The Hornwright Industrial Headquarters is a significant location in Fallout 76, situated in the Forest region of Appalachia. It is a central hub for several quests, including "The Motherlode" and "Division of Wealth." One of the intriguing aspects of this location is the mysterious area known as "The Cave," which requires a specific ID card to access.
Location and Layout
The Hornwright Industrial Headquarters is located south of Charleston Station and east of the Charleston Trainyard. The building is a multi-story structure with a total of 12 floors, although entry is typically gained via the 5th floor due to the building's state of disrepair.
Quests and ID Cards
To access certain areas within the headquarters, players must acquire specific ID cards. For example, to reach the upper floors, including the executive levels, players need to obtain a Senior Executive ID Card. This card is obtained by completing the Hornwright Industrial exam in the Human Resources Department, which involves becoming a Corporate-level Executive.
However, accessing "The Cave" requires a different approach. The Cave is part of the "Division of Wealth" quest, where siding with the settlers over raiders allows access to this area. The ID card needed for The Cave is provided by Paige during this quest, enabling players to navigate through security grids and reach Penelope Hornwright.
In Fallout 76, exploring locations like the Hornwright Industrial Headquarters can be rewarding not only for the narrative but also for gathering valuable resources and equipment. Trading Fallout 76 caps for items or purchasing upgrades at traders scattered throughout Appalachia are common practices among players. The experience of navigating through areas like The Cave, with its intricate puzzles and strategic gameplay elements, often leads to discovering hidden caches of caps, weapons, and other vital supplies. This hunt for resources makes each visit to the Hornwright Industrial Headquarters an exciting adventure filled with discovery and strategic planning.

The Cave and Its Significance
The Cave is a unique area within the Hornwright Industrial Headquarters, accessible via an elevator that leads to a curved hallway ending in a locked door. This door requires a specific ID card, which is not the standard executive ID card used for other areas of the building. The Cave plays a crucial role in the "Division of Wealth" quest, involving interactions with Penelope Hornwright and navigating a maze-like environment known as the Motherlode Test.
Conclusion
The Hornwright Industrial Headquarters in Fallout 76 offers a rich experience with its quests and hidden areas like The Cave. Understanding the different ID cards and how they are used is essential for progressing through these quests. Whether you're exploring the ruins for resources or delving into the mysteries of The Cave, the Hornwright Industrial Headquarters remains a compelling destination in the world of Appalachia.
