Helnim, Aarlen Lleranoth's Basement feels too cramped for two people IMO, and it's almost impossible to access half the area just because of NPCs. If it is possible I'd suggest scrapping the gambling idea and put something more traversable over there. Firewatch IL needs the gamblers. Still, if possible some adjustments would be nice to improve traversal.
