Oh.
That makes sense.
The Project just has to find another Lawful Evil cleric of Irori to take over Carissa Sevar's job. Who says she was special? Maybe it was just that Lawful Evil priests of Irori are rare in Cheliax, and really any of those will do, for that part of the Project. Maybe you can get a better Irorian if they're of high circle.
There's something almost crushingly sad about the thought. Pilar sets it aside.
And then the other penny drops.
Lawful Evil Irori cleric in Egorian. Pilar hasn't met them but she knows who that is.
"Sajvara."
