Barnabus:
Are the three cultists still visible?
Yes, all three are quite visible. All with their hands raised in surrender. As an additional point, the fumes do not appear to have had any negative impact on the cultists or anyone else in the room (I.e. there is no indication that they are poisonous).
Barnabus:
Some time ago, this temple to Impurax was sacked and ruined by the local do-gooders.
Was that the only structural damage caused by the assault?
There was no structural damage caused by the assault. The collapse of the roof is the ultimate result of elemental erosion and neglect.
The assault carried out by soldiers of the Duchy essentially consisted of a group of men-at-arms entering, killing everything that moves, and closing the joint up, followed by stern warnings to the local populace that the temple was haunted/evil/a bad place to have a picnic.
As a further bit of understanding, despite the soldiers’ readiness to wipe out Impurax’ clergy, they still regarded them and the temple with genuine fear. Once the proverbial deed was done, no time was wasted in leaving.
Barnabus:
Not even a minute ago as the kids say, the temple was repurposed for Nergal and his religious order. This event occurred after we discovered the Nergal shrine.
Was the structure of the temple restored during this event?
To reiterate, the structure wasn’t damaged in any deliberate way. The soldiers which comprised the forces of the Duchy in that period didn’t have access to any kind of siege equipment. I don’t believe that razing the temple itself was ever seen as a realistic goal. So instead, those who occupied the temple were put to the sword. Think Salem.
So, the cultists of Nergal haven’t restored or rebuilt anything. They’ve just moved in. In fact, as you have likely already discerned, there are portions of the temple they’ve basically left unaltered.
This alludes to a point worth considering. The map which Mazzahs borrowed from
The Foul Pheasant’s proprietor seemed primarily concerned with the temple’s underground level. Given what Dax observed at the only exterior entrance to the basement,
something unpleasant has transpired down there.
Barnabus:
Less then a few minutes ago, we discovered the still extant journal of a high priest of Impurax, evidence of his death still visible (blood/cracked desk).
I don't think the paladins would have left his journal behind but whisked his body away.
Although the wrecking of the temple doubtlessly occurred with the Chuch of St. Ygg’s tacit approval, paladins were not directly involved in sending the fun loving clergy of Impurax to their graves. The soldiers who carried the attack out, in the main, were regular men-at-arms in the service of the Duchy’s leadership. Most of those soldiers (rightfully, one might argue) viewed the temple with fear and superstition, and didn’t want either to linger on the premises or take any of the accursed items within the place out where they could cause further harm. At the time, stern warnings from the soldiery and terror about the place being haunted were sufficient to leave it undisturbed.
Sure, one could argue that some intrepid evildoer who was interested in the secrets of Impurax could break in and find some cool stuff. On the flip side, the authorities had sent a rather strong message about how the worship of Impurax was viewed in the region. The latter seems to have held. I mean, after
that, who’s going to be crazy enough to turn up in Helix and announce that they’re a follower of Impurax?
(For the record,
most of the knights of St. Ygg at the time were focusing their efforts on the region’s greater evil, the Barrowmaze. See also: Sir Guy and his companions seeking to close the pit within the catacombs. The followers of Impurax were bad, but they were second stringers compared to what was wandering out of the tombs.)
Barnabus:
Did the restoration of the temple return it to a previous point in time -- just prior to its destruction?
The temple was never demolished. Just abandoned. The soldiers who performed the raid boarded it up and warned away the curious. In the years since there has been the occasional story about some questioning soul who wandered into the place and was never seen again. The ruins have been shunned. Even the merchants established a new route which avoided the haunted site.
