The Heart of All Hearts is where the final climactic battle of Kingdom Hearts III takes place. It is a dark place, situated in the middle of the most powerful darkness in the world; it is so dark, that not even Maleficent dares to enter it. Teaming with Heartless, Unversed and Nobodies, it is a dangerous place that only the most experienced of Keyblade Bearers can pass through it safely - and even if they do, they will still have to defeat the Armour of Darkness before they can progress any further. It is here that the final climactic battle between the heroes and villains takes place, and only one group can come out alive. The heroes... or the villains?
