Three fireteams of three had been gathered to eliminate the new and improved Walker in the Plaguelands. The first team was fireteam Zeta, but there was fireteam Alfa and Beta accompanying them. The nine guardians came to the lands, to take out the threat. 

Sarc-4: Where the fuck is it? It can't have just gotten away, could it?

Lenka: It is vastly more maneuverable than a normal Walker. Let me contact the others, to see if they saw it. Fireteam Alfa and Beta, do you copy? 

Lato-12: Fireteam Alfa, we copy. 

Lenka: Fireteam Beta. 

She waits and waits but there is no confirmation. 

Lenka: Alfa, regroup on Beta's last known location. We will be there shortly. 

They got onto their sparrows, driving to the last known location. They pass by many destroyed tanks and IFVs, even helicopters. Some of their own doing some of the Maya's forces. They were worried, if the Walker got to fireteam Beat they might have been wiped out. That thing is far more dangerous than any Walker they faced up till now. As they approached the coordinates, they saw Fireteam Alfa standing by a ledge. As they got off of their sparrows they stepped forward. 

Ilias: Any news? 

Mike: Nothing. Apart from this. 

Mike opened up his fists, pieces of a destroyed Ghost. This sends a chill down their spines. 

Sarc-4: Fuck. Whose is it? 

Martin: We don't know. Could be either of theirs. 

They hear a mechanical roar and ground shaking. Over the crest behind them, the Walker appears. 

Sarc-4: Shit, jump down. 

They run for the ledge and jump off just in time as the Walker fires it shot. They run for cover, aiming up at the cliff as the large legs are the first thing they see. The Walker crosses over the ledge and digs it's legs into the cliffside. They open fire, aiming for it's legs, the usual weak point of the Walker, but this one is different. Their bullets do nothing to penetrate the armor. With a single shot of the cannon Mike and Martin are killed but soon enough revived by their ghost. The group jumps on their sparrow, heading for nearby ruins, hoping to get at least some advantage there. Out in the open, they are easy prey. 

Martin: How the fuck is it that fast?! 

The Walker is moving quicker than normal at them. They see missiles fire up into the air, homing towards them. They maneuver, managing to evade them in time. As they get closer, more rockets are launched, thankfully, before they could impact they get into cover. They hit the concrete and explode upon impact. 

Sarc-4: Folk, spread out, get into different positions. It can't shoot at all of us at the same time if we are spread out. 

They all nod, quickly running around, finding a suitable position and hiding and waiting. Their hearts beat loud and hard as they hear it approaching. Once in sight, Sarc was the first to emerge, casting his Gathering Storm staff, It hits and sticks to the metal body of the, constantly pulsing with Arc energy. The others join in, firing and casting their suppers. But as the dust settles, bright blue glowing eyes can be seen, piercing through. 

Mike: What the fuck! How is it still fucking alive?! 

Lenka: Just keep firing! 

With the complete focus on the Walker, they fail to spot a Psion that had climbed on a nearby ledge. On his armor, the same symbol that Ana found in the bunker. It was equipped not with a usual Cabal made rifle, but a large sniper. It had a drum magazine and a gyrojet underbarrel stabilizer that offers all the advantages of a bipod but without the drawback. It does not need to be deployed on the ground, offering easier use and quicker engagement times. It aimed at Mike and fired, hitting him in the head, killing him instantly. With his Ghost exposed, he fired a follow up shot. The bullet pierced the Ghost's shell, from the Ghost, a explosion of Light energy expanded. The battlefield silent, the Guardians exchanged glances at the sight. Third shot rang out, Martin was hit and his Ghost suffered the same fate as his teammates. The others ducked for cover quickly. 

Lato-12: Fuck! No! Martin, Mike! Noooo!

Sarc-4: Who did it? 

Lenka: There, on the ledge. 

The Psion stood up, resting the rifle on it's shoulder. It pulled out a knife and engraved two lines on the rifle and simply walked off. 

Ilias: Who was that!? 

Lato-12: I'll kill him.

Sarc-4: That will have to wait, for now, retreat guys. We can't win, there is no way. 

A ship flew in and hovered above their position. A Titan appeared before them. 

