Received from: Sol Pan [New Ashos] (M23:40)
You will receive this task from Sol Pan only after completing [Dead Lover]. The woman is at her place.
The woman will ask you to deal with ghosts of some of her former lovers. Each one she has touched ended up killed by Dir Tal guards. You have to complete a series of three quests and get rid of the ghosts of all her former lovers' ghosts.
To continue, you have to complete: [Atypical Girlfriend], [Horny Quartet], [Unmet Need].
After dealing with all of them, return to Sol Pal (M23:40) and tell her that the ghosts are gone forever. You will receive Sol Pan's pendant.
You will receive this task after accepting [Betrayal].
Firstly head to the market, where you will find the ghost of Li Lith (M23:20). After a very short conversation - irrespectively of how you lead it - the ghost will disappear.
You will unlock [Horny Quartet].
