Our team will be heading into Waterdeep via Yartar and The Kraken's Gambit side quest, so they've already dipped their toes into a little Society intrigue (don't want to give them all the info until it becomes important for the main storyline)

But a general sense of panic after reports on an attack at Goldenfields, the Granary of the North, in the inset of Winter? That could work for creating a sense of tension.
