A/N: Hello readers and fans! I've been thinking about writing a Riddick story as well as in addition to continuing my Twilight story. Anyway, here's a preview/ first chapter of what it could be like and what I had in mind for him. Read it and comment on whether you'd be interested or not. Don't own Riddick, Necros, or Chronicles and Pitch Black. All I own is Subject 12274 that I created!

It had been six months since Riddick held Kyra in his arms as she slowly passed. He had become the new Lord Marshal and told that whoever wished a new life must just simply leave Necropolis and would not be counted as a traitor. Several left, but, those who only knew the life of a Necro stayed. Not being the leader type, Riddick spent most of his days wandering the vessel, accompanied by the Hellhound from Cremetoria, and using the training facility to sharpen his skills.

As he was on his way back to his Marshal bedroom, his ears caught the conversation that Lord Vaako was having with a scientist, just around the corner. Coming around it just slightly, he fixed his sight on the two.

"What have the recent findings been Scor?" Vaako's voice rumbled as he looked on a holographic chart.

"Not a damn thing. It's killed everyone we've sent in. I'm almost out of staff in the science department. It uses the same m.o.: They go in, it taps them into a hallucination, and they kill themselves. Then it... well, you know." The doctor took off his glasses and cleaned them with a rag.

"Does it react to sedatives?"

"Its metabolism is four times the normal rate of a human. It burns off the sedation before it even sets in. It heals fast too. Gunshot wounds heal within a half hour."

Damn, this thing sounds like a fun play time. Riddick thought as he approached them.

"And what exactly," His booming voice made Scor jump. "Is 'it'?"

"Ah, Subject 12274, milord." Before Scor could say anything else, Vaako collapsed the chart and handed it to him.

"Keep me updated if anything comes up." Scor bowed and took off. Turning his attention to Riddick, he bowed slightly. "Is there something I can help you with Lord Marshal?"

"Yeah, what's Subject whatever?"

"This thing is nothing we've ever seen before. It turned our Quasi-Dead into what they look like now with a simple bite."

"So what is it?"

"We're not sure, and we can't get close enough to find out either. The elemental that was with you, Aereon, told us one thing when we told her of it."

"And that was?"

"'Fear not the Dark, but, that creature within.' We didn't take it seriously at first. Now, after 35 men have been killed by this creature, we are more cautious." Vaako turned and walked a short distance before turning his head slightly. "Talk to Aereon. She'll fill in more that we can." He turned back and continued walking away. Riddick felt a gentle tailwind blow as he breathed in the scent of the elemental.

"If I take you to her," Riddick turned to Aereon, who now stood half faded with the wind.

"It's a 'her'?"

"Yes, Riddick, it's a 'her'. She doesn't like to be called an 'it'."

"You were saying?" Riddick pushed.

"If I take you to her, promise me one thing." Riddick smirked.

"What's that sister?"

Aereon reached up, put her two hands on either side of Riddick's temple, and stared at him firmly. "That your Furian eyes prove useful in the Dark."

"Lady, if you haven't noticed, I can see in pitch black."

"What you'll be entering isn't just lights out. It's a realm she puts you into. I call it 'Dark'. It's a shadow realm that she was born of, and, it's a shadow realm she uses. She can torture your mind, make you see things, do things that you normally wouldn't do."

"I heard them. They said the Necros killed themselves. Can she do that?"

"It's as easy as breathing for her." She hovered towards the Lord Marshal's throne, pressed a dial on the twisted statue, and the metal chair began to sink down. A stair railing took its place. "Let's go meet her."

After they passed through the scientific observatory, and continued their way down to the domain, Scor had pleaded with Riddick that he wouldn't enter. Riddick just passed on and removed his goggles. Scor had given Aereon a lantern to see as she walked behind Riddick. As the crept down the steps, the nature of the corridor suddenly became thick and musty. It's the blood from the Necros she's fed on. Her scent is mixed in.

"I first learned about her when the last Lord Marshal was going to send her to kill you if all else failed. She was found by the first ever Lord Marshal of the Necros. They had discovered her almost 150 years ago when they took over a Merc ship. They found her frozen inside a transportation tube. She has the branding of the Elder Blood of her kind." Aereon stopped and caused Riddick to look back at her. "Be careful of her Riddick. She's a Dark Elemental. One of the few left. She may look like it, but, she isn't human."

