Disclaimer: Kamen Rider belongs to Ishinomori Shotaro and Toei, and KRDK belongs to Adness Entertainment. Kamen Rider Lynx's characters are her own, and the same applies to myself, Kamen Rider Raika.

AN: Now, this story here is a crossover with Lynx's Kamen Rider fanfic trilogy she's working on. I talked to her about it and the first chapter has been up for a few months now. You can go check it out on Lynx's profile, if you want to. Anyway, the plot of the story as quoted from the summary that Lynx put up:

"Sage and Arca have wound up in the Multiverse where the Kamen Rider Equips exist. Now, with Sage on one side and Arca on the other, the Rider Equips, both Dark and Light, will have themselves tested as the war of all wars begins to destroy the Earth."

So yeah, that's the plot. In this preview, Arca teams up with the bad guys, while Sage arrives at base of the good guys. I hope you enjoy it!

PS: I wrote another preview for the same story in an earlier chapter of 'Realms of My Mind,' so best read that first to clear up any confusion.

(Arca's POV)

So, I was able to convince James, the former Kamen Rider Strike, into taking me to his base. He was cautious but then again, who wouldn't be in times of war? Anyway, I followed James into the base of the Dark Riders. I assumed the base used to belong to Xaviax, the villain of Kamen Rider Dragon Knight, because it looked exactly like it from the show. In fact, I think that's what it is. Despite that, James lead me towards the main chamber of the base, which didn't change despite it was in the hands of a different owner. When I say "different owner," I mean the psycho known as Alexis, the leader of the Dark Riders.

Speaking of the psycho, she happened to be standing near a screen observing battles between her monsters and some Riders. Her back was turned so I couldn't see her face, but I could tell she happened to be wearing a long black jacket over her body. "Alexis," James called out to her.

Alexis turned around to face us. Alexis was the Earth counterpart of Kase, Kamen Rider Siren, from the Dragon Knight show. She looked exactly like her, save for the fact she was in her mid twenties, while Kase was in her thirties. Alexis looked at James, expecting her report, but once she saw me, Alexis face told me she wanted answers. "James, who's this?" Alexis demanded.

I was lucky to not go crazy in front of Alexis. Alexis was like her Ventaran twin-cunning, and a finegoodlooker! Mainly a good looker, despite she was a crazy psychopath who wanted to destroy Earth for some reason or another... and she was maybe five to ten years older than me, since I'm pretty much the same age as the kid. "Kamen Rider Arca at your service ma'am," I calmly saluted.

"Kamen Rider?" she questioned before looking at James, who simply gave a shrug. Alexis turned her head back to me. "If you're a Rider, then why does your armor look different?"

I would answer that question, but I remembered that Alexis was a sly cat, manipulative and deadly. If I gave out too much information, then she could use that against me and I didn't want to go through that. I simply replied, "That's a secret."

As Alexis remained silent, I could feel something penetrating my head. It was obviously Alexis trying to read my mind and extract whatever information she could get. Well, I am the unconscious, so that may be kind of difficult for a human to read pure thought itself. I was right as I could see beads of sweat run down Alexis' face as she finally decided to stop mentally probing me. "What (pant) are you!" she demanded in between pants.

I couldn't help but grin underneath my helmet. "What am I, doesn't matter," I replied. "Why I'm here though, does."

Alexis used her sleeve to wiped off some of the sweat. "And why would you come here?"

"He wanted to make a deal with us," we both heard James answered for me.

I turned to see him watching from the sides. I noticed he had hint of shock on his face for he saw what happened. I guess I forgot about him for a while. "Well, what deal do you want to make?" Alexis asked, crossing her arms over her shoulders.

"Simple," I stated as I looked back at her, "you give me all the information you can about this world, and I'll help you defeat the Light Riders."

Alexis raised an eyebrow at that. "That's it?"

I nodded. "That's it."

"No desire for power? No requests for a high governmental position?" she questioned. "Not even money?"

I couldn't help but chuckle. "My dear, knowledge is the most powerful thing in existence," I told her, walking up to her. "And, knowledge is something I need."

I had no idea why I talked to her like that, but it seemed to have convinced Alexis as she pondered my offer. After a few minutes of silence Alexis looked at me and said, "Alright then, you have deal."

I clasped my hands together. "Right then, when do I start?"

