So I have no Idea if this has been discussed in the past or not. I couldn't find any information on them. the Black boxes have been in square games for over 20 years now. They are never shown but the boxes are always some mysterious object that can't be opened or explained and it's hinted they are from a forgotten civilization and then the game moves on. The games that I know they appeared In are Dirge of Cerberus, Xenogears and now from the trailer Kingdom Hearts 3. But really what are they?
