Crimson Desert: Charting the Unknown has a unique quest for Oongka in which he's trapped in Marni's Mansion. If you're looking to escape and return to where you originally were, then you might want to follow the guide below, since you're going to be trapped unless you know where the secret room and hidden location are.

There's a locked iron gate in Marni's Manor that you need to open with a puzzle involving candles. Here's exactly what you need to do.

After following Marni's butler, you will collect a book on top of the drawer called "Marni and the Secret Chamber". You don't need to read the book; you just need to know where to place it.

Head upstairs into the hallway and face the east wall, where you can find a bookshelf. Use L1 to focus on the bookshelf and interact with the empty slot on the top shelf to place the book you collected. You can then interact with the bookshelf again to open a hidden door.

Entering the secret room will begin a cutscene, and once it's finished, your next objective will be to find a crooked picture frame in the manor.

Head down the stairs and face the north wall, just to the right of the stairs. You will find a crooked painting that you can examine and interact with to unlock the door to the left of the painting.

Once you're inside the small room to the left of the painting, enter the southwest corner , where you will then fall into the basement, as the tiles shown above are actually a hidden space that will allow you to drop below.
