Skyrim has hundreds of hours of content, but a handful of its best quests are tucked away behind obscure triggers, unmarked dungeons, and NPCs most players walk straight past. Whether you’ve put a hundred hours into the game or you’re still working through the main story, there’s a good chance you’ve missed several of the quests on this list. Here are ten of Skyrim’s best hidden questlines, where to find them, and why they are worth doing.
1. Rise in the East
Rise in the East sends you to an entire pirate-fortress island most players never discover — hidden behind a magical fog and packed with its own self-contained story. It starts in one of Windhelm’s least-visited corners: the docks, inside an East Empire Company warehouse, where you’ll find a man sweeping the floor named Orthus Endario. Most players skip straight past him on their way to the Solstheim boat.
Talk to Orthus and he’ll explain that the East Empire Company’s Windhelm business is being sabotaged by pirates called the Blood Horkers, who he suspects are being hired by a rival group, the Shatter-Shield Clan. He sends you to break into the Shatter-Shield Clan Office and steal their ledger, which reveals their Blood Horker contact, Stig Salt-Plank. Lean on him and he gives up the location of the pirates’ secret island, Japhet’s Folly, along with the name of their leader — a mage called Haldyn, who’s the one keeping the island shrouded in fog.
From there it’s a full infiltration of a fortified pirate stronghold, ending in a confrontation with Haldyn. Defeating him dispels the fog and lets the East Empire Company move in and finish off the remaining pirates. The gold reward for pulling this off is fairly modest given the scale of what you’ve just handed the East Empire Company — make of that what you will.
2. The Ghost of Old Hroldan
This one’s Skyrim’s take on a ghost story, and it’s easy to miss because you have to trigger it deliberately. It starts at the Old Hroldan Inn, off the beaten track west of Markarth. Renting a room isn’t enough — you have to sleep in that specific room after 1am for anything to happen.
The innkeeper, Eydis, sells the room with a pitch about Tiber Septim, the first Emperor of the Septim Dynasty, once having slept there. It sounds like a scam, and Eydis’s own shock when a ghost actually turns up in the inn suggests she thought so too. The ghost believes you’re an old comrade named Hjalti and holds you to an old promise to become sworn brothers — a promise he says has kept him from Sovngarde all this time.
To complete the bond, you need to retrieve Hjalti’s sword from one of several possible Forsworn locations around Skyrim. Bring it back and the ghost finally passes on — leaving the real Hjalti, wherever he ended up, to eventually find out what’s been going on. As thanks, you get a permanent one-point bonus to your Block and One-Handed skills.
3. Kyne’s Sacred Trials
Instead of another dungeon crawl or artifact hunt, this quest sends you across Skyrim hunting spectral beasts to earn the favor of Kyne. It’s easy to miss because it starts at a small, easily overlooked cabin in the mountains southeast of Ivarstead — the kind of place you’re more likely to find by accident than by any quest marker.
Inside is Froki, an elderly hunter who’s rejected the Divines in favor of the old Nordic gods, Kyne especially. He challenges you to an old Nordic hunting tradition to prove yourself to her, sending you after a string of ghostly creatures scattered around the province — everything from mudcrabs and skeevers up to sabre cats, mammoths, and trolls. None of it is particularly hard combat; the appeal is in the sense that you’re taking part in something older than Skyrim’s current political conflicts.
The rewards are a weak bow and Kyne’s Token, an amulet that boosts bow damage and cuts damage from animals by 10%. On paper that’s underwhelming, but without the Unofficial Skyrim Patch installed, the amulet actually reduces damage from all creatures — monsters, daedra, undead included — making it considerably stronger than its description suggests.
4. Frostflow Abyss
Frostflow Abyss is Skyrim’s most effective stab at horror, and it comes with a genuinely useful permanent reward. It starts at what looks like an abandoned lighthouse on Skyrim’s frozen northern coast — remote enough that most players never wander past it.
