You’re wandering through Blackreach. It’s glowing. It’s huge. It’s honestly one of the most beautiful places Bethesda ever built, but then you pick up a single, glowing red plant, and suddenly your quest log updates. You've just triggered A Return to Your Roots Skyrim players have been obsessing over—and complaining about—since 2011.
It starts with a simple curiosity about Sinderion, the alchemist who clearly had a death wish by setting up a laboratory in a city filled with Falmer and mechanical giants. But the quest itself? It's a scavenger hunt.
Thirty Crimson Nirnroot. That’s the goal.
If you’ve played Oblivion, you probably felt a cold shiver down your spine. Sinderion was the guy who had you hunting standard Nirnroot back in Cyrodiil, and apparently, he didn't learn his lesson before moving to Skyrim. Now, you're the one stuck finishing his dissertation while trying not to get smashed by a Dwarven Centurion.
The Frustrating Legacy of Sinderion’s Field Laboratory
Blackreach is a massive underground cavern. It’s basically a world within a world. When you stumble upon Sinderion’s Field Laboratory, located near the Great Lift at Alftand, you find his remains. Reading his Field Journal is what officially kicks off A Return to Your Roots.
Sinderion was obsessed. He believed Crimson Nirnroot held properties that the surface-level variety lacked. He wasn't wrong, but he definitely underestimated how dangerous the subterranean "Silent City" could be.
Most people hate this quest because it feels like a chore. You’re squinting at the ground, listening for that high-pitched, metallic chiming sound that Nirnroot makes. It’s a sound that’s both helpful and incredibly grating after the first twenty minutes.
The scale of Blackreach is the real enemy here. It’s easy to get turned around. You think you’ve cleared an area, but then you realize there’s a whole vertical layer you missed. Or worse, you find a plant, but it’s tucked behind a mushroom stalk that’s three stories tall.
Finding Crimson Nirnroot Without Losing Your Mind
There are technically more than 30 plants in Blackreach. Roughly 44 spawns exist, so you don't actually need to find every single one to complete A Return to Your Roots Skyrim style. This is a mercy from the developers, though it doesn't always feel like it when you’re stuck at 29/30 and can’t hear a single chime nearby.
Don't just wander aimlessly.
Start at Sinderion’s lab and work in a widening spiral. The plants love water, so check the edges of the underground lakes and streams first. There are several clustered near the "Derelict Pumphouse" and around the "Silent Ruin."
Wait, did you know they respawn?
Seriously. If you’re truly stuck and can’t find those last few plants, leave Blackreach. Go do literally anything else for ten in-game days. When you come back, the Crimson Nirnroot will have regrown. It feels like cheating, but considering how many Falmer arrows you've likely taken to the knee by this point, you've earned a shortcut.
The Hidden Mechanics of Sinderion’s Serendipity
Why do this? Is it just for the achievement?

No. The reward is actually one of the most powerful passive abilities for an alchemist in the game. It's called Sinderion’s Serendipity.
Basically, it gives you a 25% chance to create a duplicate potion whenever you’re at an alchemy lab. If you’re trying to level Alchemy or you’re brewing expensive Fortify Enchanting potions, this is a game-changer. It effectively increases your resource efficiency by a quarter.
For players who ignore crafting, this quest is a waste of time. For the "min-maxers," it's mandatory.
Why Blackreach is a Masterclass in Environmental Storytelling
We talk a lot about the "grind" of finding 30 plants, but we often overlook the context. Blackreach is a graveyard. It’s the remains of a Dwemer civilization that enslaved the Snow Elves, who eventually became the Falmer.
When you’re doing A Return to Your Roots, you aren't just picking flowers. You’re trekking through a silent war zone. You’ll find Revertexed servants—humans who have been enslaved by the Falmer—wandering the halls. It’s dark. It’s heavy.
Sinderion’s presence adds a layer of tragic irony. Here was a legendary master alchemist from another province, a man who survived the Oblivion Crisis, only to be killed by a stray arrow while looking at a plant.
The quest forces you to see parts of Blackreach you would otherwise skip. If you just ran straight to the Tower of Mzark for the Main Quest, you’d miss the giant glowing orb in the ceiling.
(Pro tip: Use Unrelenting Force on that giant orb. Trust me. Just be ready for a fight.)
Common Glitches and How to Avoid Breaking the Quest
Skyrim is Skyrim. Things break.
The most common issue with A Return to Your Roots involves the "piles" of Nirnroot. Sometimes, if you pick a plant too quickly after a cell loads, the game registers the pick but doesn't update the quest counter.
Always save before you enter Blackreach.
If you’re on PC, you can technically use console commands to skip the hunt, but that ruins the "fun," right? If a plant is clearly there but you can't interact with it, try toggling your view from first to third person. It sounds stupid, but it resets the interaction hitbox more often than not.
Also, don't eat the plants.
I know, you want to discover the effects. Crimson Nirnroot has four: Damage Health, Damage Stamina, Invisibility, and Resist Magic. But if you eat your 30th plant, you're back down to 29, and you’ll be hunting for another ten minutes. Wait until the quest is turned in to Avrusa Sarethi.
Meeting Avrusa Sarethi: The Final Step
Once you have the 30 plants, you have to leave the hole in the ground and head to Sarethi Farm. It’s located in the Rift, between Riften and Ivarstead.

Avrusa is a great character. She was Sinderion’s apprentice back in Skingrad. She’s the one who actually grants you the Sinderion’s Serendipity ability. Meeting her provides a sense of closure that most Skyrim side quests lack. You’re literally returning the research to his family (or as close as he had to one).
It bridges the gap between the lore of Oblivion and Skyrim in a way that feels organic. It’s not a world-shaving event. It’s just an old promise kept.
Step-by-Step Strategy for Efficient Completion
If you want to get this over with as fast as possible, follow this loose pathing. Don't worry about being perfect; just move.
- The Lab Hub: Start at Sinderion's shack. There are usually 3-4 plants within a stone's throw of the front door.
- Waterways: Follow the main river that cuts through the center of the cavern. Nirnroot is basically a weed that loves dampness. You can easily find 10-15 just by walking the banks.
- The Silent City: Head into the actual buildings. Check the rooftops and the indoor planters. The Falmer actually "cultivate" things sometimes, or at least they don't weed their gardens.
- The Heights: Use the ramps. Many players stay on the ground floor. There are several plants located on the upper stone walkways near the waterfalls.
- The Reset: If you hit 25 and you're exhausted, go to the surface, sell your loot, sleep for 10 days, and come back. The plants near the entrance will have respawned.
Actionable Insights for Your Next Playthrough
To make the most of A Return to Your Roots Skyrim rewards, you should time this quest correctly. Don't do it at level 5. You’ll get shredded by the Chaurus.
Wait until you are ready to power-level your Alchemy from 60 to 100. Once you have the Serendipity perk, every Giant’s Toe and Creep Cluster you mix has a 1-in-4 chance of giving you a "free" potion. That's thousands of extra gold and a much faster path to the "Extra Effect" perk in the Enchanting tree.
Beyond the mechanics, take a second to actually look at Sinderion’s notes. They represent one of the few times Bethesda directly linked a minor NPC's life across two games separated by 200 years. It makes the world feel lived-in, even if the plant-hunting part is a bit of a grind.
Stop sprinting. Listen for the chime. Look for the red glow. You'll be out of the dark and back in the Rift before you know it.
