We’re going to do some wild speculation here, based on very little actual evidence, because that’s what we do! There was a lot of new material in the new Iron Fist video, but this is one little detail in particular that stuck out. We’ve talked before (and will again) about our paranoia concerning the magical elements of Iron Fist, because there are a lot of them that could easily be scrapped in favor of grounding the story. The cosmological orientation of K’un-Lun is a big one. In the comics it is one of seven (…ish) eternal cities that exist on alternate planes of existence. Once every ten years, K’un-Lun’s dimension overlaps with Earth’s at a spot in the Himalayas, allowing for travel between the two worlds. 

    It would be easy for them to skip this piece of worldbuilding in the show, and just stick K’un-Lun on Earth. But we really hope they don’t, and here we have some evidence that makes us optimistic. We’ve speculated before that the shot of Danny meditating surrounded by shafts of light could show him crossing between dimensions– and the new video includes shots of the Rands’ accident that include the same effect. This white light does show up a few other times in the featurette, so it could just be a cool video editing thing, but it always seems to appear at moments related to either Danny’s powers or K’un-Lun, and that’s enough evidence to get us excited.