Inside, it’s clear something went badly wrong. You’ll find the body of Ramati, the mother of the family that lived there, clutching her husband Habd’s journal. It describes Habd returning home to find her killed by chaurus that emerged from beneath the lighthouse, then descending into the basement himself to deal with the threat, locking the door behind him. A second journal, belonging to daughter Sudi, reveals that her younger brother Mani had been sneaking into the basement — meaning Habd’s lockdown trapped his son inside with him, not out.
The “basement” turns out to be a vast cavern full of Falmer and Chaurus. Exploring it fills in the rest of the family’s fate: Mani’s body near the entrance, Habd killed by a giant Chaurus Reaper deeper in, and Sudi — who was dragged down and captured — having taken her own life rather than face the same end. Recovering Habd’s remains and placing them in the lighthouse’s brazier, as his journal requested, completes the quest and grants Sailor’s Repose, a permanent effect that boosts healing spell effectiveness by 10%.
5. Forgotten Names
This one’s been sitting beneath one of Skyrim’s busiest locations the entire time. It’s found in the Midden Dark, a section accessed through the Midden beneath the College of Winterhold — an area most players pass through briefly during the College questline without ever going deeper.
Down there you’ll find a mysterious Daedric gauntlet sitting in a ritual chamber, which does nothing on its own. A nearby journal explains that a group of students tried to use the gauntlet with a set of enchanted rings to perform a ritual, and all of them ended up dead. The same journal reveals the rings were confiscated and are now stored in the College Arcanaeum, where they can be “borrowed.”
Bring the rings back to the Midden Dark and place them on the gauntlet in the correct sequence to summon a Dremora pirate named Velehk Sain. From there you get a choice: kill him for underwhelming loot, or release him in exchange for a treasure map leading to his hidden cache — which contains a substantial amount of gold and valuables, making it one of the better hidden payouts on this list. The quest gives almost no guidance throughout, which is exactly what makes finding it feel earned.
6. The White Phial
This one’s less obscure to stumble into than some of the others, but it still doesn’t feature in most playthroughs — and it’s worth going out of your way for, thanks to its characters, its twist, and its reward. It starts at the White Phial alchemy shop in Windhelm, where a grumpy old alchemist named Nurelion explains he’s spent his life searching for the legendary White Phial, a vessel said to refill any potion placed inside it. He’s finally found its location but is too old and sick to retrieve it himself.
He sends you to Forsaken Cave, west of Windhelm, with Nurelion’s Mixture in hand. Fighting through the cave and into Forsaken Crypt, you’ll defeat Curalmil and his draugr before using the mixture to access the Phial — only to find it cracked and useless. Nurelion, understandably furious, hands over an insulting 5 gold. His assistant, Quintus Navale, is more reasonable and pays properly.
That’s not the end of it, though. After finishing this quest and later progressing through The Throat of the World in the main questline, Quintus sends a letter starting a follow-up quest, Repairing the Phial. That sends you after Unmelting Snow from the Throat of the World, Mammoth Tusk Powder from Stonehill Bluff, and a Briar Heart. Repair the Phial and you fulfill Nurelion’s dying wish — after which he dies, and you get to keep the Phial. Quintus will fill it with a potion of your choice, which then regenerates every 24 hours, making it one of Skyrim’s more unusual reusable rewards.
7. The Pale Lady
You can easily miss this one entirely unless you happen across a group of bandits turning on one of their own, Eisa Blackthorn, just outside Frostmere Crypt — there’s no dedicated questline pointing you here otherwise. If Eisa survives the fight, she explains she was part of a gang hunting treasure in the ruins until a companion stole the boss’s sword and she got blamed for it. If she doesn’t survive, you can pick up the same thread from her journal instead.
Following the trail into Frostmere Crypt reveals there’s more going on than a bandit dispute. A Khajiit bandit named Ra’jirr stole the sword from the gang’s leader, Kyr, believing it was the key to banishing a figure haunting his dreams — the Pale Lady. Kyr chased him deep into the crypt over it. You’ll find Kyr dying and Ra’jirr fighting the Pale Lady herself, who turns out to be bound to the location by that same sword.
