[Marvel comics] What is K'un Lun and who are the people who live there?

I'm only on episode 4 of Defenders so I'm asking about the comics to avoid spoilers. But at least in the MCU, it seems to imply that K'un Lun is just a regular place that is only accessible every 15 years and the people there are just well-trained humans. Are they actually something more than that in the comics?

That's the basic gist of it. K'un-Lun is kind of a separate dimension only partially attached to the real world, only accessible at certain times in certain places. It's one of the Seven Capital Cities of Heaven, each with their own champion like the Iron Fist.

Not everyone in each city is highly trained, though - for the most part it's just a regular city, just unattached to the Earthly plane.