A stinging hit his mind as a female voice chimed from nowhere. What you want is something that's passed. Her spirit lingers though her fate is cast. Riddick looked at Aereon. "What did you say?"

"I didn't speak. That is her. She can enter our mind so easily and pull any string she wants to. What did she tell you?"

"'What you want is something that's passed. Her spirit lingers though her fate is cast.' What the fuck does that mean?"

"Well it's obvious. You want Kyra back don't you?"

"Yes," He felt the sting again, this time was worse. Blood, war, friends and foe. Do not reap what you can't sow. Riddick was getting furious. "Seriously? Why does she keep doing that?"

"She does it to anger you."

"It's working." He growled. A demonic growl answered back into his mind and he got a glimpse of silver-colored eyes. They were her eyes. Shadow, flame, light and ground. Do not hunt what doesn't make sound.

"She's toying with you. She wants you to be sloppy. That way, your brute strength isn't an issue for her." Aereon set the lamp down. "I can go no further. She has raised a barrier of pure darkness and, being a lighter element, I cannot enter. I would…diminish."

"I don't feel anything."

"Maybe because of your human side you can't. Let the Furian in you go. You entered the barrier as soon as her voice entered your mind. The Furian in you may give you the chance of survival."

Riddick walked forward into the darkness. He found two, heavy metal woven doors. They allowed a small space between them. They looked like the kind that'd be used to keep in a large aggressive animal. Scor's voice came on over a speaker. "I will open the doors Lord Marshal. But, as soon as it closes behind you, do not expect it to open again. It is a dangerous creature we Necros wished we had never found." A buzzer went off as the first door opened. He went inside the chamber and it automatically closed behind. "Good luck Milord." Scor said weary as the second door's heavy lock mechanism lifted and turned. Soon, the second door opened and Riddick walked through. When it closed behind him, the massive bolts boomed into place.

Well, I'm alone on this one. He continued walking and noticed that he could barely see in this Dark. His vision was slightly better than a normal person now. He didn't like this sudden disadvantage.

Only death for a companion will you find. The Reaper's manners are anything but kind.

"Are you gonna show yourself? Or play these stupid riddles in my head?"

Fun times for you in store. Into your flesh my claws hath tore.

Riddick felt a sharp pain on his right forearm. He looked down and saw four thick lines of blood running down. This is starting to piss me the fuck off. Riddick thought as he shook out his arm.

"Is it now? I'd call you a Furian, because of your blood. But, you act more human to me." He could hear the smile in her voice. He looked around and saw…nothing. There was no female body to carry the voice from. Her voice is beautiful. Like a siren's. He felt a tap at the base of his skull. He turned to see who nothing was there, but again, nothing. Then, an all too familiar voice came from behind.

"Riddick, did you miss me?" He turned back around to face the impossible.

"Kyra?" Shock was written all over his face. "This isn't real. I held you as you died."

"This is the Shadow Realm. The Necros call it Underverse. The dead reside here."

"You're not real. Where is she?" He looked around for the creature responsible.

"It is real," Kyra walked up to him and held his face in her hands. "Believe this," She whispered as she kissed him. As he began to kiss her back, something felt off. She was cold. And when he went to touch her, he couldn't feel her. As if nothing was there.

Let the Furian in you go. Aereon's voice floated into his mind. Only the beast inside can destroy the illusion.

He opened his eyes and saw Kyra but something caught his attention to the right. He turned and jumped at the shadow, but it faded as soon as he got close. Riddick felt a sudden primal anger to defend and hunt. And he gladly accepted. His vision enhanced. He could see everything around him now. The foggy darkness was gone. He noticed Kyra's apparition was gone too. Suddenly, a pool of darkness formed in front of him. A figure rose from the pool and took form. The shadow faded away and there stood a female. Her hair was black and it was barely past her shoulder blades. Her eyes were the same color of silver as his shined ones. She had slightly pointed ears. She wore a skin tight halter top cloth and mid calf pants. Her body was perfectly proportioned. She was built like a feminine warrior. And, flickering by her right foot, was a tail that had hair ridged around the edges like a flame.

Definitely a siren. She seemed to smile at the comment. "I've been waiting for you Lord Marshal that defies the Necro Law. Welcome, Riddick."

And then, she lunged.
