The Allurists Guild informs you that business near Yak and 90th has been slow lately. Persuade 8 prestigious vampires (with at least 500 blood) to visit Falconer's Tavern there and tell the bartender "Sonnet sent me". You have ten days. You must not set foot inside the pub yourself during the quest - drunks give us a bad name.
Last one. I promise.
