The night was cold in the Overwatch headquarter, but Sombra had grown used to it. Working in the dark was always better for her. Everything was quiet which helped her concentrate. In her mind, file were rolling around at an intense speed as she was searching for the right one. She saw, in the news, the mass shooting on King's Row, but while the police were talking about their speculation regarding a strike team from Overwatch, Sombra already knew it was Gabe. She had a grin on her face at the idea of Maximilien's death. One less threat to deal with.
She knew that harassing Talon would ultimately lead them to push Gabriel to his limit. It was only a matter of making sure the pressure was building up correctly and, in a matter of a few weeks, she had successfully turned Gabriel against Talon. Now that they were out of the way, there wasn't much between her and what she was looking for.
Of course, no one would ever know that she pushed Gabriel to do that, and no one would ever need to know about it, what mattered is that Talon was gone and she had done her job. In the morning, most Overwatch agent would sight in relief to hear it, Amélie would probably walk away and Angela would follow her. Akande would think of Gabriel and would make the connection before most others, he always knew how impulsive he could be if manipulated correctly.
She wasn't please, however, when she heard news of Los Muerto and how Maximilien managed to give her a bad name. She'll have to get back there and explain the ruse that the Omnic had been trying to pull on them. She though that stealing Morison's weapon or make a copy of it only to show it to Marco would be a way of showing she had already dealt with him, clear her name for now. But that would be for later, for she had a very specific idea in mind.
She found the files she had been looking for : the report that Gabriel sent to Maximilien regarding the guard near the temple of Anubis. Analyzing it helped her map what the outside of the temple must look like during both day and night. Their leader, Pharah, was probably going to be around during the day shift since it seemed to be the more demanding one. She would have to act during the night, which was just fine for her.
The sun started to rise up as Watchpoint Gibraltar woke up, with many of its members taking their breakfast in the room next to hers. She usually didn't interact with much people, mostly Angela and Akande, sometimes Winston when she needed access to some instruments. The rest were bearing her presence most of the time.
Angela knocked at her door, she knew it was her as she had memorized the way she knocked, and entered her room. « Did you see the news?
- Of course I did, I was awake all night.
- Who did this? I didn't know a thing about all of that.
- Gabe.
- It was him?
- You should ask Amélie about it, I'm pretty sure she knows more about his motivation than me.
- I don't know how to feel about this.
- Better rejoice. We're much safer now.
- But Gabriel is out there, and he seems reckless.
- He'll just make more mistakes then. »
She didn't seem convinced, she took a look at her monitor which Sombra made sure to turn to the news before she got in and sighted. « You're right, I'll ask Amélie about it.
- If you could bring me a drink while you're at it. »
She acknowledged and let her alone in her room. She cleared up the files in her head, stored them in their right place and stretched herself. After a night of analyzing guard tours near the temple, she was starting to feel tired.
When Angela brought her some water, she asked her to come out and join the rest of the team. « We're going to have to talk about our next plan of action, it would be best if you could participate.
- What do I have to do over there? You're all grown ups, you can do it without me.
- You've been up all night, you'll know more about the situation than us.
- Yes, and being up all night, I'm also tired and should go to sleep.
- I'll leave you for the rest of the day after that. »
Sombra sighted and got up her chair. « Alright then, let's be quick about it. »

Around a large table at the top of Watchpoint Gibraltar, Sombra joined a large group of people. Morison gave her a dark look when she entered, but she didn't bother to care. Akande and Angela were sitting at the opposite of the table, with Amélie standing further in the back, listening from far away. Morison, Torbjörn, Reinhardt and Winston were on the other side. « What's the meaning of this? Morison started.
- The council of Talon has been dismantled, Akande answered. Apparently one of them broke down and decided to kill them all.
- So they had another treason among themselves?
- Their leaders may have just fallen, but some of their agents may still be around. They are not out of the radar.
- But for now, we can concentrate on the war that actually matters. »
Morison pushed a button that showed a hologram of the globe. « The african Omnium must be our first target. It was the first one to reactivate since the fall of Numbani and to start international aggression. It is also making breakthroughs by rising north each day.
- So how do we take it down? Reinhard asked.
- We've already seen the people of Australia deal with one by blowing up the core, but it is highly radioactive and it would emanate radiation all over its surrounding for God knows how long.
- So we can't just blow it up, Angela said.
