Sail to Naxos and head to the Leader House. Interact with the door and a cutscene will play. Myrrine will talk more about the player's father and sibling. Somewhere in the midst of this, Timo, her assistant, will interrupt and mention soldiers from Paros.

Follow Myrrine to the cove. Call Ikaros to tag enemies and meditate until nightfall to take them all out quietly, or go in guns blazing. The mission will end as the enemies are defeated.
