Riverside Manor, located in the Forest region of Appalachia, is a pivotal location in Fallout 76, serving as the secret headquarters of the Order of Mysteries. To access the underground area, you must complete the "Into the Mystery" quest, which is the first part of the Order of Mysteries side quest line. Here's a step-by-step guide on how to get downstairs:
Step 1: Find the Dead Mistress
To begin, you need to find the body of a dead mistress. There are two known locations for this:
Outside AVG Medical Center: In the alley to the right when facing the front door.
Inside the Tygart Water Treatment plant.
Loot the body for the Veil of Secrets and a damaged holotape. The holotape will trigger the "Into the Mystery" quest.
Step 2: Travel to Riverside Manor
Riverside Manor is situated in the south of the Forest region, near the border of the Ash Heap. Travel there and enter the manor.
When exploring Riverside Manor and completing the Order of Mysteries quest line in Fallout 76, keep an eye out for valuable Fallout 76 items. These items, such as rare clothing, equipment, and crafting materials, can enhance your character's abilities and provide valuable resources for further exploration and combat. Be sure to fully loot each area, including the manor's underground headquarters, to maximize your collection of these essential items.
Step 3: Explore the Manor
Upon entering, you'll notice a grand entry with a staircase leading to the second floor. However, for this quest, focus on the first floor. Explore the parlor, which is located to your left after entering the manor.
Step 4: Access the Secret Door
To reveal the secret door leading downstairs, you must be wearing the Veil of Secrets. Approach the partition in the western corner of the parlor, and it will slide open, revealing a hidden passage.
Step 5: Descend to the Underground Headquarters
Once the partition opens, proceed through the revealed door to access the underground headquarters of the Order of Mysteries. This area contains various workbenches and terminals with information about the Order.
Additional Tips
Wearing the Veil: Ensure you are wearing the Veil of Secrets when attempting to access the secret door. If you leave the area and return, you will need to re-equip the veil to access the door again.
Avoid Power Armor: Do not wear Power Armor when trying to access the secret door, as it may prevent the door from opening.
By following these steps, you'll successfully access the underground headquarters at Riverside Manor and continue with the Order of Mysteries quest line.