(Sage's POV)

I came out of the dimensional rift (the silver veil that brought me here), I found myself in an alley way. It seemed to be like any other alley. It was filled with trash and dirt, had animals crawling around and there happened to be a large, blue garbage bin on the right. I groaned in frustration, realizing Arca was probably miles away from I was.

However, I couldn't think of Arca at the moment as I heard footsteps approaching. I looked up to see the building on my right was only about five to ten feet in the air. Thinking quickly, I jumped up from the alley and onto the rooftop of that building. Fortunately there was no one on top of it, so I was safe. I quickly looked around to see where I was and I was aback at what I saw.

It looked like some kind of military base. There were gray buildings all over with a tall building in the center-probably where they keep the most information. I saw a tall, wired fence that surrounded the entire complex. The roads were made of black pavement with large army tanks and trucks on them. I noticed the soldiers happened to wearing strange uniforms and carried what seemed to be futuristic blasters. Those weapons almost reminded me of the blaster Stormtroopers carry.

Before I could examine the base even further, I heard a loud alarm go off. 'Oh man, they must've caught me on camera!' I worried.

Apparently I was wrong as I looked over the edge of the building to see soldiers who were chatting amongst themselves stop and stood to attention, their black boots against each other. The tanks and the trucks moved to the side, giving way to something. That something was a parade of military trucks that carried soldiers. From what I could see, they just were coming back from a battle, but their smiles told me they won it. After the trucks came to a halt, the soldiers came out of them, running towards their brothers-in-arms.

The moment however, was ruined when I noticed one soldier was looking up... towards me. "An intruder on the roof!" that soldier shouted, pointing towards me.

Then, every single soldier, including the Riders raised their heads to look at me. "Ah heck," I muttered.

Turning around, I sped towards the edge of this rooftop, and leaped onto the nearest one. My original plan was to head for the tall military building in the center, but with these guys chasing me, I had to first lose them. As I leaped from rooftop to rooftop, I placed a hand on my hat to make sure it didn't fly off. I heard someone shout, "Stop him!"

After that I heard guns clicking, and I immediately moved away from the edge in time to avoid a barrage of blue blasters bolts that either went flying into the air or hit the wall of the building I happened to be on. 'BAD DAY, BAD DAY, BAD DAY, BAD DAY, BAD DAY!' I thought as I avoided the blaster bolts.

After leaping off a couple of roofs, I heard the soldiers cease firing and then footsteps. That meant they were looking for me. However, they didn't know where really I was. I looked around for too see more alley in the complex. There was labyrinth of them... that lead towards the center building. They would be coming on the roof, so the alleys were the best way for me to get around.

But before I could leave, I heard, "Stop right there!"

I turned around to see who said that. It was another Rider, who looked oddly familiar. 'Ryuga?' I asked myself.

The Rider before me looked a lot like Ryuga, but the bodysuit, for one was gold. Also, this Rider had two slits on his armored back for some strange reason. He wore the same black boots on his lower legs, and black gauntlet on his right arm. However, on his left forearm was a golden gauntlet, an Advent Gauntlet to be more precise, shaped like the head of cynogriffon (a half wolf,half eagle beast) with a golden gem emblemed on its side and as well as a holster on the underside that carried cards. His helmet, which had a dark shade of gold, did look like Ryuga's, but instead of a dragon motif, it was based off of a cynogriffon just like his Advent Gauntlet.

I recognized the Rider immediately. This was Kit Taylor, the former Kamen Rider Dragon Knight/Onyx, and now Kamen Rider Cynogriffon Equip, an Advent Master of the Light Kamen Rider Equips.

I cursed myself, realizing that I appeared in the middle of a base that belonged to the Light Riders, and I attacked their soldiers. This was definitely going to put against me in court. "You're not getting away, Dark Rider spy," Kit declared before charging at me.

What? He thought I was in league with the Dark Riders? "Wait-" I began but he cut me off when he threw a punch at me.

I backed away to dodge the punch. He threw some more, which I was able to dodge. When he threw another one at me, this time I caught. He threw his other fist at me but I caught that as well. As I struggled to keep Kit's fists from hitting me, I told him, "Listen to me! I'm no spy for the Dark Riders!"

"Yeah right!" he scoffed. "How else would you have been able to get inside of this base?"

I had no idea what the heck he was talking about, and before I could think about what he said, Kit raised his right leg to kick me in the chest. I staggered back a bit, my hand on my chest armor. As the pain from the kick subsided I glared at Kit. "Don't make me do this!" I told him.

