The auditors have freedom in setting their agenda. Any thread they start outside the Residency and the Frigate can have the Event status, which means they may bring opportunities to secure Legitimate Suspicion, Conclusive Evidence, or otherwise gain some Game Momentum. The requirement is there are at least two player characters (supporting characters of the same player don't count) and Sardaukar presence in the thread is resolved (either accepted, or overcome with Communicate 3).
By the end of Day 1 they may already have got ideas about who are the stakeholders on Arrakis, even if the picture is not complete.
- The Streets, The Sook or the Spaceport are places where they can seek interaction with the already met NPCs or seek new contacts. Transit back to the Spaceport can be arranged at the courtesy of Count Fenring, on one of his thopters, if needed.
- The Outskirts is the right place if they want to investigate the aftermath of the explosion, manufacturing facilities, storehouses etc. Groundcar or Thopter is needed to get there.
- The wider Imperial Basin is the area they can commit to a wider patrol within their allowed scope, perhaps finding a place worthy of investigating along the inner rim of the Shield Wall. A thopter is needed throughout.
By the end of Day 2 a vote will have concluded whether to stay put in Arrakeen for another day or to move the Frigate to another region.
