Navigating the intricate world of *Kingdom Come: Deliverance 2* can be challenging, particularly when it comes to quests like Oratores. If you're stuck on how to proceed, don't worry—we've got you covered on obtaining the Royal Treasury Key during this main quest.
Kingdom Come: Deliverance 2 - Royal Treasury Key Location
Oratores is one of the pivotal quests in *Kingdom Come: Deliverance 2*, known for its length and complexity. After engaging in conversations with Rosa and Zizka, you'll find yourself needing Vavak's assistance to execute a theft. Following this, your next objective is to secure the Royal Treasury Key to move forward in the quest.
To find the key, head to the outhouse located in the backyard, just outside Vavak’s residence. For visual guidance, I've provided a screenshot of the map below:

Once inside the outhouse, approach the toilet bowl. You'll notice an 'Investigate' prompt appear on your screen. Interact with it, and Henry will retrieve the Royal Treasury Key from the bowl. Be aware that this action will soil Henry, so it's advisable to clean up at a nearby trough before continuing. Failing to do so might hinder your interactions with other NPCs and affect your performance in dialogue checks.

With the Royal Treasury Key in hand, you can now advance the quest by reconnecting with Zizka and Rosa. This will lead you to explore the underground passages alongside Samuel. Be prepared, as the Oratores quest is quite extensive and requires patience and persistence.
That's the complete guide on how to obtain the Royal Treasury Key during the Oratores quest in *Kingdom Come: Deliverance 2*. For more insights and tips on the game, including the location of the Lower Semine woodcutters' treasure and the best perks to prioritize, be sure to visit The Escapist.
