Edér's personal quest

[Vastus]

Hey I was just wondering if anyone has any idea as to what triggers Edér's personal quest? I remember seeing Cohh do part of it, where you first had to talk to the Dawnstars in Port Maje and later in Neketaka. I'm already running around doing stuff in Neketaka but nothing has happened yet when I try to talk to him. Only thing I can think of is that you are locked out if you did not restore Edérs faith in PoE1, but that doesn't make much sense considering the events that relate to his personal quest were from way before he even met you iirc.