Ilias: Who is that?! Oi, it is not safe. We have to retreat! 

Lenka could not believe her eyes. It was him, the living legend. And her idol. 

Lenka: The Nameless one. 

Sarc-4: Who?

Lenka: The best Guardian to have ever lived. If he can't do it, nobody can. 

Guardian: You two, go to the right side, you two, to the left. 

The group nodded, Lenka and Lato heading to the right whilst Ilias and Sarc went to the left flank. The Guardian began to fire his Sweet Business into the Walker, with his Actium War Rig he unloaded endless rain of bullets. The others, once in position unloaded their rifles. The Guardian charged forward, putting the Sweet Business on his shoulder. He evaded and took bullets directly. Hiding only to recover and then charge again. 

Sarc-4: What the fuck is he doing!? Is he stupid?!

Lenka: Just, trust him. I know that whatever he does is not stupid, but calculated and thought-out. Just, support him. 

She casts her Chaos Reach, distracting the Walker. The cannon swings towards her and she manages to land on the ground before it hit her. The shell whizzed above her as it flew past. The Guardian jumps up at the Walker, climbing onto it's body and grabbing a hold of the cannon. It hold on as the Walker tries to get it off. He grabs a shrapnel grenade and lodges it down it's barrel, pushing it deep inside. He, with a lot of effort manages to tilt the cannon up, further pushing the grenade inside. As it explodes, not only does it blow up the shell in the breach but cooks off the rest of the shells that are in the feeding system. The explosion is so large that it wipes out all of them, destroying the structure which they were hiding behind. As they are revived they stand there. The Walker's corpse missing it's entire back half. It's legacy over. 

Sarc-4: Ha. Haha..Hahahahha. The motherfucker is dead! Hahaha. 

Lato-12: The crazy son of a bitch did it. 

Lenka watches in amazement at the Nameless Guardian, her cheeks blush. Her hero, her idol right there, saved her from certain death. 

Lato-12, once the high of victory disappears, looks back at where his teammates once stood. Ilias places a hand on his shoulder. 

Ilias: We will find him and you will have your revenge. 

They see a naked plain Exo approach them, clapping. 

S0L: Bravo. Bravo. Well done Guardians. 

Sarc aims at the Exo. 

Sarc-4: Who are you? 

S0L: Oh, me, that does not matter. But I got what I needed from all of this. Though, I must ask, why do you fight it? 

Guardian: Fight what? 

S0L: Me. 

Lato-12: Who are you again?

Guardian: S0L. 

Everyone quickly aims at S0L, their fingers on the trigger, ready to pull. 

S0L: You know well that won't do anything. But, tell me, why do you fight me? I could offer you a new Golden Age. Free you from the shackless you are head down by. 

Guardian: We know that the freedom you offer is no different than what The Witness offered us. 

S0L: How so? I will not destroy you, nor the world, if anything, I will improve it. 

Guardian: You will kill every single thing to achieve that, even humans. 

S0L: Casualties are expected. There is no progress without them. It is how things work. 

Lenka: We will not let you hurt our friends and allies. We can handle ourselves. 

Guardian: You offer only salvation to humans who take your hand...

S0L: That is correct. No fool would push away a helping hand. Call it, natural selection. But I must say...

S0L looks to the horizon. 

S0L: Psion's have proven themselves useful. Smart people, easy to cooperate. And, Eliksni, interesting people. I have taken some under my wing, offered them my technology and in return, I got their brains and many Brig's and Walkers. 

Lato-12: That Psion, that killed my friends...

S0L: Yes, quite a capable one, isn't he. I do feel so...

Lato pulls the trigger, emptying the entire magazine of his rifle into the S0L's Exo body. 

Guardian: That complicates things. 

Sarc-4: He seems flexible. 

Guardian: That is the most worrying thing. It shows that he now has free will. If he forges alliances with those who are looking for a leader, it might became really problematic. 

The Guardian's radio crackles as Zavala contacts him. 

Zavala: Guardian, we need you in the ruins of Moscow, now! Ana discovered something terrifying. 

Guardian: Understood. 

The transmission cuts. 

Guardian: You are coming with me. 

The group nods and jump into their ships. Heading out towards Moscow.
