At the bottom, you’ll start noticing Maya Sundaresh is apparently in your DMs sending you creepy threats in the upper left corner of your HUD. Ignore those, and continue down the corridor on your right for some brief fresh air. Note the fancy bowl with the green hologram ahead.

These are containers for Vex Modules, which are gonna be your new best friends for the rest of the mission. Right now, you’ve just got green ones (labeled “CONNECTION”) to deal with, and the Vex will start you off with a nice and easy puzzle first. From that first container, take a right, and fight your way through a small battalion of Shadow Legion all the way downstairs till you hit a white laser wall. Once they’re all gone, you’ll just have to deal with a scattered bunch of Vox Goblins spawning every couple of minutes.

In the main chamber upstairs, you’ll notice a pillar with three gems embedded in the far wall across from the entrance, representing the three locks you’ll need to take care of to open the next path. Opposite the locks, you’ll see one of the module containers has a green beam shooting out of it. That beam means there’s a module in there to collect. Take the module, and you’ll see the way you came in is suddenly blocked off. There’s an empty green container nearby to drop it into. When you do, it’ll create a new platform with a white pillar in the center of the room. Interact with the white pillar, and that takes care of lock #1. Take back the module, and jump across the gap to the left where the Vex keep spawning. There’s another container there to drop the module into, which opens the room directly across from it, with another pillar that takes care of lock #2.
Grab the module again, drop down to the lower level, kill any Vex in your way, and drop the module in the container. This actually puts a platform in the gap, and takes down the white barrier wall. Go down the newly-opened dark corridor, and kill all the Vex in there. These guys will have a big brother, though, a Vex Minotaur labeled Independent Variable. Get used to taking down these douchebags, they’re in all the most aggravating parts of this mission, they have high HP, heavy Void shields, and they have this especially shitty habit of teleporting huge distances when they don’t feel like playing with you anymore. That’d be fine except for the fact they also tend to carry the modules you need to continue.
Anyway, take this one down—Void weaponry will at least make short work of his shields—and he’ll drop a fancy new yellow module labeled “PARTITION.” What a coincidence, there just happens to be a new yellow container in this room to drop it into. When you do, it’ll take down the barrier between you and the main chamber. Grab the green module from there, stick it in the green container in the dark hallway, which will reveal a path forward to the pillar that opens lock #3. Once you’re back where you started, grab the green module, head back upstairs, and put the module in the container that revealed the first pillar. That’ll give you the platform you can use to head into the pitch-black area ahead.
