** The [[spoiler: Qax]]'s BigDamnVillains moment, where they [[ColonyDrop toss a star]] at the photino birds and unleash their Spline fleet in a "baryonic blitzkrieg".
** In ''Ring'', Spinner-of-Rope and Michael Poole fly the ''Great Northern'' [[spoiler: back in time]] by looping around a cosmic string.
** [[GuileHero Jim Bolder]] tricks the Qax into [[spoiler: blowing up their own sun]].
** Humanity's war against the Xeelee was stupid and pointless, but [[spoiler: their victory at the end of ''Exultant'']] nonetheless qualifies, if only because [[spoiler: forcing the Xeelee to vacate the Milky Way]] gives humanity a chance to progress and recover (and we do learn from ''Transcendent'' that things do indeed get better...[[CrapsackWorld for a while]]).
** Even if [[spoiler: it didn't work out and they went back to banging their heads against the Xeelee wall]], humanity reached the point of near [[AscendToAHigherPlaneOfExistence ascension to godhood]] in ''Transcendent''. Not bad for a bunch of [[PunyEarthlings apes]].
* RetCon: There's some inconsistencies across the series, mainly between the earlier novels and the ''Destiny's Children'' books. Some of it is simply the result of a lot more light being shed on the period between the fall of the Qax and the end of ''Ring'', but (for example) the fact that Xeelee-style FTL drives [[spoiler: function as time machines, including the ability to create paradoxes]] is only revealed in ''Exultant'', when one would have expected it to be mentioned earlier.
* TearJerker: The end of ''Mayflower II'', one of the stories in ''Resplendent''. The immortal protagonist, guardian of the titular generation ship, has lost everyone dear to him, watched the onboard society unravel and then the inhabitants devolve over generations. [[spoiler: Then two of the main characters of ''Exultant'' (who are now married with a baby) show up to rescue the pitiful descendants of the original crew and tell the protagonist he's done his job well. Finally able to rest, he sees the face of the lover he left behind before the voyage. It's left ambiguous whether it's a hologram the visitors left for him or just a hallucination, because it doesn't matter.]]
