He had no real concept of time in this place. His memories were disjointed. Jumbled. He remembered fighting for days on end, running and fighting, running more still, before collapsing. Unable to lift a finger as living writhing beings of darkness descended upon him. He felt them trying to take from him. Take what, he didn't know. But they just took and took. He refused to just let them. So he hung on. Clinging tightly to memories of warmth. Memories of anger. Memories of sorrow and rage. He wouldn't let them take who he was.
Then he woke up in this dark place. A place cut off from reality it seemed. With ichor black shadows writhing and moving. He instinctively knew this place was the Dark Realm. After awareness came the realization that he was changed. Looking at what he had become caused rage and anger to consume him. He couldn't go back like this! He felt empty, like a part of himself was gone that he never knew he'd had in the first place! He didn't know how long he'd raged about, carving a path of destruction. It was only until he realized his emotions were being influenced by his new state of being did he calm down with a herculean effort. The question remained however. What did he do now?
Through experimentation he had discovered he could create portals. He found himself quietly watching Tifa from the shadows, wishing he had the strength to speak with her. But he could not. How could he show himself as he was? His objective became clear. He had to find a way to reclaim what was missing. So he returned to the Dark Place to start his search. Somewhere inside him, he felt a pull. It was his only lead.
How long had he been here wandering the Dark Place? Days? Weeks? Months? He did not know. The creatures that dwelled here, these Darklings gave him a wide berth. He studied them. They always watched him but they did not harass him. Perhaps they recognized him as kin? Or was it some primal part of them that told them he was an Apex Predator? He did not know. But then one day something changed. It was as if the entire realm seemed to come alive. He could feel the pull. The hunger. The pull to devour the light. Someone else was in this place. Clamping tightly down on his new instincts, he quietly followed through the air on wings of shadow.
He found a woman with blue hair surrounded by darklings.

He ignored the growing urge. Instead he dove down from above like a comet, slamming into the ground with wings curled. With a grunt he snapped his wings out like a fan, sending the encroaching darklings flying back. A particularly gutsy darkling lunged for the girl once more, and his left arm lashes out, clawed hand clenching around the creature's neck. With a grunt he clenched his fist and the creature was no more. Yellow eyes panned to the darklings that were hesitating now. He let loose an animalistic savage growl from his throat, an inhuman sound like a roar from a demonic beast.
"Back. Off!" He snapped with fangs bared. The darklings retreated to whatever corners of the Dark Place they came from. Turning, he regarded the woman before him with yellow eyes gleaming. Even now he felt the urge. Sensed the heart within. He ignored it.
"You don't belong here." He said simply.
