Step 1: Return to the Sanctuary of Delphi

• Head back to the Sanctuary of Delphi after completing Snake in the Grass.

• The cultist torturing the other in the room beyond the rocky path to the northwest.

Step 4: Return to the Center of the Room

• Take the fragment collected in the last mission and place it on the glowing orange pyramid in the room.
• A cutscene will play, revealing the real identity of Deimos and their violent nature.

Step 5: Have a Conversation with Herodotos

• After the cutscene, have a conversation with Herodotos to conclude the mission.
