The quest for the Eye of Nocturnal remains one of the most critical milestones for any player navigating the sprawling landscapes of Cyrodiil. Whether you are playing the classic version or diving into the enhanced visuals of the Remastered edition, retrieving this stolen artifact is the only way to secure the Skeleton Key—a Daedric artifact that fundamentally alters how you interact with the game’s lockpicking mechanics. This artifact is not just a tool; it is a game-changer for thieves, assassins, and even standard warriors who are tired of carrying hundreds of fragile lockpicks.

Requirements for Seeking the Night Mistress

Before setting out to find the Eye of Nocturnal, certain prerequisites must be met. The Daedric Prince Nocturnal, the Mistress of Shadows, does not grant her audience to the weak. You must reach at least Level 10 before the followers at her shrine will allow you to summon her. If you approach the shrine prematurely, the worshippers will tell you that she demands a more powerful champion.

Locating the shrine itself is the first real challenge. It is situated in the Blackwood region, specifically north of Leyawiin. To find it quickly, follow the Yellow Road heading north out of the city gates. Once you pass Blankenmarch, look for a dirt path branching off to the west. The shrine is nestled among the trees, marked by a stone statue of Nocturnal with her signature owls.

Unlike many other Daedric Princes who require rare gems or expensive wines as an offering, Nocturnal’s requirements in the Remastered version remain accessible yet specific. Some versions of the game lore suggest a simple interaction is enough, but seasoned players often carry Nightshade—a common alchemical ingredient found near Bravil or in the inventories of mages—to ensure the summoning proceeds without a hitch. Once you interact with the statue at the correct level, her voice will echo from the shadows, tasking you with finding her stolen "Eye."

The Investigation in Leyawiin

Nocturnal reveals that her Eye was stolen by two Argonian thieves currently hiding in Leyawiin. These thieves, Wee Bam-Na and Be Jeen, believe they have kept their prize secret, but nothing escapes the sight of the Night Mistress.

Upon entering Leyawiin, your first instinct might be to confront every Argonian you see, but a more surgical approach is recommended. If you speak to the city guards about "Leyawiin" (rather than the Eye itself), they will point you toward the two suspects, mentioning their sudden and suspicious boastings about a "big score."

Finding the pair is easy; they typically reside in a house in the middle of the city, near the eastern wall. However, getting them to talk is where many players hit a wall. If you simply ask them about the Eye of Nocturnal, they will deny everything. The quest mechanics require you to eavesdrop on their private conversation.

Pro Tip for Eavesdropping: To trigger the conversation, you must be inside their house but out of their line of sight. Using a Chameleon spell or a high Sneak skill is highly beneficial here. If you stand too close, they will remain silent. Hide behind the room divider or stay in the shadows near the entrance. Eventually, they will begin whispering about their hidden stash in Tidewater Cave. Once the journal update appears, you have the location you need.

For those who prefer a faster pace, it is technically possible to skip the investigation entirely. If you already know where Tidewater Cave is, you can head straight there and retrieve the Eye without ever stepping foot in Leyawiin. This is a great time-saver for secondary playthroughs.

Navigating Tidewater Cave

Tidewater Cave is located south-southeast of Leyawiin, along the rugged coast of Topal Bay. The trek there can be hazardous, especially in the Remastered version where the wildlife scaling has been refined. Expect to encounter Kalperklan Trolls both outside and inside the cave. These creatures have high health regeneration, so bringing fire-enchanted weapons or fire spells is a significant advantage.

Once inside Tidewater Cave, the atmosphere shifts to a damp, claustrophobic environment. The cave is relatively small but can be disorienting. Follow these specific directions to find the Eye of Nocturnal quickly:

  1. The First Intersection: From the entrance, move forward until you reach the first major split. Take the left path.
  2. The Tunnel System: Continue through the tunnel, ignoring the side paths that lead to minor loot chests unless you are looking for extra gold. Follow the path as it dead-ends and turns left again.
  3. The Submerged Chamber: You will eventually find yourself in a large chamber with a pool of water. The Eye of Nocturnal is not in a chest on land; it is submerged.
  4. Retrieval: Dive into the water and look behind a leveled chest at the bottom of the pond. The Eye is a large, glowing blue jewel. Its glow makes it easy to spot even in the murky depths of the cave.

