Finding the Royal Treasury Key in Kingdom Come: Deliverance 2's Oratores quest can be tricky. This guide provides a clear walkthrough.
The Oratores quest, a lengthy main quest, requires retrieving the Royal Treasury Key after assisting Vavak. The key's location is cleverly hidden.
To obtain the key, locate the outhouse in Vavak's backyard (see map below).
Inside, examine the toilet bowl. An "Investigate" prompt will appear. Select it, and Henry will retrieve the key. Be aware: this will dirty Henry. Clean up at a trough before continuing to avoid dialogue issues with NPCs.
With the key, return to Zizka and Rosa, then explore the underground passages with Samuel. The Oratores quest continues after this point.