- No, but we can deactivate it. Torbjörn? »
Torbjörn scratched his beard. « Get me in and I'll do my job. I've done some research on Omnic mind with the one I rescued near Numbani, I think I'll be able to deactivate a bigger one. But getting in, that'll be your job. »
He turned to Sombra. « Getting into an Omnium like the african one is not easy. It's been active and working for decades now, unless we have superior fire power, I'll just get gunned down before getting in.
- So how do we beat it? Doomfist asked.
- I may just have an idea, » she said as she showed an electronic chip.
Winston took it and put it in the computer, which showed pictures of the temple of Anubis. « What are we supposed to do with that? Morison asked.
- In the pyramid, there is a very powerful and important piece of technology. »
Morison frowned. « You're not talking about the god-program?
- Anubis is weak, it's been taking hits from the guard around the pyramid. If I get close to it, I might just be able to shock it and take away its processors. With a tool like that, we should be able to fight fire with fire.
- You want to control Omnics? »
He seemed insulted to hear that, but Sombra didn't budge. « I'm not saying we should control them, but we could invert the signal they receive, and we should be able to at least disable them.
- You're sure you'll be able to do all of this if we get Anubis? Akande asked.
- With a little help from our engineer, we could build something interesting. I heard you have a god-program of your own in the basement somewhere in here? »
They turned to Torbjörn, who grunted. « I can't tell if she's genius or going nut.
- At least it's a plan, Angela said.
- We're talking about Anubis, Morison replied. It is a dangerous machine. Do you know how many of our men had to die just so that we could contain it in that temple?
- And now it's stuck in there pilling up dust, Sombra answered. We're not talking about setting it free, we're going to dismantle it for good and use it's strength for our own plan.
- You think we haven't already tried to destroy it? God-programs like these are all around the world at the same time, destroying it will not disable it, it will find a new place to settle in and keep growing.
- That why we want to remove it's processor. If you destroy the core, it can still grow back somewhere else, but if we remove it's strength, it won't be able to go anywhere anymore because it won't have the power to do so. It won't have the energy needed to keep control of Omnics either.
- Its processors have been gathered inside the temple, but you won't be able to get in or even touch them, there are to many of them and they are very large.
- Give me enough time and enough people to bring them back and I'll detach them. »
Angela added. « But the temple is guarded by Helix Security. We won't be able to get in unless we have their consent.
- They can let you in.
- I highly doubt it. My relation to Akande have been heard all around the world and they are hunting him down right now. »
Akande answered. « Then let Morison deal with it. Overwatch has not yet shown any public sing that they work with us.
- But Overwatch is still in a bad position, the Union doesn't officially recognize the recall of the agents yet.
- But they are the ones who neutralized Anubis, they should have the right to its confinement.
- Sadly, they lost that responsibility when it was dismantled. Helix Security has all the right to keep us out of the temple. »
Morison sighted. « We could talk to Fareeha. She may be able to get us in.
- Ana's daughter? Angela asked.
- She's the leader of the guard. She knows about me and about most of us. If you go there and try to convince her, we may be able to bypass some legal problems.
- But that would be illegal.
- That's the point, Sombra told her.
- I don't like this.
- If we want to get in, that's what we'll have to do, Morison replied. I still don't think this is a good idea, but it may just be the only plan we have right now.
- With Anubis' processor, Sombra said, the african Omnium shouldn't be a problem to deal with. We could convert Athena and let her undo the signal from the moon.
- But what do we do against the present Omnic march?
- Leave it to me, Reinhardt answered. I can hold them off with enough men, but we won't be able to do so for long.
- How much time do you give us?
- Maybe two days, maximum three.
- Is it enough? »
Sombra smiled at them. « I only need one night. Let Angela come in and bring Amélie for cover. All three of us, we'll do just fine.
- It's too dangerous to send you three alone, Morison said. There have been recent Omnic activity near the temple of Anubis. If they decide to attack, we'll need a back up plan.
- I always have a back up plan, Sombra said.
- And what is it?
- I have my EMP ready if Omnics start being a pain in the ass. Give me some time and I could prepare a bomb in case things get out of hand.
- Like the one you used in the hospital? Angela asked.
- Exactly. »
She knew Angela wasn't fond of this and tried to bring it up as a way of dissuading her, but she didn't care. She was doing her job and, with a fight against Omnics, everything useful had to be on their side.
Morison let her go, stating they had some battle planning to do with Reinhardt and that the plane to Egypt would be ready tomorrow. She got out and got back to her room and fell asleep.
