I was replaying Kingdom Hearts I today, and in End of the World, right after you leave the Hundred Acre Wood you enter a portal of flames which takes you to a short corridor with one room. Inside, there's Heartless machinery and you examine the machine and it is a message to "those devoid of hearts" and things like that. Where is this corridor (i.e. What world, location) and what is this room? Any help would be nice!
