-[X] Psychic ability is a pathway to many things one would consider unwise, and this action is certainly among those. Curse our dear interrogator with flashes of divinatory revelation, glimpses of the alternate world where some past choice had ended up with her, here, among the cult's members. What would do? What would she think? What would she look like? What would she feel? Visions, so tempting that you need to keep watching, to find who's doing this to you, and perhaps join them
-[X] Arrange for the interrogator to be socially isolated before the operation. The great houses of Thedas probably won't like someone sniffing around in their affairs, so it shouldn't be hard to suggest them that thankful for the intervention they are, they don't want to take her obviously precious time with their social events. For all her training, she's still human, and when humans are isolated, they will be more open for... new connections. Especially new connections that listen, empathize and understand how hard it is to fight a lonely war against the dark for the sake of people who will either never know of your contributions or even resent them.
-[X] The interrogator expects the cult to lose cohesion, which on the ground would mean losing assets, protection contracts, shady deals. Rival gangs moving in. And wouldn't you know it, you just got a friendly rival gang.
--[X] As part of the feign create small skirmish against Skavz and mock skirmish of us vs Orbtz to really sell the Orbtz are the controller of the territory.
