The main door in the Entrance Hall is locked. To open it, you'll need to find three specific crests: the Serpent, the Horse, and the Eagle. These crests are located in various rooms branching off from the Entrance Hall. Each crest will require you to solve a small puzzle or navigate a short, dangerous section. Once all three crests are collected, return to the main door and place them in their respective slots to unlock it. This will grant you access to the Guest Room and beyond.
