Hogwarts Legacy delivers a beautifully realized wizarding world filled with ancient magic, environmental puzzles, and hidden milestones across the Highlands. Among the various side challenges that charm players early in the campaign is the Cache in the Castle quest given by Arthur Plummly. This specific treasure hunt tests your observational skills as you decode a hand-drawn map to track down unique landmarks scattered inside the massive school grounds.
Starting the Cache in the Castle Side Quest
To initiate this journey, you need to speak with Arthur Plummly near the Charms classroom in the Astronomy Wing. He will share a mysterious treasure map detailing three distinct landmarks hidden within the historic building. Exploring these specific spots provides deep historical context regarding the ancient architecture while leading you directly to a unique wardrobe reward.
Understanding the layout of the school helps minimize unnecessary wandering during this puzzle. Arthur is eager to see if anyone can crack the illustrations, making this a perfect opportunity to explore the local surroundings. Once you accept the parchment from him, the mini-map tracking icons disappear, leaving you to rely purely on visual clues.
Tracking Down the First Two Visual Landmarks
The initial illustration on the map depicts a large rhinoceros skeleton situated inside a well-lit corridor. From your starting position, descend the nearby spiral staircase until you reach the Defense Against the Dark Arts tower. You will easily spot the massive skeletal exhibit resting along the wall, which triggers the next objective phase automatically.
The second clue points players toward a beautiful fountain shaped like a dragon sitting in a central courtyard. Head out the nearby doors into the Transfiguration Courtyard to locate this large stone structure. Approaching the stone beast satisfies the secondary condition of the quest layout and sets up the final puzzle solution.
Solving the Painting Secret and Claiming Rewards
The final landmark on the map guides you through the nearby double doors and up a short flight of stairs to find an ornate painting of a snow-covered house. To reveal its secret hidden mechanism, you must cast the Accio spell on the handle at the top of the frame. This interactive trigger causes the painting to open like a door, exposing a hidden alcove directly behind the canvas.
Inside this compartment rests a small chest containing the highly sought-after Authentic Historians Uniform appearance modification. After collecting this legendary cosmetic piece, return directly to Arthur Plummly to share your successful discoveries. Completing this final conversation completes the quest line, granting you additional experience points for your wizarding collection.
