廃棄孔 is one of those kanji Nasu uses as a term for many seemingly unrelated things and drives JP theorists (mainly Drill) insane trying to find the connections, so I've been recapping its usage cases. I think these are all instances in chronological order.

1st, December 2016, Goetia's wastehole, marked by the Fuyuki icon, described as a function that Goetia didn't want to have but was necessary. Its demons are Murmur, Gremory, Ose, Amy, Belial, Decarabia, Seere, and Dantalion, under the leadership of Andromalius. Dantès is the leader of the Servant squad fighting this, for whatever its worth.

2nd, January 2017, Dantès 1st interlude, it's revealed that after Prison Tower, Dantès's malignant information vestiges went to Fujimaru's wastehole, where he's until this day fighting "vengefulness" (malignant information from the other enemies that reach Fujimaru's wastehole after defeat).

3rd, January 2018, Last Encore starts with all the malignant information of all dead losers piling up in the wastehole and forming Hackuno.

4th, May 2018, Beast Kiara's profile says that she saves mankind by being the wastehole where they deposit all the malignant information that would be inconvenient in their attempts to do good deeds.

5th, February 2019, SE.RA.PH rerun has a side story set on a wastehole used to deposit Kingprotea.

6th, November 2022, Dantès 2nd Interlude, Chaldea's summoned Dantès finds out that the situation of Fujimaru's wastehole is getting beyond what the Dantès in there can handle, so summoned Dantès and Fujimaru visit the wastehole and help Prison Tower Dantès beat malignant information of Ibuki and Cernunnos to lighten his load.

Potential copes from there:
- The common trend in all uses of the term is that the wastehole is always associated with malignant information, and malignant information is a potential indicator of TATARI/Night of Wallachia (on my way to put Zepia in my main story bingo card and fail for the 5th time in a row, and I swear I'll never learn this lesson).
- Last Encore's wastehole is also named Rose Garden of Limbo, and Limbo is an avatar of Douman's malignant information.
- Fujimaru’s wastehole is more than Dantès can handle, so we get an overflow of vengefulness from past enemies, which will demand a thorough clean-up, allowing Lasengle to get away with not designing any new enemies. Wave with 3 Cernunnoses.
- Oblivion Correction -> Inability to forget -> Memory as magecraft -> more Cerejeira content.
- Since OC1 is in a creation of Sion and OC2 is inside Fujimaru's mind, OC3 and 4 will be set in non-physical spaces reflective of Kadoc and Goredolf, in any order. And the Shielder mini-episode will be that for Mash.

More reasonable assumptions to make:
- A tie between the Oblivion Correction of the Avenger Class and the Oblivion Recording speech about how forgetting is a mechanic meant to dispose of the malignant information that would hinder continued survival. Avengers are important because they can deal with situations that people who prioritize survival can't.
