The Succubus Quest

Hello All ,
Am not Banned but this is the only place i found to submit a ticket ,
now to the matter in hand , i leveled my warlock thinking at first that i can get pet through my trainer turns out that i can get my summons from chain of quests , so i started the warlock quests i got the void walker now supposedly i get the succubus quest line but i got none , i followed every tutorial and every YT video and i asked a million warlock on the server for help but nothing seems to work so am asking what 's the complete chain of quests and if you can check if am eligible for the quest or not ! am literally lost i appreciate the help and thanks in advance.
Yours, Roxdxebec
