You can start the Mysteria Ecclesiae DLC by speaking with Peter of Písek, who will ask you to assist the renowned physician Albich of Uniczow. Peter can be found in Suchdol or Kuttenberg if you have already completed the main storyline. Once you accept his request, you’ll begin your journey to the Sedletz Monastery to investigate a mysterious plague.
If you own the Gold Edition of Kingdom Come: Deliverance II, Mysteria Ecclesiaeis included at no extra cost. If you have the Standard Edition, you can get it by purchasing the Expansion Pass, which includes all three planned expansions - or you can buy it separately as a standalone DLC on the platform store.
Sedletz Monastery is a major new location inspired by real history. It plays the key role in the Mysteria Ecclesiae story, offering a unique story quest line, mysteries, and an atmosphere shaped by themes of mystery and the plague.