Be prepared for a fight upon exiting the water. Often, a few stray trolls or leveled monsters like bears or wolves will have wandered into the main chamber while you were diving.

The Ultimate Prize: The Skeleton Key

With the Eye in your possession, return to the Shrine of Nocturnal. Presenting the Eye to the statue completes the quest and earns you the Skeleton Key. In the context of Oblivion’s mechanics, the Skeleton Key is arguably the most powerful utility item in the game.

Why the Skeleton Key is Essential:

  • Unbreakable: Unlike standard lockpicks, which break upon a failed attempt, the Skeleton Key never disappears. You can fail a lockpicking mini-game a thousand times, and the Key remains in your inventory.
  • Passive Attribute Boost: Simply having the Key in your inventory grants a permanent +40 bonus to your Security skill. This boost makes the tumblers move much slower and stay up longer, making even "Very Hard" locks trivial.
  • Efficiency: For players who find the lockpicking mini-game tedious, the Skeleton Key allows you to spam the "Auto-Attempt" button. Since it cannot break, you can effectively force open any lock in seconds without any risk of losing resources.

In the grander scope of the game, this item is a massive boon for the Thieves Guild and Dark Brotherhood questlines, where you will encounter numerous high-level locks in restricted areas. It also saves a significant amount of weight in your inventory, as you no longer need to carry stacks of lockpicks.

Strategic Considerations and Legacy Tips

While the quest for the Eye of Nocturnal is straightforward, there are several nuances to keep in mind, especially regarding other questlines. For instance, the two Argonians in Leyawiin are involved in other local matters. If you decide to take a violent approach—which the game allows—it may impact your standing or prevent you from completing other minor tasks in the city. Nocturnal herself is indifferent to the fate of the thieves, but the city guards certainly are not.

There is also the matter of the "Blood of the Daedra" quest in the main storyline. At one point, Martin Septim will require a Daedric artifact to be sacrificed to open a portal. Do not sacrifice the Skeleton Key. There are far less useful artifacts, such as the Volendrung or the Staff of Everscamp (if considered an artifact), that are better candidates for sacrifice. Losing the Skeleton Key is a permanent setback that most players deeply regret.

For those interested in the technical side of the game, the Eye of Nocturnal is a quest item with a Weight of 0.00 and a FormID of 00026AC9. In older versions of the game, a bug involving the Skull of Corruption could allow players to duplicate the item, though this often led to game instability and crashes during fast travel. In the Remastered version, many of these stability issues have been addressed, but the core reward remains as potent as it was in 2006.

The Role of Nocturnal in Lore

Understanding why the Eye is so important requires a brief look at the lore of the Daedric Prince. Nocturnal is often considered the Ur-Dra, the eldest of the Daedric Princes. Her realm, the Evergloam, is a place of perpetual twilight and shifting shadows. The Eye is not literally a physical eye but a powerful scrying tool that allows her to maintain her influence over the mortal realm's shadows. Its loss "blinded" her to certain events in Cyrodiil, which is why she is so eager to have a mortal retrieve it.

By returning the Eye, you aren't just getting a lockpick; you are entering into a pact with one of the most mysterious entities in the Elder Scrolls universe. This connection is explored further in other titles, but in Oblivion, it serves as the definitive end-point for your development as a master thief.

Final Advice for the Journey

If you are currently around Level 8 or 9, start making your way toward Leyawiin now. Engaging in minor side quests or clearing out a few dungeons along the Nibenay Basin will quickly push you to Level 10. Once you have the Skeleton Key, the rest of the game's exploration becomes significantly more fluid. No longer will you have to turn away from a locked chest in an Ayleid ruin because you ran out of picks.

The quest for the Eye of Nocturnal is a rite of passage for every Oblivion player. It combines investigation, environmental storytelling, and a dungeon crawl that rewards you with an item you will use every single day for the rest of your adventure in Cyrodiil. Keep your torches ready for Tidewater Cave, stay out of sight in Leyawiin, and soon the secrets of every locked door in the empire will be yours to uncover.
