[Hypothetical list of titles for the series. OTOH I'm not sure I've come up with 17 books' worth of material, even in principle. I.e. the demiplane of Apollyon is book 1, 2 through 4 are the Precentor trilogy, 5 through 7 are the Septatheon trilogy, 8 through 10 are the Keyscape trilogy, 10 and 11 are the evil schoolteacher duology, the Dirge-shadow known as the Void of Threnody storyline is somewhere in the next set [IDK if I've mentioned the Dirge-shadows yet here?], as well as the conclusion to Bassilfastion's quest and the buildup to the awakening of Apollyon (that latter is at the end of 16).]

"For the Sake of Three Things": the unholy trinity of the final offenses. Three interlocking (perichoretic) sins, whose personification is the so-called Form of Evil.

"The evil of corruption is negating the essence of goodness in something; the evil of destruction is negating the existence of goodness as something." "But it is possible to think of destroying the properties that make something good without replacing them with other properties that would be evil; the evil is all in the destruction of the good properties, not their replacement or lack thereof. So would not Apollyon be the actual Form of Evil?"
