There is no Antarctica world
you dont you attack your mama
the world that never was, past the brink of despair.
You kill them, you might have to level up a little though.
If my memory is correct I believe you go back to Jaq.
The moment you die you start a new game
You have to ride on a dolphin/use dolphin kick to get past the currents
Find the key hole! Past the cliff area in the caves with the waterfall
*NO SPOILERS*Yes. Many people mistake Kingdom Hearts Birth By Sleep for Kingdom Hearts III. Kingdom Hearts Birth By Sleep is a prequel to the first Kingdom Hearts explaining Sora's past and focusing on three new protagonists: Terra Aqua and Ven. This is commonly referred to as Kingdom Hearts 3, because of the secret video trailer at the end of Kingdom Hearts II. Kingdom Hearts III is not officially started yet, but Tetsuya Nomura has stated in interviews that Kingdom Hearts III will focus on Sora once again, saying that "...Sora will remain the hero until the end." He also said that many more games will come after Kingdom Hearts III, so fear not.
Its tells of the past of previous Keyblade wielders. There is a short scene of a brawl better then "Keyblade Masters" that results in Kingdom Hearts being produced and Mickey showing up to potentially clean things up.
