You’ll know your nearing your objective when you’ll be attacked by a group of Guards and their commander. Talk to Clarissa and learn that Tolman has been captured by Piety and taken to the Crematorium.
Locate the waypoint within Sarn Slums and enter the nearby Crematorium.
Proceed to the level 2 and at the very end you’ll meet with Piety and her remaining guard escort.
(Note that Piety deliver quite a nasty jolt with her lightning abilities and that you should probably get some resistance accordingly before you fight her on your first playthrough).

Once you have acquired all 3 Busts return to Sarn and speak to Hargan to receive 2 free respec points as well as 1 passive skill point.
The Gemmling Queen
This quest dialog is available to you from Gridor upon completion of the preceding quest Lost In Love (after you have given the Bracelet to Clarissa) ; It require you to travel to Solaris temple in order to find the Gemmling Queen (also know as Lady Diala).
The entrance of Solaris temple is located in Battlefront ; Since you are required to travel through there to get to your destination, you might as well locate & pickup the Ribbon Spool which will be required from you once you have met with Lady Dialla.
Travel to Solaris temple lvl3 and speak with Lady Dialla (she will always be located right by the waypoint). Give her the Ribbon Spool and receive an unidentified rare ring for your troubles.
Lady Dialla will then proceed to explain to you (at least I assume she does as I could never be bothered to read the entire storyline) that you will need to find a way around the blockade in Battlefront in order to reach the Barracks and killGeneral Gravicius.
To do so, you will first need something to clear your way through the Undying Blockade in the Warehouse sewers.
That something happens to be Infernal Talc made from Sulfite.
Use the waypoint, travel back to Battlefront locate the entrance of The Docks and proceed with acquiring the Sulfite.
Return to Lady Dialla and obtain the Infernal Talc which effectively conclude this quest.
