The svirfneblin accepts your money without comment, passing each of you a parchment ticket with indecipherable text covering the front and back.
Once each of you has bought a ticket, he addresses Achkby's and Aeroz's questions. "You'll be wanting to take the train all the way to the Glimmersea. It's the end of the line, so you don't need to worry about missing your stop ..."
The rumbling gets increasingly louder and you see the other passengers lining up by the edge of the platform in anticipation.
Six massive bulettes sweep into the station, screaming, in a cloud of steam before skidding to a stop. The bulettes are harnessed 2 x 3 to a series of long passenger coaches. The bulettes' chests heave with exertion and steam rises from their slick, armored backs. Occasionally one will open its enormous jaws and screech loudly. It is not immediately obvious who or what is controlling the bulettes.
The Underdark denizens begin climbing into the carriages.
