Hidden Depths- Kingdom Hearts Fan Fic

A boy, a keyblade, a nobody, a heartless and a decade of sleep.
Xerim is a nobody, lost, and searching for answers, but when he finds the truth it was far from what he had expected.
Hidden from many, known to so little.
As fragments of Xerim's fading mind fade into oblivion, one light shows him a way out.
A heart of pure light.
To this heart he would tell his tale, and tell why so very few know of his excistence.
This is Xerim's story. One that both started and ended in darkness.
Are you ready?
