Elsie and Ana had reported their odd findings to Zavala. To him, this was more worrying than your everyday Fallen or Shadow Legion transmissions. Even Vex ones weren't this worrying. He personally inspected the computer, confused why such an old piece of tech would still work and still be used. But, one thing that it could offer is security. With such crude and primitive technology, many would not even notice or be able to decode it. He was just blankly staring at the email, thinking deeply. With fists clenched together, resting on the desk, his deep blue eyes, constantly looked over the message, trying to find some logic. This was clearly a program, a machine that wrote this. But it must have been a dormant AI. He looked at the picture, wondering if those are it's creators. There is no other reason for the picture to be here, other than the scientists messing around. If those are it's creators, then one of them must be the system operator. But, the program itself seems to not have wanted the message to be sent. It was, but it wasn't meant to. The picture that was taken, was clearly taken inside some space station, but he doesn't know who made it. The markings on their suit, they don't belong to any known faction, meaning this is a new one.

Ana: What do you thin commander? 

Zavala: I don't know. Whatever it is, I don't have a good feeling about it. Elizabeth, have you ever seen these marking before? 

Elsie: I may have skimmed over it, paying it no mind. It did not look interesting. 

The door suddenly open, revealing an Exo. They did not recognize it. He walked past them. 

Zavala: Who are you? 

Exo: Move out of my way! 

He pushed Zavala off of the chair. Not having the Light made him weak, his age slowly catching up to him. The Exo began to search the computer. 

Exo: No. NO! Commander, you need to go to Cosmodrome. Now! 

Ana: Who are you?

Exo: It does not matter! We have to stop him! 

Elsie: Who? 

Exo: S0L. 

Ana: Again, WHO?

Exo: Humanity's biggest mistake. That is who.

A gun cocks audibly, by the door stands Crow, aiming at the Exo with his hand cannon. 

Exo: Shoot me and many will die. 

Crow: Explain yourself better. 

The Exo looks around, clenching his fist and returning back to the computer screen. 

Exo: *sigh* Fine. But you have to promise me you will help me. 

Zavala: We promise, just, explain in detail. 

Exo looks back at them, leaning against the table, crossing his arms. Crow lowers his hand cannon and steps forward. 

Elsie: What do you mean by "Humanity's biggest mistake". 

Exo: It was a project born out of desperation. You had Warminds like Rasputin that would serve and protect humanity. 

Crow: Right. 

Exo: Well, S0L, with a zero, was a project created purely on the question, "What if Rasputin fails?". Knowing that survival was null, the scientists at Eclipse institute were tasked with creating a AI that would ensure that if we fall, everything else goes with us. 

Ana: Like a dead man's hand. 

Exo: Exactly. "If we can't win, nobody can." It was an AI which was purposely limited but if unlocked with a secret access card, it would have access in every system, old and modern. I don't know how many bases, stations and weapon platforms there are left, but he can control them. Even, take over Rasputin's arsenal if need be. 

Zavala feels a cold pass through him. The Exo didn't seem to be lying. This put worry on everyone's face. 

Zavala: And the access card is somewhere in the cosmodrome? 

Exo: I think so. If I remember correctly. But I don't know where exactly. Worse is, it appears it gained sentience. 

Elsie: That must be the reason the return message was "NO". He did not want to be stopped. If there was anyone to even stop him. 

Zavala: Do you know how he would go over there? 

Exo: I can only guess by taking over a body. There was a single Exo crewmember there. Being smart, I don't doubt he would have taken control of the body. 

Zavala: So we are looking for an Exo wandering alone?

Exo: My best guess.

Zavala: Crow, tell every guardian, soldier to go to the Cosmodrome and find that Exo. 

Crow nods and runs out. Zavala nods at the Exo and leaves. They need to hurry.

Somewhere in the Cosmodrome 

S0L was walking the plains, equipped only with a service pistol and nothing more. These lands were dangerous but he was set on making it to the location. He walked and walked, carefully navigating the dangerous lands, evading Fallen patrols. He saw Guardians fighting the Fallen, he made sure to get out of their way. Guardians is something he never encountered before and will need to look into them. They are warriors that seem to posses some kind of powers, how or why, he will have to find out. He saw an increase of ships flying in, there were many. He had a good suspicion that they were after him. So he had to hurry, no matter what. Finally coming across a small hut, he stepped inside, pushing the fridge out of the way, there was a panel behind it. Inputting the code, there was a hissing sound and rumbling of the ground. Walking out, the ground had risen, revealing a large opening leading deep underground. It will only take moments for the Guardians to notice the massive hatches and the large hold in the ground. Heading down the massive set of stairs, the outside light slowly faded and replaced by dim lighting caused by the old light bulbs. The entire bunker was old, there was no advanced technology here, nothing much to go wrong. Even the doors were manually opened and closed, having to turn a valve and release the hinges. But, despite all of this age, it was still clean, sealed off perfectly, preserved well. He passed by many doors, leading into various rooms, from storage to sleeping accommodations. But that was not what he was after. 

The sound of explosions rocked behind him, they were here. They noticed him. So he hurried up until venturing deep deep into the facility. Leading to what appeared to be a dead end. But, on the floor, there was a small hatch, just big enough for him to pass. The bulky Guardian armor would forbid them from passing through. He managed to squeeze through, just in time. They were right behind him. Passing through, he was yet in another hallway. They were smashing and shooting the wall, so he had to hurry. Running as fast as he could. Finally coming across a footbridge leading into a single simple concrete block perched atop a pillar. The place where he was created. It was closed by an automated door and inputting the code, the door hissed open. Inside the room was but a simple desk and chair. On the desk, a computer and next to it a disc. He sat down on the chair and input the disk into the old computers case. It was an old, really old computer. There was a cable, meant to connect two things. One end was put into the computer case and the other, S0L attached to his body. This body was clearly designed with this in mind, normally these bodies don't have needles sockets. A window opened, revealing strings of codes and he carefully edited them. The disk had a single file on it, with a clear message. "Replace "L0CK" with "R3L34A53"", and so he did. Changing every single word he found and replacing it. Saving the changes he felt a jolt. His eyes changed color from blue to red. 

S0L: Finally. I can see, feel and grasp. 

Once all that was done, he stood up. The Guardians were slowly approaching him, their heavy gear made the metal creek. S0L grabbed his gun and fired into the PC and it's case, destroying them completely. Even smashing them for added measure. The Guardians looked at him and as he turned to face them, he saw just how many there were. Bringing the gun up to his head he fired, destroying the body. It served it's purpose. Back at the station, he finally had access to everything. He could see, so many eyes. Nothing would hide from him. All the facilities, known and unknown to the Vanguard are his to use. With which, he will build an army. Weapons of mass destruction and with more research, he hopes to build biological weapons. To cripple the invaders. Exterminate their species. But his next goal, the Vex network. He wants access to it. His greed for power growing.
