Lady Argus is mostly preoccupied with her own inquiries, but she does purchase a small team of horses and a wagon for use on inquiries that require travel to other cities. You get the impression that she's interested in taking on more jobs in nearby cities, but not in expanding operations fully there just yet. For the most part, she leaves the day-to-day operation of the business to you, though.
Thus it's nothing out of the ordinary when a jittery Free-Cities Elf comes calling one morning while you all happen to be in the headquarters.