From here you get a real choice: let Ra’jirr die, loot the sword, and place it on a pedestal to banish the Pale Lady, or defeat the Pale Lady yourself and keep the sword. There are ways to save Ra’jirr instead, but he’s ungrateful enough to attack you regardless. Either way, it’s a quest that escalates fast from a routine bandit scuffle into a genuine supernatural mystery.
8. Unfathomable Depths
This one starts with a distressed Argonian, From-Deepest-Fathoms, pacing the Riften docks — desperate to offload a Dwemer Lexicon she says should never have been taken in the first place. It’s easy to miss because the Riften docks aren’t a high-traffic area, and she only appears once you’re level 14 or higher — so if you’ve already wrapped up your business there (typically the Blackbriar work for the Thieves Guild), you can walk right past her.
Take the Lexicon and you’re sent to Avanchnzel, the Dwemer ruin it was originally stolen from. As you move through the ruin, ghostly echoes replay what happened to the group that came before you: Dwarven machines attacked them, and members died one by one, each death worse than the last — which goes a long way toward explaining From-Deepest-Fathoms’ state back at the docks.
Return the Lexicon to its place in the final chamber and you’re rewarded with Ancient Knowledge, a permanent effect that speeds up Smithing skill improvement and grants a bonus when wearing Dwarven Armor — genuinely useful for anyone building a smithing-focused character.
9. Arniel’s Endeavor
This is the best reward on the entire list: a practically invulnerable summon that draws enemy attention and deals serious damage. It’s easy to miss because of how many hoops it takes to unlock — it only opens up after the College of Winterhold’s Hitting the Books quest, despite not being part of that questline itself, and progressing the Staff of Magnus quest is required to unlock its third part. On top of that, it starts with an NPC named Arniel asking you to fetch him 10 heavy Dwemer cogs without explaining why, which puts most players off before it even begins.
Stick with it, though, and the “fetch quest” turns into an investigation into one of Tamriel’s great unsolved mysteries: the disappearance of the Dwemer. Arniel’s experiments grow increasingly reckless, culminating in him striking a soul gem with the dagger Keening — one of the legendary tools associated with the Dwemer’s disappearance — and vanishing entirely.
Completing the final stage rewards you with the Summon Arniel’s Shade spell, arguably the most overpowered summon in the game, along with Keening itself to keep. The mystery of what happened to the Dwemer stays unsolved, but the payoff is worth it regardless.
10. Lost to the Ages
This is likely the most expansive questline on the list — an epic, multi-location journey with a ghostly companion, a mythical forge, a powerful bow along the way, and one of the best final-reward choices in the game. It’s part of the Dawnguard DLC but has almost nothing to do with the rest of that storyline, which is part of why it’s so easy to miss. It begins either by reading a book called The Aetherium Wars, or by finding a specific, out-of-the-way Dwemer ruin (Arkngthamz) directly.
Inside, you’ll meet Katria, the ghost of an adventurer who died searching for the legendary Aetherium Forge. Unlike most ghost NPCs, she sticks around as an actual companion — guiding you through the dungeon, letting you loot her bow, Zephyr, along the way, and leading you to the first of four Aetherium Shards needed to access the Forge.
From there, you’re sent across Skyrim to loot-filled dungeons to recover the remaining three shards. Once you’ve collected all four, you travel with Katria to the long-sealed Aetherium Forge itself. Survive the forge master and you’re able to craft one of three unique items: the Aetherial Staff, the Aetherial Shield, or the Aetherial Crown — with the Crown standing out as the best of the three, since it lets you benefit from two standing stone powers at once.
Ten quests, ten completely different reasons to go looking for them — hidden islands, haunted inns, cursed lighthouses, and an entire Dwemer conspiracy buried under a school you’ve already walked through a dozen times. If you’ve missed even a few of these, they’re worth building into your next playthrough.
