IV - There are still many mysteries surrounding the Castle of Oblivion. Was the castle itself constructed by the Organization and was Naminé originally a subject of the experiments going on there? Please tell us about the details of the Organization’s experiments. Also, was the pod Sora entered somehow related to the experiments done by the Organization? Was the pod in Twilight Town the same sort of thing?
In the end, the Organization’s goal is to obtain the Kingdom Hearts of people’s hearts and to fully exist. These Nobodies are called “those who don’t exist”. (Riku: In other words, the Third Enemy referred to as the Non-Existent Ones in Deep Dive.) In order to assume a new existence, information about their own personal circumstances must first be gathered. A Nobody’s main characteristic is that without a heart they use memories to form the parts of a personality and emotions. For them, memories have become an essential element. The birth of Castle Oblivion itself is still a mystery but before the Organization was born into this world it was there. The Organization discovered this castle. You should be able to make some guesses from the additional scenes this time, and be fairly quick to be able to think of the next stage.
