Upon first entering the Market District, a notice will appear on the screen reading "New Topic: Do you need couriers?". However, this topic cannot be discussed with any NPCs. This may be a leftover from a scrapped quest or questline in which the player would deliver letters to NPCs. The string of text's file name is "ImpExWork", with "ImpExDeliveredLetter" and "ImpExGiveLetter" also existing in the game's files.
