Time to dive deep into the Mythic Dawn cult and grab the Mysterium Xarxes. This quest is a key part of the main storyline.
How to Start Dagon Shrine
Once you’re working for the Blades, Jauffre will point you to your next target: the Mythic Dawn’s hidden shrine.
Location: Lake Arrius Caverns, north of Cheydinhal.
Tip: Fast travel to Cheydinhal and walk from there. It’s the closest landmark.
Before heading out, it’s smart to stock up:
Visit Cheydinhal’s Mages Guild or Fighters Guild to prep or pick up some side quests.
Gear up at the local shops. You’ll want healing potions, strong weapons, and spells.
Good optional quests in Cheydinhal: A Brush With Death, The Wayward Knight, Corruption and Conscience, Swords or Stealth.
Step 1: Enter the Caverns
Head into Lake Arrius Caverns. Once inside, your journal will note that the Mythic Dawn shrine must be deeper in. You’ve got two main options from here.
Option 1: Infiltrate the Cult
Talk to the Doorkeeper. He’ll assume you want to join and let you in.
Inside, Harrow will stop you. To prove loyalty, you must:
Give up all your gear (don’t worry—you can get it back later).
Wear the Initiate’s Robe.
Follow Harrow to the main cavern. You’ll witness a ceremony where Mankar Camoran takes the Amulet of Kings and teleports away. The Mysterium Xarxes remains behind.
Proving Your Loyalty
You’ll be ordered to kill an Argonian named Jeelius as a loyalty test.
If you refuse, the alarm will trigger and you’ll have to fight.
If you agree but backstab the cult, you can free Jeelius and battle your way out.
Tip: Don’t pick up the Mysterium Xarxes until after freeing Jeelius. Grabbing it causes a statue to collapse, which can kill him.
Option 2: Go Loud
Skip the deception. Just storm in and fight everyone.
You’ll face Mythic Dawn Agents, Acolytes, and Guards.
If you gave up your gear earlier, it can be looted off Harrow after defeating him.
Both paths lead to the same goal—getting the Mysterium Xarxes and escaping.
Step 2: Escape the Shrine
Once you have the Xarxes:
The main entrance will be barred.
Look for a northern exit leading to the Living Quarters.
Fight through more enemies. Near the end, a hidden lever opens a secret passage back to the cave entrance.
Saving Jeelius (Optional)
If you free Jeelius:
He’ll flee the shrine and survive.
Later, find him at the Temple of One in the Imperial City.
He’ll reward you with +1 Alchemy, Mysticism, and Restoration.
Step 3: Report to Cloud Ruler Temple
After escaping:
Head back to Cloud Ruler Temple.
Give the Mysterium Xarxes to Martin. He’ll begin studying it.
Speak to Jauffre to move on to the next quest: Spies.
Final Blurb
Whether you sneak in or smash down the front door, taking the Mysterium Xarxes from the Mythic Dawn is a turning point in the Oblivion Remastered main quest. And if you saved Jeelius? Well, that’s just a bonus. Time to see what secrets Martin can pull from that dangerous book.
