Taken from one of Yssith-Atil’s note books:
On the way back to Boggard territory, Varia spotted the aboleth in its hideout. We made a mental note of that location and moved on. Nearing the boggard’s land, we saw that the swamp was covered in crows. The boggards were as successful in fighting the plague as the humans. We put Issilar and Het-Kiril in a boggard house and boarded it up, then headed toward the troglodyte lands. The only boggard survivors that we found were already infected and dying on an island between the boggard and troglodyte lands
When we arrived at the troglodyte area, veiled as troglodytes, the locals were weary of any strangers who might have the plague and tried to herd us away. We ducked into an alley and cast a locating spell which found the mantis sword in the local ziggurat. We then left the area because the locals had started to gather around us, calling out our location to each other.
Since the sword was a secondary priority, we went back to the entrance to the underground river in the boggard area. All of the piranha’s and ogre piranhas were dead, along with a handful of degenerates. Someone had obviously already claimed the gem and anything else in the area. Hopefully the “someone” was one of our few allies.
We went back the troglodyte area and attracted the attention of a giant parrot called a camulatz. We set up some images for it to play with and then we dimension doored into the temple. We appeared in a room with 3 troglodytes and 2 dinosaurs. One of the troglodytes was dressed in some sort of ceremonial armour made of mantis carapace. Varia convinced them that we were pilgrims looking for “the sword” and he offered to administer the Trial of Achaekek. We accepted and he pulled the sword out of a wall and handed it to Varia… if only all the locals were so helpful. We dimension door-ed straight back to the camulatz. The camulatz was a little murderous when we returned, but Varia convinced it that we would try to find it a mate (it bargained to 2, one being a manticore) and it let us go.
We returned to Yog’oltha’s (the aboleth) hideout and tried to find out what this situation was about and who wanted to capture him. By his account, he and the intellect devourer that sent us to capture him are old enemies who both want control of the city. The intellect devourer can also, after he’s killed someone, fill a people’s head with some kind of goo that allows him to control them. Either way, we decided that we didn’t care about this power struggle, and all we really need is the portal gem. So, we knocked him out (after some unpleasantness with slime) and dragged him to the intellect devourer fully expecting to be double crossed. We handed over Yog’oltha to one of the intellect devourer’s minions and the minion handed us the portal gem… just like that… a lot of helpful locals today.
