The Allurists Guild informs you that business near Torment and 16th has been slow lately. Persuade 6 prestigious vampires (with at least 500 blood) to visit Baker's Tavern there and tell the bartender "Zachy sent me". You have ten days. You must not set foot inside the pub yourself during the quest - drunks give us a bad name.
This is for my charisma 2 quest, it'd be great it you could stop in there and tell them this.
