With the knife now in your possession, exit the cave where your friends are and your objective is to now bring the knife to Citra. Fast travel to the temple and head to the marker inside for a cutscene. Citra will tell a story of the creation of the Rook Islands. As you leave the temple, Dennis will come in and say you’re going to ambush a convoy that is holding some of Citra’s people hostage. When you fully exit the temple, the mission will end and the next will begin.
