The door to Light and more(spoilers)

Ok, so according to kh1 Ansem (Xehanort's heartless) The door that was sealed at the end of kh1 was the door to darkness. well, as we all should know, Kingdom hearts is the heart of all worlds and with every heart comes light and dark, with the exception of the princesses of heart. (there could possibly end up being another exception to this rule, perhaps there are Princes of heart. if so, perhaps they are the opposite of the princesses of heart.)

Before sealing away the door to darkness, mickey says to Sora, "Remember, there will always be a door to the light." when they close the door, Mickey uses his Inverted kingdom key to lock the door on the inside, while Sora uses his keyblade to lock the door on the outside.

So far we know for sure that there are three ways to open a pathway into Kingdom hearts.

1. through the door to darkness (no longer available because it has been sealed)
- note: this is the way a heartless would attempt to enter kingdom hearts.

2. the yellow moon that forms when gathering a collective amount of hearts released after killing heartless. (currently not available due to the real ansem's machine)
- note: This was the way the nobodies attempted to enter kingdom hearts.
- 2nd note: The reason the hearts gathered to form a moon, was because they could not return to their original body and soul. After being killed a heartless release their hearts which, in normal circumstances, then returns
to the proper body and soul. however if the that body and soul became a nobody, then the heart goes into suspended animation giving you the yellow moon we saw in kh2.

3. And the blue moon that forms for an unknown reason during the birth by sleep trailer. (will probably end up not being available after birth by sleep)
- note: It's a safe bet to say that the Unbirths seek Kingdom hearts for their own reason and this will most likely be their way of entering kh. Also take note that this moon is blue which is also the Unbirth's color.

I have stated many times before that I believe that heartless represent darkness, nobodies represent dusk, and unbirths represent dawn. If this were to be the case, then we are still missing an enemy that represents light.

alright, going back on topic here (I have a habit of rambling). At the very end of the epilogue for kh1, some words pop up saying, "Remember Sora, you are the one who will open the door to light." Interesting, huh?

If you have completed kh2, then you know that Sora has already opened the door to light. so now we have the door to light open. could that mean we have our fourth way into kh available? if so, then it would be reasonable to assume that this will be the way that the next enemy, if there will be one after the unbirths, will try to enter kingdom hearts. Perhaps this means that Mickey and sora will need to seal this door up too.

Going back to entry point number two, the yellow moon. When Ansem the wise ruined this entry point with his machines he said anything could happen. when the machine blew up, millions of hearts rained down on to The World That Never Was. here is what I want to know, what became of those hearts?

I suggested before, on another forum site, that part of the "anything could happen" that Ansem mentioned could be that a new enemy gets created from these hearts. This theory of mine, however, was quickly shot down by someone, on the site that I wrote this on, who was supposed to be like a kingdom hearts know-it-all. He stated that that scene "clearly showed the hearts turning into heartless when they hit the ground." I argued that the heartless could have merely been attracted to the mass amount of hearts, but he denied that and continued to shoot me down, as well as a whole bunch of other people. I finally gave up and dropped the subject.

Well recently I took another look at this scene and found, to my delight, that this is not the case. When the first heart hits the ground, instead of one heartless being formed, three of them appear! So unless the game designers made a mistake, it would seem that this "know-it-all" didn't quite know it all. this brings us back to the possibility that some other form of creature may have been created at that very moment. Could this be the case?