"I should be the one saying that," Kit laughed as he drew a card from his gauntlet.

"Sword Vent!" his Advent Gauntlet announced when he slid it into his Advent Gauntlet.

I saw in the distance a portal opened up in the air and a golden cynogriffon flew out of it. It was Kit's Advent Beast, Goldenheart. She (yes, she!) flew towards Kit, and a katana dropped from her body, which Kit caught. I saw Goldenheart land next to her Rider, her eyes glaring at me. "Stay out of this Goldenheart," Kit told her.

The Advent Beast simply nodded. I remembered that the Rider Equips had a telepathic bond with other Riders as well as their own Advent Beast. However, that fact would have to be ignored for now as my focus was on Kit. I grabbed my saber and activated it black blade, readying myself for any attack Kit might have.

Kit looked surprise at my saber, seeing the blade was made of energy, however, he shook it off as he charged at me. He swung his katana at my right which I blocked before laying a fist to his chest, which forced Kit back. I walked towards Kit, who thrust his katana at me, but I smacked it away with the back of my free hand before slashing my black saber against Kit's chest armor. I slashed at him again and again, each time hitting his mark. The force of my slashes sent Kit staggering back some more.

I stood there, surprised at what was going on. Kit was an Advent Master, a person capable of utilizing telekinesis and telepathic powers as well as good fighters. I thought I was going to clobbered, but I was beating him instead. "I thought you were stronger than this," I said. I didn't mean it as an insult, only just observation.

However, Kit took it as an insult as he pointed his katana at me. "Don't underestimate me!" Kit shouted.

With that said, he charged towards, slashing his katana as fast as he could. I was able blocked the first couple or more slashes that he sent at me, but the next few struck me in the chest, forcing me back. As I was forced back, I saw my hat fly off of my head and land in front of Kit. He ignored it as he charged towards me.

Anger welled up in me as I saw my hat on the ground. My hat was something I usually kept close to me, it was something that I treasured and to see it on the ground like that made me... well, lets just say angry was an understatement.

Anyway, Kit slashed his katana downward at me, but I raised my free hand to catch it. There was some pain, but I ignored it as I glared at Kit, who was taken surprised by this. I slashed my saber at his chest, which made him release his grip on his katana as he staggered back. I gently tossed the katana into the air and caught it in my other hand, while I walked towards Kit.

I first slashed Kit's katana at him only for him to dodge it, but I thrust my saber forward, hitting him in the chest. I didn't stop there as I continued to slash at him with both his own weapon and mine. I unleashed a flurry of slashes, each slash striking Kit's chest armor. After my flurry of slashes, I slashed my saber one more at Kit, which sent him flying into the air before hitting his stomach on the ground.

My anger was gone now. I stabbed Kit's katana onto the rooftop and I sheathed my saber. I ignored Kit as I walked over to my hat. "I'll be leaving now," I told Kit as I bent down to pick up my hat.

After putting on my hat, I turned around to leave, hoping to find some way out of this base. However, I felt a sudden pain in my back as I froze. "I said don't underestimate me," I heard Kit repeat.

Those were the last words I heard before I blackened out...

My vision was blurred a bit as I awoke to find myself in some room with gray walls. I could feel my head lying against a pillow and my body on a plate bed. I noticed to the side was a toilet. That was all I needed to know, for all of it meant one thing: I was captured.

I cursed Arca silently, wishing for me rip that idiot apart. However, cursing Arca wouldn't get me out of here. I turned my head towards the metallic door, which opened to reveal a soldier with a blaster in his hands. "Oh, you're awake," the soldier snarled at me.

I ignored his animosity towards me as I sat up on the bed. "Where am I?" I asked as I looked around.

"You're in a prison," the soldier answered. "I was told the Riders wanted to talk with you personally, so you'll be seeing them soon."

"Listen, you've got to get me out of here!" I told him.

"And why would I want to do that?" the soldier questioned, his hand on his blaster rifle.

"Listen, there's a dangerous man who let loose. He'll only bring ruin to your world !" I tried to explain. "I'm the only who can stop him. Just let me out!"

"Save your story for the Riders!" the soldier spat at me before closing the door.

I looked at my arms and legs. They were chained up to the wall, and I didn't have my saber. There was no window, the walls were hard to break to prevent any prisoners from escaping, and the only way out was through the door. To sum it all up, I'm stuck.

'Arca's gonna pay when I get out of here,' I swore.
