The Heart of the Nora

Navigate the inner chambers of All-Mother Mountain in Horizon Zero Dawn. Discover Datapoints, solve environmental puzzles, and uncover the secrets of the Nora tribe's sacred site.

Alright, so you've made it through the first door and down some stairs inside All-Mother Mountain. Before you rush ahead, take a quick peek right next to those stairs – you'll find a Stranded Figure. Grab that, and then head down the hallway. The very first room you enter is packed with lore. Go in there to snag two Datapoints: Chamber B1-001 and [Gestation-39B1].

Back out in the main hallway, keep your eyes peeled. You'll find another Datapoint, E9B1 Incident Log A, just before you reach the next room. And guess what? There's one more waiting for you inside that room, called [Nursery-E9B1]. Keep pushing down the main hallways, and you'll find even more Datapoints scattered around: [Lesson 57-6-A], E9B1 Incident Log B, E9B1 Incident Log C, E9B1 Incident Log D, and [Kindergarten-E9B1]. Once you reach the very end of the hallway, look for a prompt to press Triangle to activate a scan. This will open up the next door for you.

Now you're in a big, circular room with a few levels. You'll notice a bunch of Datapoint markers on your radar, but here's a heads-up: they're all the same one, Welcome to the Lyceum. They're corrupted and only play a few seconds of audio. You only need to find and view one to have it logged in your Notebook, so don't feel like you need to track them all down – save yourself some time!

To keep moving forward, head down both flights of stairs from where you entered, and then go up the other two flights directly opposite you. Enter that room and scan the Operations Log Datapoint near the window. Then, grab the one in the middle of the room, Gaia’s Dying Plea, to learn some more about what's going on.

That's pretty much it for this area. Look for the door that was previously locked in this room – it'll lead you to an elevator shaft. Use the pipes and the ladder inside to climb up a floor. This will bring you back outside to the Nora. They're a bit too caught up in their traditions and are quick to start worshipping Aloy. This marks the end of this particular quest. Oh, and before you head off, you can chat with Teersa. She'll explain why Rost was made an outcast, which is pretty important background info.

You've successfully Broke the siege of All-Mother, defeating the invaders and making your way inside the sacred mountain.
