History NightmareFuel / EndlessOcean

* Finding cursed pieces of an idol around Mo'ia Atoll causes ominous music to play briefly aboard the Gabbiano in brief cutscenes. And then you go to check your mail, and find that an email without a known source is warning you about what this will bring, warning that your hair will turn white from fear. While these emails mainly serve as a way to unlock white hair for your player, it doesn't help how unsettling they may be.

* Ship's Rest is bad enough just wandering around it at night, but then when you activate the [[ThreateningShark cutscene]], where the Magu Tapah shark emerges with a sinister laugh heard, good thing the shark doesn't attack in-game...

** Thanatos takes the cake, story-wise. He's nothing more than a KingMook CoveredInScars who's also [[PlotArmor immune to the pulsar because of his involvement in the story in-game]], but his lore, dear god... He ''kills people not because of mistaken identity, but because he knows they're human and [[ForTheEvulz it's an evil thing to kill them.]]'' His trivia entity implies that he is ''the'' [[UsefulNotes/ClassicalMythology Thanatos]], trapped in shark form and killing sailors and divers for sport. Considering Ciceros Strait is full of legendary creatures who are either literal FishOutOfTemporalWater or other spirits/gods meeting a fate like his, this isn't too far-fetched.

* When you first arrive at the Zahhab Region Depths as part of the main story. You are literally clinging to the bottom of the ocean, in the pitch black, desperately searching for the next air station, as the intense pressure is causing your air to just about speed out of your air tanks. When you find the cave you have to evict its current owner, a giant squid. And then, you find what you are looking for... The wreckage of a submersible, where the father of one of your dive partners died. Inside, you find an artifact and a letter. The father apparently spent his last moments in a cramped, non-functioning submersible writing a letter to his father, telling him that he was sorry for all of their arguments and that he still loved him, along with other heart-breaking things. It then mentions how he, when he is done writing the letter, will open the hatches to the sub and try to swim to the surface. From over a thousand feet down, where the water pressure will crush an unprotected human body into a fine paste. The game also takes plenty of time to pull you aside and explain with bright eyed enthusiasm how anything that dies in the ocean (and isn't eaten at the surface) will sink down here, to be picked apart by pill bugs the size of cats.

*** To further worsen things, Thanatos can randomly stalk the player from outside the windows in Valka Castle. [[spoiler: Kind of like the Grim Reaper stalking those about to kick the bucket.]]

* Your team's escape from [[spoiler: the Cavern of the Gods. The Song of Dragons plays at a higher than usual pitch, which causes the whales surrounding, and inside, the cavern to go berserk and start head butting the cavern walls. This causes a cave-in, naturally, but that's not the worst of it. The worst is perhaps just how unnatural the whales look. Slamming their heads into the walls like that. Repeatedly.]]

* A cutscene triggered in the Triton Village (again, at night). You see this massive shark silhouette slowly approach you from behind at the Triton Village entrance, and it keeps getting closer until its ''right next to you''. Thankfully it only turns out to be a harmless basking shark.

** Even before that: "Uh, guys, where'd Hayako go? ... Gaston? ... Oceana, [[BigNo NOOOOOO]]!"

** There are three creatures that aren't even in the encyclopedia until you've found them. These three creatures are long-extinct dinosaur-era creatures that can't even be focused on because they're outside the map. These include the sea serpent, a long-necked aquatic dinosaur, the Camerocaras, a giant horn-shelled squid... [[BuffySpeak thing,]] and the Anomolocaris, an insectoid creature with big, black, unflinching eyes.
