Fig (Anna Castiglioni) and Whig (Incoherencel) are two patrons that are available via the Robber’s Refuge tavern. Simply talk to Ortheim about altering the drink menu, then get the approval of Evette San in Solitude. This will add the more “posh” patrons, just as Black Briar Mead will bring in the adventurers.
In the video, I’ve done a lot of the requirements for adding new folks, so the tavern is bustling with activity. By altering everyone’s schedules, I also think I can keep adding more people without overloading the area. Right now most patrons are there 3 days a week, but that can easily be altered to 1 or 2, with the weekends being the busiest.
