Those that Skitter
Eight Day of the Third Month 294 AC
Time warps and halts at your command. The tanar'ri are not dying a True Death, the world is not so kind as to grant you that, but they are being consumed for there are evils in the heart of the Abyss older than the sins of men that gestate into Daemonkind, parasites of the soul reduced from mighty tyrants of yore. Nameless they are to all but the most depraved or the most ambitious of conjurers, forgotten almost even by the dream for the revulsion of their being, but of the tomes Lya has read they are not misplaced...
Qlippoth.
"They are
parasites," Lya proclaims, barely above a whisper. "We did not call them but they were already feeding on the demons. They ate it from the inside the moment it became stone, unable to defend itself." Here yet not, feasting at the bleeding edge of realities between the spheres. It is your own demiplane that allowed them to remain unseen by the sharp eyes of Erinyes and watcher-creatures. You almost wished they stayed that way, after speaking the wish as Lya asked you to.
A
Thognorok is a uniquely hideous thing even besides all the ugliness you have ever witnessed, twitching like a spider, pulsing like cancerous flesh, always hungry, always feeding.
One of the mages dry heaves as he averts his eyes. You cannot blame him, even the brief glimpse of the thing before it was sealed in a vial was enough to make you wonder if the Abyss touched some deep wound to Madness deeper still.
"How many demons have we summoned so far?" you ask his slightly more strong stomached companion.
"Eight hundred and twelve... er, eleven now, Your Grace," the sorceress replies.
"One in eight hundred is not statistically relevant," Lya notes clinically, "But we are going to need a way to pull them fully into the demiplane to deal with them that isn't wishcraft. I'd like to study the ability, but..."
"This is not the time," you finish, firmly. It might not even be relevant outside a demiplane. The concept of forming a pseudo-ethereal realm is admittedly fascinating, but the thought of dealing with and entirely new sort of foe, one that feeds on demons is not pleasant.

"Have you considered simply leaving the statues in the acid a few moments more, my lord?" Mereth interjects.
"I doubt such creatures as would parazitize a lesser tanar'ri have the wit to wait to devour the whole of their host until they are out of immediate danger."
Specifically calling another infected demon takes much of the rest of the day's study and reading from Lya, but once you manage it Mereth's words prove true. All you have to do is not pull the petrified demons from the ooze instantly and their passengers will destroy themselves in the moment of their gruesome feast.
What next?

OOC: And here we go, I got some low rolls for summoning and thought, 'this is the chance to introduce some more about how the Abyss works' as well as the way artificial planes imitate real ones. The idea was to have more fresh research projects for next month. Looking back @Azel and @Crake are right I definitely could have introduced it better. Not yet edited
