I thought ven opened the the door of DI
because of the beggining of the game after he does his destati he gets his keyblade and shoots a beam into the sky
I could be 100% wrong though
Riku opened the door to Destiny Islands' heart that one fateful night in KH1 - the Keyblade was disappointed in Riku's bringing darkness to the world, and thus chose the next best replacement (Sora). I know what you're talking about with Ven, but I don't know what he did when he shot that ray into the air. Maybe he was just showing off. CloudStrifeSmile
