Navigating the quests in *Kingdom Come: Deliverance 2* can sometimes feel like searching for a needle in a haystack. This guide will help you locate the Royal Treasury Key during the Oratores quest, a particularly lengthy main questline. After speaking with Rosa and Zizka, and securing Vavak's assistance with the theft, your next objective is retrieving this crucial key.
The key is hidden in an unexpected location: the outhouse in the backyard of Vavak's house. (Think of it as a less glamorous toilet.) The map below shows its exact location.

Once inside the outhouse, examine the toilet bowl. An "Investigate" prompt will appear. Interact with it, and Henry will retrieve the key. A small price to pay for progress, but be warned: this will leave Henry rather unclean. It's highly recommended to wash up at a nearby trough before interacting with other NPCs to avoid any unwanted dialogue issues.

With the Royal Treasury Key in hand, you can continue the quest by speaking with Zizka and Rosa again. Prepare for an extended adventure as you explore the underground passages with Samuel. The Oratores quest is far from over!
