Note: For this questline, you will need 35 Fragment of the Source and 6 Insignia of Vanya. If you are doing this in a team, then only one person needs to collect the 6 insignias. You can choose whether you want to collect these parts before or during your quest. Most mobs seem to have a decent drop rate of fragments and insignias, though sided mobs and dyna bosses in Penumbra drop them a little more frequently.
To start this questline, you need to talk to Devoted Cama Gil-Lux. You will find him in the NW Redeemed temple (921x2055). To find him in this temple, run into the second room, take the stairs up and enter the room on the right. You will find him on the right side on the small platform.
