Okay so after the ending KH1 after Mickey and Riku closed the DTD and got trapped do we know how they got to Castle Oblivion. Do we know the events that got held in the realm of darkness and hot they got out? havent played Re:COM and i wanted to ask this

Riku somehow made his way to the castle with the help of DiZ and Mickey eventually got out during Riku's time at Castle Oblivion.  How Mickey got out is a bit iffy, something about the light, but I do clearly remember that Riku could smell the darkness.  Apparently he could smell something that no one else could...

Oh yeahh ahahahahah the smell of darkness ;p

We know that somehow DiZ helped Riku get out of the RoD but we don't actually know how Mickey managed to do it!!! He just showed up in CO in front of Riku!

Probably Riku opened a "door" like the Nobodies.

Later Mickey said to he " remember you can't open doors now"

Ansem Reports in KH2.

 

Secret Ansem's Report 11 I was reunited with an old friend at Castle Oblivion, but was unable to disclose my identity. If he knew the situation, he would likely try to stop me from carrying out my revenge. As much as I would dearly love to converse with him as in the old days...that is now but a hopeless dream. My friend has been fighting in the realm of darkness. Most likely he found his way there through Traverse Town. Like Castle Oblivion, that village also rests in the cleft between light and dark. It consists of the remnants of worlds whose hearts have been stolen by the Heartless. It is where those who have barely escaped the destruction of their worlds eventually find themselves. This "realm between" is quite unstable, with corridors of darkness appearing from time to time. Whenever a world disappears, some of its inhabitants must arrive here through these corridors. Surely Sora traveled these same corridors of darkness when he first came to Traverse Town. It seems my friend, fighting in the realm of darkness, appeared in Castle Oblivion through a corridor of darkness constructed by Organization XIII. My new ally Riku also effected his return via one of these corridors. He swore to me he would give his all for his best friend Sora. In fact, Sora's memories have been slow to return. Thus I have asked Riku to bring me another Sora—his Nobody. Sora is indispensable if I am to achieve my goal. I require the Keyblade-wielding hero to fly through the realm of light and defeat Organization XIII.

The ansem reports...they hold all the answers

Very true. Without ansem reports, it would be a little more confusing and difficult to understand the series.

They're probably going to be flashbacks in KH3 about him in there, and who knows he could have bumped into aqua

I should probably read them then... I never really bothered with them before despite knowing their importance lol

I doubt there are flashbacks of that. No point in even putting that in there. Also no way he bumped into aqua...

Yeah I it was DIZ who brought Riku to Castle Oblivion.
