Cecil Harvey:
He weilds the darkness like no other. He is softspoken and shy, but his blade, Death Bringer, can rend anything in two with a simple flick of his wrist.
To be honest, he is a Heartless much like Ansem, but his amnesia has erased everything but his need for hearts. He joins the Resistance becasue no one knows WHAT he is... he is not an Emblem, so, naturally, he has no Emblem to speak of. He has a free will and sentient thought. He is part of the heart of the true Cecil - Riku's long lost elder brother- split in two between light and darkness.
Cecil has long silver hair, bright green eyes, pale skin, and wears mostly black. He's about 20 years old, give or take about a year.
