I'm not much of a follower of comics (perhaps I'm even not using the appropriate term for it), but I have seen the Doctor Strange film and some of Iron Fist - both creations of Marvel.
Now, in both story arcs, there's a hidden city, which looks generally middle-Asia-ish, and is hidden/difficult to access: Three permanent portals for Kamar-Taj, and a once-in-every-several-years portal for K'un-Lun. In both these cities, a monastic order trains people in martial arts and/or some kind of magic or magical knowledge.
How do these two relate? Are they supposedly in the same universe? Just a "aesthetic inconsistency" between the two stories? Something more complicated?
I'm asking about the comics and the movies/TV series (I realize there are different "versions" of the universe for both media).
