* AlliterativeName: Milo Morai
* AThreesomeIsHot: Several characters have more than one wife at a time. Not so much the other way.
* AuthorAppeal: Addams liked Armenians enough to write them into the book.
* BigfootSasquatchAndYeti: The Kleesahk
* BlessedWithSuck: While being Undying has lots of good things about it---immortality, for one---it does have drawbacks. Like sterility. And being very prone to amnesia after a few centuries; brain damage ''will'' heal, but memories might not.
* BlindSeer: Blind Hari Krooger.
* BrotherSisterIncest: One of the pairs of Undying.
* TheChosenOne: Milo Morai not only wrote the prophecies, he made sure to choose himself to fill it.
* CombatByChampion: Featured in the first book between Lord Alexandros Pahpahs and Lord Demetrios.
* CoolHorse: They are called the Horseclans.
* CorruptChurch: Several of these---Adams did ''not like'' churches, it seems.
* DepravedBisexual: Quite a few of the Ehleen nobles.
* DepravedHomosexual: The ''rest'' of the Ehleen nobles. Nearly every single Ehleen noble has a passion for gay rape.
* EternalEnglish: Averted, though mostly shown in names.
* TheFogOfAges: After a few centuries, the Undying in many cases forget their past.
* GentlemenRankers: In ''A Man Called Milo Morai'', Sergeant Jethro Stiles identifies himself and Milo as these. Stiles considers himself to be doing penance for an unspecified moral failing which happened in his past.
* {{Ghostapo}}: Hitler was one of the Undying, with incredible psychic powers.
* GrandTheftMe: The [[spoiler: Witchmen]] do this quite a bit---with mechanical assistance at first, but later on, at will.
* HiddenElfVillage: Milo Morai spends a couple of centuries looking for one of these.
* HornAttack: The Shaggy-Bull is the product of an attempt to recreate Bison primogenus, the prehistoric longhorn bison. It has long, sharp horns that can inflict lethal damage on its opponents.
* HumansArePsychicInTheFuture: Also the cats, horses, and whales.
* KnightInShiningArmor: Geros Lahvoheetos is polite, humble to a fault, unfailingly chivalrous and courageous. Has trouble grasping that wetting himself in terror would only be cowardice if it ''stopped'' him from behaving bravely, which it never does.
* MagicalNegro: The Zartogahn characters are almost always doctors.
* ManlyTears: The fierce warriors of the Horseclans freely express their emotions among those of their own kind.

* PoliticalOvercorrectness: ...could basically be renamed "Ohrgahnikahnsehrvaishuhn"(Organic Conservation), the religion of the "Ganiks", descendants of hippie communes.
-->“Take all of the detested and heinous abominations of conduct despised and almost universally prohibited by races or communities of civilized man, and you had the mundane, everyday practices of your average, run-of-the-mill Ganik...” (Bili The Axe)
** "Kahlodjee"(Ecology) forbids taking anything out of the ground except for use as food. So they don't mine or forge metal. However, they'll gladly claim metal tools and weapons forged by someone ''else'' - after slaughtering them for doing it.
** "Kahnzuhvaishuhn"(Conservation) forbids wasting anything, so they wear clothing until it rots.
** "Ndaindjuhd"(Endangered) forbids consuming the flesh of any animal. Veggies only... with non-animal meat on the side. Specifically, [[ImAHumanitarian humans]], even their own dead. Conquered enemies are at the top of the menu.
** "Pozahjizm"(Pacifisim) is only practiced by Ganik slave-farmers. To engage in combat, even in self-defense, is punished by on-the-spot execution.
** "N’Vymhndt"(Environment) and "Plooshuhn"(Pollution) forbids poisoning the air, land, or waters. So they don't burn anything, and they never ''[[TheDungAges bathe]]''.
* RapeAsDrama: Lots and lots of it, of both genders; but it's only presented as wrong when the bad guys do it.
* ReallySevenHundredYearsOld: All of the Undying eventually, but in particular Milo Morai and Clarence Bookman.
* SelfFulfillingProphecy: Milo Morai wrote his own prophecies.
* TheWomenAreSafeWithUs: Averted, captured women are given as slaves. Not Children though.
* WarriorPrince: Bili Morghun, aka Bili the Axe. Born heir to a duchy but rises to archduke and later prince of his part of the Confederation. A pleasant gentleman to those he finds honourable... but also a very deadly warrior and prone to sometimes brutal judgement, such as massacring rebels by the hundreds to ensure that the consequences of rebellion will be utterly apparent for the future.
