The train itself was actually roomier than you had expected. There was little in the way of common spaces, and sharing one car as a single room was not the worst thing in the world. After almost a full day's travel it was starting to wear a little thin. Phina had poked her head out of the lab car at the end every once in awhile, talking excitedly with Nix about what it would be like out there, living the life of adventure. But much of her time was spent in her lab car doing whatever she was doing in there. She only made a few references to working on 'something big'.
The other two crew cars ahead of yours were filled with the soldiers. Their cars were a little more packed. Bunk beds helped to house them all, but space was still limited. The middle space between them was usually filled with a few barrels that were used to play various games on.
The view outside was as unchanging as it had been since this morning. Once you left the station you entered a dark tunnel. You've been in a dark tunnel. All you see outside is the walls of a dark tunnel, only somewhat lit by the lamps inside the car. It's been hard to judge how much time has even passed, but Phina, on her last visit had mentioned it had almost been about a days travel, but at this rate it was starting to seem like it had been at least two.
The train continues to chug on through the dark tunnel, completely unaware of the passage of time, but still chugging dutifully. You're feeling tired and ready to bunk for the night/day/whatever time it may actually be outside of these dark endless tunnels.
It is around this time you feel a bond start to forge with the Rod of Absorption. You suddenly get a sense of the past of the weapon, and it's current level of charge. It currently has 8 charges left in it. In it's lifetime it has absorbed more than a thousand spells. Whoever had this before made good use of it.
