Chateau d'Onterre is a side quest in Dragon Age: Inquisition.
What exactly happened in the long-abandoned Chateau d'Onterre is a bit of a mystery. Perhaps exploring its darkest corners will uncover some truth—or treasures.
Acquisition[]
Obtained by entering Chateau d'Onterre.
Walkthrough[]
Head to the Formal Gardens (the area located in the center of the ground level) and use the search function to find Codex entry: Sketch I of Chateau d'Onterre Interior which identifies the next location you need to find to solve the mystery of Chateau d'Onterre. The location of Sketch I is identified on the Sketch of Chateau Courtyard if you have previously found this.
Undead will start to spawn and will increase in number as you progress the quest. You will also find notes and diary entries that will allow you to piece together the story behind what happened the Chateau.
Return to the Gallery (bottom right of the ground level) and head up the main staircase. Turn around to find the bust statue overlooking the staircase. Interact with the statue to find the next clue, Codex entry: Sketch II of Chateau d'Onterre Interior.
Head west through the Library and north into the Bedchambers hallway then into the second bedchamber on the left. Interact with the painting to retrieve Codex entry: Sketch III of Chateau d'Onterre Interior. Retrace your steps back down the gallery staircase and up the stairs past the Servant's Quarters (top left side of the map).
Through the Antechamber you'll find the upper level of the Ballroom and the next part of the puzzle under the lion's head statue on the other side of the dragon bones. Interacting with it will cause the dragon's tail to straighten. A note and a balcony key will be found there.
Unlock the balcony on the bottom right side, defeat the undead and access the room behind the locked door to loot some notable items. Interact with the glowing box to gain a permanent increase of +10 to the Cunning attribute of the character interacting with it. An Arcane Horror will spawn in the Formal Gardens below. Defeat the demon to complete the quest.

Notes[]
- Prior to Patch 1.5 the Arcane horror also dropped an Amulet of Power (Cole)
- If Cole is with the Inquisitor when they first enter Chateau d'Onterre, he will say things such as "It knows we are here."
- This quest may be a reference to the myth of Pandora's Box. The demon manipulating Lord D'onterre's daughter is referred to with feminine pronouns - a rarity outside of desire demons - and upon the opening of a box gifted to the girl, releases horrors upon the chateau's residents.
- Another, less likely, possibility is a reference to the Hellraiser franchise, given the box's similarity to the Lament Configuration puzzle box and the fact that it releases a demon when interacted with, similar to the summoning of the cenobites.
