Travel to the secluded Sedletz Monastery and uncover the mystery behind a deadly disease in Mysteria Ecclesiae, the third story expansion for Kingdom Come: Deliverance II.
A sudden epidemic has struck the monastery - resources are scarce, tensions are high, and every shadow could hide a threat. As Henry, you’ll take on the role of investigator, piecing together clues to uncover the truth behind the outbreak.

Explore the haunting beauty of Sedletz, meet its secretive inhabitants, and test your sleuthing skills in a cinematic questline filled with choices and consequences. Discover new gear, weapons, potions, and books - but beware, not everything in the monastery is as it seems.

Mysteria Ecclesiae launches on 11 November 2025 and is included in the Expansion Pass and Gold Edition.
Add to your wishlist now and be the first to uncover the monastery’s secrets.
