Starting Location: The Demon in the Dark
Find and Pull Nearby Switch
At the entrance to the cave where the quest marker appears, you find a severed robot head. The head says its name is Wren, and wants your help getting back to its body. First, turn around and pull the switch almost directly North from where you found the head.
Pick up Wren’s Head
Head back over and pick the head up off the ground.
Reattach Wren’s Head
Go inside and put the head on the robot body leaned up on the rubble.
Wren regales you with tales of times past, follow her further into the area.
Search for Alkonost
Wren says the Varkids have “gunked up her hoverjets”, so gets you to head in on your own. Proceed further into the tunnels.
Find that Incessant Beeping!
When you get to the room with all the rings, Wren knows that one of the expedition crew is in there and they start beeping. If you look on the minimap you should see an icon for an NPC on the South side of the room, that’s where Lark is.
Melee Varkid Poop
Lark is stuck in a large pile of Varkid dropping, melee it to get them out.
Deactivate Lark’s Alarm
Interact with Lark’s body to turn off the beeping.
Activate Eridian Runes: 0/3
To open the next door, you have to line up 3 rings and shoot runes through time. To do this, you stand on the 3 gold plates around the room, look at and shoot the rune on the opposite site of the room through the lit up rings.
Eridian Rune #1:
Eridian Rune #2:
Eridian Rune #3:
Shooting all 3 of those runes opens a door to the next room.
Continue Searching for Alkonost
Head farther in through the now open door, killing all the Varkids as you go and head to the final open room.
Head into the room and pick up the ECHO log off the ground.
Find and Retrieve Second Signal
Head to the opposite side of the chest in the room and grab the arm.
Something is up, go back out to the prior area.
“Find” Final Bot
The prior locked door will now be open and some Varkids will come out, kill them then head into that room.
Probably not as big as you expect, a flaming Tink will spawn. Deal with it.
Pick up Alkonost’s Head
As soon as Lagromar dies, a Badass Varkid and some Larvae will spawn into the room. Take them out, then go pick up Alkonost’s head.
Find Way Out
Head over towards the marked door.
Return Head and Arm to Wren
Grab the chests and whatnot on your way by, then head back over to Wren and speak to her to complete the mission and get your reward.
