Kingdom Hearts as a Portal

Remember when the Guardians of Light aimed at Xehanort and shot a beam at him in order to abuse his status as a Portal and create a warp-point that led us into Scala ad Caelum? Well, what if the Master of Masters' plan is to create Portals through every single Worldline in order to freely traverse through them? For all we know, you can only jump from one Worldline, to another, but we haven't been shown whether or not you can return to a previous Worldline you've already jumped from.

But what could be powerful enough in order to use as a Portal to each Worldline?
Yep. You've guessed it: Kingdom Hearts. A "Worldline" is a world, or rather, the universe where worlds and people reside. And what's the collection of those hearts? Kingdom Hearts.

But, what's the point of creating a Portal from Kingdom Hearts?
You wouldn't need to cast your body away, and it can be used as a means to circumvent the rules of time-traveling, and you wouldn't need to do what Luxu did: jump from vessel to vessel for what probably could have been millennia.

I think it's possible that a portal is precisely what kingdom hearts is. In kingdom hearts 1, kingdom hearts was depicted as a literal door between realms. Its possibly Nomura has simply expanded upon this idea over the years and there is evidence to support it.

The first time kingdom hearts was summoned during the first keyblade war was when Ava was able to escape to the unchained realm with the dandelions.

The second time kingdom hearts was summoned by master xehanort in KH3, it opened the way to scala ad caelum which master xehanort describes as "the place from which all worlds spring". Furthermore when master xehanort weilds the X blade after summoning kingdom hearts, he proclaims "there is one sky", perhaps implying that kingdom hearts is something shared not only by each world, but possibly all worldlines as well.

Perhaps wielding the x blade allows one access to control kingdom hearts and thereby traverse the worldlines as they please. Perhaps the reason the master of masters needed the keyblade war to happen is precisely to forge the keyblade so that he could then return and seize it for himself.

Who knows? Lol

What you say makes more sense and logic than my theory. Perhaps there are multiple Worlds, and Kingdom Hearts is the singular force that isn't replicated. Maybe this is why the Foretellers returned: after Master Xehanort opened Kingdom Hearts, perhaps Luxu seized the opportunity to make the Foretellers jump from their War, to present time.
