• Ghost: Lord Saladin, you said the Fallen already knew about SIVA, but I can't find a reference to SIVA in the Vanguard database.
• Lord Saladin:That's because I went to great lengths to lock it away. The records are in the Iron Temple.
• Ghost: Okay, but if the Fallen already know about SIVA then shouldn't we?
• Saladin: What you need to do now is track Sepiks. If we find him, we will know the extent of the corruption.

Guardian arrives at Old Russia.

• Ghost: Okay I don't know which scares me more; the giant Ketch, or whatever took a bite out of The Wall.

The Guardian engages a Fallen force Guarding the entrance to the Wall.

• Shiro-4: Guardian, it's Shiro. You're gonna need some cover, make for the Cosmodrome.

• Ghost: We need to get through that wall.

• Shrio-4: With most of the Kells gone, getting a full force this large to work together is almost impossible.

• Shiro-4: Saladin, you mentioned a sensor grid. Can we use that to tell how far this occupation extends?

• Saladin: The Fallen are irrelevant, Shiro. The only thing that matters now is finding Sepiks.

Guardian encounters more Fallen inside The Breach. They are eliminated.

• Ghost: Lots of Fallen, but still no sign of Sepiks.

Guardian continues into The Divide

• Ghost: What is that pattern over there, can we take a closer look?

Ghost scans pattern

• Ghost: I am picking up some strange readings. It's like what was on Sepiks, but if I didn't know any better I'd say this stuff is consuming everything around it.

• Saladin: That is SIVA. With the proper direction, could create anything a civilization would need. At least in theory.

A Hive warship appears.

• Ghost: Hive?

• Saladin: The Hive tend to keep to the dark. Something is driving them into the open.

Guardian engages and eliminates Hive soldiers before heading for the Rocketyard. Once there, the Guardian clears out the inhabiting Hive before proceeding to another hive infested region. They are eliminated

• Shrio-4: I just lost all readings from the Sensor Grid. There's a monitoring station near your location, hook into it and try to get the Grid back online.

• Ghost: No problem.

Guardian enters a SIVA infested facility before reaching the monitoring station which is barely operable.

• Ghost: Um, there's not enough left of the Sensor Grid to fix. Wait, we can pull the logs from the monitoring station. Would that be enough to figure out what these Fallen are up to?

• Shiro-4: Do it.

Fallen appear, and begin attacking the Guardian.

• Ghost: Something weird incoming. These Fallen are different. They're augmented with some sort of technology like Sepiks.

• Shiro-4: Augmented or not, we need that sensor data.

More Fallen appear.

• Ghost: There's more of these machine Fallen inside.

Guardian kills the additional Fallen.

• Ghost: I got everything I could out of the Sensor logs.

• Shiro-4: Nice job Guardian, but we still have to deal with Sepiks.

• Saladin: We no longer need the Servitor Shiro. I've seen enough to know the Fallen have restarted production of SIVA. Guardian, we've established a base at the Iron Temple. Join us here.

Walkthrough

After the cutscene, you will find a giant Ketch and a destroyed wall in front of you. As you start moving towards the marked location, you'll encounter a good number of enemies nearby guarding the wall. As these are Level 42 enemies, we can easily take them down one by one. If you still having trouble then try taking cover behind the rocks to regenerate some health.

Get inside the Broken Bridge and get ready to face some more enemies all the way through the tunnel. Move slowly as the Dreg are very smart and hide behind the walls, either use grenades to shot a fire to make them jump out. Take them down and head towards the second tunnel which is the exit towards the new area - The Divide.

Investigate the Pattern

As we see there are no signs of Sepiks and it's all surrounded by the Fallens. Try to Scan the pattern which is a Red wire thing which is consuming everything around it just like SIVA. You must find the root which is the sensor grid, but first, you need to deal with a Hive which will soon drop by and start spawning the Fallens. Along with regular Dregs and Vandals now there are Wizards and Acolyte joining their clan.

Activate the Sensors and Eliminate the Fallen

Once you Activate the Sensors, quickly climb up the stairs behind to take cover. The Fallen now spawning will be augmented and even Lord Saladin has no idea about the corrupted enemies. Defeat all the mutated Fallens inside the Monitoring room to complete the mission. You will be facing Splicer Vandal, Splicer Captain, and Splicer Dreg which are more powerful and upgraded.

As soon as you Defeat all the augmented Fallens and let Ghost collect all the data from the Grid. Thus completing the mission and continue to the next chapter - The Iron Temple and The Plaguelands.
