Your character or someone in the group must have unlocked all three levels of the dungeon.
Starting the Quest[]
Enter Nektropos Castle and find the room of Pelleas ( -36, 0, -57 ) Copy/waypoint -36, 0, -57.
Examine the family portrait on the table against the wall near the bed. If the portrait isn't on the table, kill Pelleas and wait for a personal attendant to enter the room and place it there. If the wandering personal attendant was previously killed then the portrait will not be delivered. A possible workaround is to zone out and then zone back into Nektropos Castle. The quest will NOT be offered at this point...but you MUST do this before the next step.
Head to Crysta's Bedroom at ( 57, 13, -78 ) Copy/waypoint 57, 13, -78 (same room as the paintbrush below). Click on the painting above the dresser. You will get the quest after you complete the dialog.
Steps[]
Search for clues about the six daughters in the painting:
Paintbrush -- Examine the blank canvas on the easel in Crysta's Bedroom (other side of the bed). ( 52, 13, -87 ) Copy/waypoint 52, 13, -87
Heart -- Examine the large mirror on the wall in Sheila's Bedroom. ( 70, 13, 8 ) Copy/waypoint 70, 13, 8
Wrench -- Examine the broken container next to the dresser in Melanie's Bedroom. ( -45, 13, -86 ) Copy/waypoint -45, 13, -86
Leash -- Examine the leash on the wall in Jenni's Bedroom. ( -74, 13, 6 ) Copy/waypoint -74, 13, 6
Flower -- Examine the shovel leaning against the wall in the basement of Deirdre's Bedroom. ( -44, 0, 85 ) Copy/waypoint -44, 0, 85
Sword -- Return to the courtyard and examine the doll on the floor near Master Eldin Necrosis to update Elise's clue. ( 11, 0, 31 ) Copy/waypoint 11, 0, 31
Find the other five dolls of the Everling sisters in Nektulos Forest; doll respawn is 20 seconds:
Crysta's rag doll is in Camp Leeot to the west of N'Mar's Ascent ( 135, 65, -1472 ) Copy/waypoint 135, 65, -1472.
Shiela's rag doll is in the Citadel of Gul'thex, third floor, top of tower ( 700, 23, -708 ) Copy/waypoint 700, 23, -708.
Deidre's rag doll is at Behemoth Pond ( -212, 6, -282 ) Copy/waypoint -212, 6, -282.
Jenni's rag doll is in the western bear cave ( -1381, 29, -701 ) Copy/waypoint -1381, 29, -701.
Melanie's rag doll is near the entrance to The Obelisk of Lost Souls ( -86, 92, -2226 ) Copy/waypoint -86, 92, -2226.
"There must be someplace that hints of the use of these rag dolls." Go to the basement of Nektropos Castle and enter the secret research laboratory by examining the sconce on the wall at ( -8, -14, -18 ) Copy/waypoint -8, -14, -18.
Examine the six circles on the floor to place the six dolls of the Everling sisters.
Harvest The Idol of Everling that appears on the floor in the center of the circles.
If you have trouble harvesting the idol, try crouching and harvesting in first-person view or standing behind the idol with your back to the wall.
If you cannot click it in time, do not panic - the dolls and idol will despawn, but you can replace them and try again.
