YMMV: Black Legion
- Come for the X, Stay for the Y: Come to see the beginnings of been-there-since-forever faction, stay for surprisingly deep and engaging characters.
- Fridge Brilliance: There's a lot of symbolism to the scene where Khayon hurtles Tlaloc at the Canticle City. It's the last thing that truly connected him to his Prosperan past, thus by doing what he did he casts aside his Thousand Sons' legacy in favor of the Black Legion. Second, considering the above, the amount of effort he puts in hauling it behind him is a good metaphor for how he had to work hard to free himself of his past. And third, the relief he feels at being rid of it is... well, the relief he feels at being rid of more metaphysical "it".
- Heartwarming Moments:
I've done you an... injustice. It's time to rectify it.
- The scene where Khayon walks, flanked by Telemachius and Lheor, like he usually does with Djedhor and Mekhari. He's quite surprised to feel their thoughts and hear their breaths over the vox. When Lheor asks what is it and hears "It's just... you're alive", Khayon expects mockery. Instead, the World Eater just nods in understanding, cementing the brotherhood between the two.
- The scene where Telemachius tells Anamnesis the legend of Nayadas. It's the first time we see him as more than just hedonist pleasure-seeker and realize that he desperately craves something more in his life, just like the others. Khayon sees it, too, and frees Telemachius right after this scene.
- Rescued from the Scrappy Heap: Abaddon. He suffers from at least two memes that make him a complete loser, one because of his thirteen attempts to launch Black Crusades (and since it was barely explained what they were, most assumed he failed all) and the other claiming he has no arms.note With this book, many start seeing in a better light.
