And Irabeth has a briefing.
The current plan is to split up into two groups: a larger group, led by Irabeth, which will be distracting the demonic forces and making it possible for the second group to reach the Wardstone at all, and a smaller group, led by Select Artigas, which will be attempting to reach and purify the Wardstone. (Select Artigas's party will also be accompanied by a few, ah, local experts on disabling traps, and two members of the Order of the Flaming Lance.) Most likely Blai's team will still have to face some demons, but hopefully the larger team can reduce their number and (critically) distract Minagho. Communication between teams will be handled by having familiars carry physical notes, and therefore will be extremely limited, unless someone manages to scrounge up a better one.
They have information about the following secret passage, which they intend to use to enter the Gray Garrison. They have a separate informant who verified various information under Abadar's Truthtelling about the composition of the demonic forces and their layout. Highlights include: there is at least one succubus. This part of the Garrison has been taken over by brimoraks. These parts of the Garrison have particularly deadly traps. Vrocks have periodically been teleporting in and out, though as of a few days ago there were none permanently stationed in the Gray Garrison.
Select Artigas and Luminary Ingaberta should speak to her after the meeting for more information on spell allocations for their contacts. They will initially be gathering at a few different staging locations, which will enable them to more efficiently distribute long-duration buffs from the noncombatants and avoid interpersonal tensions. (Blai may pick up on the fact that 'avoid interpersonal tensions' is in part a euphemism for 'avoid the Desnans being arrested by Hulrun'; she has arranged the staging groups so as to avoid this permitting them to simply break Thall out.)
Many of them will probably die. But they will die in service of not letting demons overrun all of Golarion.
Any questions?
