WHO: everyone who signed up for "BRING IN NATASHA BEFORE SHE KILLS EVERYONE"
WHAT: ...bringing in Natasha before she kills everyone?
WHEN: let's safely call it 22nd through the end of the month
WHERE: Orlais! Then traveling back to Skyhold.
There is trouble in Orlais. People are going missing, turning up dead, slamming doors in the faces of Inquisition representatives. Which would be annoying enough, but reports and information are being delayed, altered, or going missing altogether. People they do make deals with either don't honour them or vanish. The Inquisition doesn't know why.
So Leliana puts together her recon team and heads to Orlais to find out what's going on. As a group, they approach the Comte Valnoir, who withdrew his promise of armour and raw ore in support of the Inquisition, eager to find out why. After a little bit of Leliana's personal brand of charm, he tells them what's really going on. They're informed that anyone who's even considered agreeing to the Inquisition's requests has been warned off. If they don't comply, they meet with serious misfortune, and now no one is willing to risk it. A deal is struck. Eliminate this unknown threat, and negotiations can proceed again in earnest.
Seems like a pretty fair deal. So, Leliana splits her group into smaller teams, sending them to cover different areas of the city, looking for any information that might lead them to this saboteur. Everyone is to stay in contact using the sending crystals - share information and keep the rest of the team apprised of their wellbeing.
One group is staying behind, working from the lists of those nobles who have backed out of deals with the Inquisition. While the masters of the houses may not be willing to talk, servants and house guests usually know just as much and are more willing to talk. Usually. Not always. It's difficult to bribe those who don't need money. It's difficult to threaten those who already don't feel safe. A finer touch is needed here. Which is why she leaves
Obi-Wan, Rey, and Bruce to the task.
Leliana sends a second group to check the shops, inns, restaurants, and taverns in the nicer section of town, a place where a good name and a little bit of implied danger can go a long way. A Warden and a fierce looking elf and an unknown mage. Why risk it? Just spill the beans.
Bethany, Amélie, and Merrick have such trustworthy faces.
She takes the last group herself and heads to a much more dangerous area, the kind of place where the implication of danger isn't enough - someone has to bleed. The same questions will be asked, though not in the same way. The area of town where a tall dark Qunari and a demonic looking "child" flanking the Inquisition's Spymaster will be able to get answers with the proper application of gold and steel.
Leliana knows how to get what she wants,
The Outsider knows how to be creepy as all get out, and
Yael knows how to be huge and imposing.
