In the initial dialogue for this quest, Rother Nerevyn asks me to talk to Porcilla Dythos, who is the chief clerk of the "Census and Excise Office". In fact, this office does not appear to officially exist, although there is an Imperial Census Office near Ebon Tower, and a Customs Office near the gate. Perhaps it would be less confusing if RN indicated that PD was in the Harbor Ofiices next door?
