The Grand Palace, located on the tip of Point Abele in Karnaca, serves as the residence of the Grand Duke of Serkonos. The palace is built on the ruins of the old ducal palace which was razed by Duke Luca Abele to make room for the new palace, destroying all artworks and treasures of the old palace in the process.
The palace is visited during the mission The Grand Palace, in which either Emily Kaldwin or Corvo Attano have to retrieve Delilah's effigy and eliminate Abele. It can be reached via railway coach or via boat. Both the coach station and the private docks are guarded though and the surrounding Ravina Boulevard is heavily fortified as well, closing off the city from the palace with a wall of light.
