Heartless are interesting creatures. Created from the bodies of those who have lost their hearts, they have one purpose: to destroy the gate to Kingdom Hearts, thus overflowing the Four Planes of Existance with Heartless.

A Keyblade is essentially a giant key-like weapon. It can be used in many ways, like to seal the Keyholes of each world or to be used as a weapon. There are many people who wield Keyblades, but only Keyblade Masters, like Sora or the Unknowns from Kingdom Hearts 2, can use the Keyblades to their full potential.
"So, this thing is called a Keyblade..." -Riku
