There's a chunky hole in the lava zone that you have to go down, and you find her facility. Not going to spoil the game, but you need a few things along the way first.

Yes you have to go deeper

In the deep dark down deep dark

The sea emperor is a vital part to the story line and you find it near the very end of the game

You're close if i think where you're at.

I think they might be, I saw them in an earlier version of below zero but they might’ve been removed

They switched up the story so the emperors are gone from BZ as far as I’m aware

Technically yes, since its in the same world.

But for BZ, ive yet to notice them or hear about them in it.

I think they were removed because the old storyline needed the enzymes, but the new one doesn't. I wouldn't be suprised if they added them back in tho. When they were in, I think there was 2 in total.

Yeah I believe they’ve been temporarily removed.

They used to have a voice line asking you if you’d come to play the first time you swam past one.

I have seen this before, once they are let free they grow and you can find them in certain places around the map. I was so terrified when I first saw the biggest shadow I’ve ever seen, but then I looked up and saw it.

Yea once they are freed they spread around the world and grow up and there is a page on the fandom about the locations of your curiosity gets the better of you

Once you set them free they roam around the map, Ive come across them a couple of times in various places, one even yeeted away a couple of bonesharks that were having a go at my seamoth!!

Do you mean dragon?

If you already released them, then they will grow to juveniles and swim around some places (that’s the case I think)

I would imagine the void. She looks like she'd be able to fend off ghost leviathans, and she presumably eats plankton?

It could've also been the impact of the ship that destroyed everything there. We can't really know for certain. In the case that the biome(s) there was(were) destroyed I don't think it would've been deep enough for the emperor's to thrive in.

According to the PDA, she would live in herds in the void, and come to the shallows for feeding on microscopic organisms

I could imagine with it being the biggest leviathan, the void would be the only suitable option in a matter of size. But if we consider what we need to make the eggs hatch, it could be possible that they were wandering around all biomes and didn’t have a specific biome to live in (which would make the life in captivity even more cruel).

maybe the crash zone was an extension to the safe shallows and she lived there? It is quite a big biome

I think there's defo some lingering questions that will need to be addressed and resolved in 2.4+

IMO, I think the horse /is/ the Sentinel and the Imperator, but maybe everytime we've talked to Imperator, it has actually been the Threnodian talking? they were merged together for so long, maybe the Threnodian has been playing the Imperator like a Puppet. and now they've been released or something and are hiding inside of Cartethyia, waiting to re-emerge ?

The Cetus/Imperator connection is explored more along the "Old Man and the Whale" event that Kuro made permanent (minus the special rewards). In one of the questlines, Phoebe translates ancient tablets detailing how Cetus was originally a guide for souls killed on the sea into the afterlife. However, Cetus would rage and cause immense storms, so Imperator built the Lighthouses to calm him and named him guardian of the seas and master of marine life.

I may not be using the exact terms, but the reveal is after you get the last lighthouse lit through the three gifts to the ghost at the crab shrines.

Dive into her aquarium and scan things there

Yup it eats you and you die

The end will be very clear, not something you can accidentally cause to happen. Hope you're enjoying the game.

Nope, that isn’t the end. Even creating the cure isn’t the end.

Amazing thank you so much 😁

If you find the sea emperor you're about 80% done. To find her, you've explored pretty much the whole map, and you feel pretty comfortable with the game. But there's still more to do- remember your objectives still stand of dealing with your infection and escaping the planet.

I bet they haven’t shown Rathalos yet because they’re gonna show an interaction between Lagi and Rathalos just like they did with Nerscylla and Gypceros.

Praying for some unknown monsters… just ONE

Look forward to your collection of findings, rose!

The leak train is back on the station

I didn't think Shiiwu would have a shell, due to both how small it is, and after seeing the mantle(?(the big bulb thing)) on the back of Nu Udra, but it's nice to have some concrete information about this thing's biology. I'm now curious though as to where the weapons and armour get the gold from, maybe a beak or small hooks on the arms?

Lot of breeding and consuming their young? Or maybe there used to be a lot more there that they already ate. Sea emperor being the sweetheart she is may have let them have a nibble every now and then from her. Most likely scenario though is >!that the aliens that went digital found a way to sustain them all, most likely through the peeper vents or some alternative food source!<

There are peepers going in and out through the vents and they may very well serve as food. Am I wrong about that? Surprised that other replies do not mention it at all when it's a big part of the story

Shedded skin from the emperor is my head cannon

By the power of friendship

Maybe they will eat some old peepers
