a bit of a crossroads where the next leg of my player's adventure is probably going to involve this empire-sponsored, region-spanning rail line that I've introduced, and I'd like to just kick the prompt out into the world and see if a creative jam can get the imagination brewing. I feel like I've had my nose so close to it for so long that its a little hard to shake free of past ideas and think outside the box, if you know what I mean.
Basically: this empire - which is more ambitious than it is evil, though the actions of one can certainly bleed into the other without much energy - is building a rail line that will connect its capital to its farthest border. At the moment, hints to the players have been that they're building quickly in order to move troops for a potential invasion of a neighboring city-state.
That's a great real-world-adjacent reason for such a project, but I want to maybe inject a little more fantasy in there, maybe a bit of of a mystery as well.
My first instinct was to have them be building the rail into the shape of a giant glyph, and have a golem-driven doom train that is threatening to steamroll the countryside to make this thing happen. But I may have written myself into a corner there with the rail currently being a straight line from east to west instead of a traditional magic circle lol. Either way, I'm just interested in what surface from an internet brainstorm, and would rather have real, human ideas involved :)
