Now, this is how to fast travel in The Elder Scrolls 5: Skyrim.
Like all good subway maps, this is schematic and not to scale. It's full of wonderful little touches, like the ground and sea connections to other parts of Tamriel; putting "Skyrim Central Station" in Whiterun (of course), and even adding a gondola up to High Hrothgar, which I don't imagine the Greybeards are too crazy about, but it should help Klimmek deliver the groceries next time.
I'm also imagining my latest re-roll, a dark elf thief, was picked up trying to jump the turnstiles at Helgen. Then he gets to merspreading on the Riften local while Karliah and Vex scowl at him.
