The Mnemonic Mystery Mollified Momentarily

The townsfolk of New Hallow are a gregarious lot, normally. We were all, in some small way looking forward to returning to the little hamlet we'd called home for these recent months, so it was a bitter susprise when we encountered trains of refugees fleeing from the town outside the nearby village of Wildholde. In addittion to recent raids and skirmishes with the feyfolk and our old adversary <insert Dryad's name here> the townsfolk seemed beleaguered by an endemic amnesia. Many familiar faces looked upon our trio as if we were strangers, never encountered before.
 
Investigating this phenomena, we found ourselves knocking on the door of the local church of <insert Deity name here> in Wildeholde, a partially walled town bigger than New Hallow but no metropolis to be sure. The new priest there had been aiding our former neighbors with food and drink and solace, we learned. So we set off to "thank" him. He was cagey and dismissive, so we returned later with a little churchwarming gift. First we scouted the premises, detecting troublesome emanations of evil forces. So we decided the best thing we could do for him was throw him a surprise party and make sure we rid the church of any desecration, like undead or evil.
 
He seemed less than grateful, so we offered to do some remodeling, deciding we might need to burn the place to the studs. With some well placed demolition charges from Gugs, some percussive bodily maintenance by Elvar and some quick remodeling (I put in a "conversation" pit in his basement den) by yours truly, we managed to make him more pliant and cooperative. Unfortunately we may have broken him in the process. Time will tell what our next moves are.
 
First to find out if we've frogmarched the forgetfulness, ambulated the amnesia and freed the foggybrains of our fellow townsfolk and then perhaps to return to New Hallow to wreak our vengeance against the overstepping Fey.
