Not this campaign we got a direct landline to at least three level 20 NPCs

Yeah, its a bit of a problem. At least with Morri and Hexxum (Fearne and Ashton respectively) it is very clear that should they ask for help in this issue, it would cost them immensely. The debt accrued for bringing someone back from the dead with either of these people would be insane. And as for any contact that Esteross can find? Well, given his situation, there is far more uncertainty; especially in terms of timetable. Even though that is an avenue they "earned" through choices in the story.

The issue really is Orym's direct connection with Keyleth, and by extension VM. Because Liam built this into his backstory, this draw for people to want to "push the VM button" at any given hardship the group faces would be very tempting. And we see that exact factor after this episode. Keyleth would never ask a price for them beyond maybe the material costs; there are no strings attached. Unless Matt has her stand firm on "Reincarnate" as her solution to their problem I suppose? I dunno?

Maybe, if they do call her, once she's done the deed ... Matt will attack her again and remove her from the board for at least the next month. Its very clear the powers at play want her at least indisposed.
