In a sheepfarmer's low stone house, high in the hills above Three Firs, two swords hang now above the mantelpiece. [...] The other is a very different matter: long and straight, keen-edged, of the finest sword-steel, silvery and glinting blue even in yellow firelight. The pommel's knot design is centered with the deeply graven seal of St. Gird; the cross-hilts are gracefully shaped and chased in gold. [Old Dorthan reminds his grandchildren] of the day a stranger rode up, robed and mantled in white, an old man with thin silver hair, and handed down the box [with a scroll] and the sword, naked as it hangs now. "Keep these," the stranger said, "in memory of your daughter Paksenarrion. She wishes you to have them and has no need of them." And though he accepted water from their well, he would say no more of Paksenarrion, whether she lived or lay buried far away, whether she would return or no. The scroll Dorthan reads is headed The Deed of Paksenarrion Dorthansdotter of Three Firs, and many are the tales of courage and adventure written therein.
Sheepfarmer's Daughter - 18 year old Paksenarrion ("Paks" for short) runs away from home and an unwanted Arranged Marriage to become a warrior. She signs up with the mercenary company of Duke Phelan, undergoes training and fights in her first wars. She comes out relatively well for it but starts to wonder whether she's always going to be fighting for the right reasons and where her allegiances ought to lie.
Divided Allegiance - Paks leaves the mercenaries to enter training as a paladin candidate in the order of Saint Gird. In the process she meets and travels with the other races of the kingdom and also has an encounter with the kingdom's Religion of Evil that does not end well for her, threatening her future and livelihood.
Oath of Gold - Broken from the events at the end of Divided Allegiance, Paks must come to her senses, regain her courage and rediscover her calling to Paladin-hood even without the formal organization of Gird's order. Also, there's the question of a lost king she goes on a quest to find. And the aforesaid Religion of Evil - Achrya the Webmistress and Liart, the god of torment - are still hard at work.
All three books are available in a compiled omnibus edition. Moon would later write a pair of prequel books about Gird himself, Surrender None and Liar's Oath, collectively titled The Legacy Of Gird. A second series of a projected five books, set after The Deed of Paksenarrion and entitled Paladin's Legacy is also in progress. Oath of Fealty, Kings of the North, Echoes of Betrayal (formerly announced as Crisis of Vision) and Limits of Power have already been published.
Oath of Fealty - A continuation with Paks as a background character, showing the effects of Oath of Gold. The lost king of Lyonya has been found, but now he must learn to rule a people and a culture he has never known. The void he left behind him in his old life must now be filled by his loyal deputy, who never expected to command. And the traitorous duke of Tsaia has been slain and his entire family placed under Order of Attainder... except for one expatriate mercenary captain who is now suddenly finding themself the new duke, having to bring peace and order to a domain deeply tainted by Liart. Add in that someone is attempting to shatter the Guild League alliance of the South and, well, the reward for a job well done is another, even harder job.
Kings of the North - Kieri, new King of Lyonya, and Dorrin, new Duke of the traitorous house Verrakai struggle to set their lands in order as a mounting threat to the south rises. Kieri's human advisors and subjects pressure him to marry, while his elven family are strangely distant. The continuing rumblings of an unsettled peace and frightened princess from hostile lands only add to the problems facing the former mercenaries.
Echoes of Betrayal
Limits of Power
The inspiration to write Paks allegedly came from Moon watching people play paladins in Dungeons & Dragons and deciding "such a person wouldn't act like that" - perhaps the players in question were playing their characters as Lawful Stupid, something the book averts tremendously.
Asexuality: Paks just isn't interested, she's even asked at one point if she prefers women (she doesn't), having rejected the advances of men in her cohort, and she maintains her disinterest through the whole story.
Attempted Rape: Almost happens at the hands of resident Jerk Ass Korryn during the early days of Paks' time with the Duke's company. And she is actually raped, repeatedly, when she surrenders herself to the priests of Liart near the end of Oath of Gold in order to buy Kieri time to reach Lyonya.
Averted in that Paks spends at least half the third book arguing with elves, and does so without needing to enter Screw You, Elves! territory. She even analyzes why she can:
Paksenarrion: (thought balloon) Humans need not, Paks saw, worship their immortality, their cool wisdom, their knowledge of the taig, their ability to repattern mortal perceptions. In brief mortal lives humans met challenges no elf could meet, learned strategies no elf could master, chose evil or good more direct and dangerous than elf could perceive. Humans were shaped for conflict, as elves for harmony; each needed the other's balance of wisdom, but must cleave to its own nature. It was easy for an immortal to counsel patience, withdrawal until a danger passed... She took courage, therefore, and felt less the Lady's weight of age and experience. That experience was elven, and not all to her purpose. Kieri Phelan himself was but half-elven; his right to kingship came with his mortal blood. And as she found herself regarding the Lady with less awe, but no less respect, the Lady met her eyes with dawning amazement.
Though Kings of the North dives into "played straight" territory with the Screw You, Elves!: The Lady of Ladysforest refuses to help Kieri co-rule Lyonya as is her duty, tries to prevent one of the Kings Squires (Arian) from marrying Kieri by insulting Arian in front of Arian's father and an assembled court of elves, THEN gets herself trapped underground due to her rude behavior to the gnomes and tries to blame it on Arian. Kieri, Dorrin Verrakai, Arian and a dragon all call the Lady out on this, Dorrin especially: "High rank never excuses wrong behavior".
The Lady of the Ladysforest, the High Queen of the elven race, later confirms the accuracy of these observations.
The Lady: We singers of the world, who shrink from disharmony, may choose silence instead of noise, and not always rightly.
Cold-Blooded Torture: A hobby of the priests of Liart, at at the root of at least one Crowning Moment for Paks.
Church Militant: Most religious orders of the world have a branch of these.
Crystal Dragon Jesus: Averted with the High Lord, a nigh-universally acknowledged god whose celebrations tend to be folk festivals. It's the minor gods and their churches that collectively function as Crystal Dragon Jesus, such as St. Gird.
Demoted to Extra: The "Paladin's Legacy" series is about the aftermath of Paks' deeds in the third book, and focuses mainly on Kieri and Dorrin. Paks herself is relegated to recurring minor character. "Liar's Oath" relegates Gird to one (Who dies halfway through); the book is about Luap.
Everyone Calls Him Barkeep: Luap is a term that refers to someone with rank but no real authority. The man known as Luap to the followers of Gird was referred to as "Gird's Luap" or just "the Luap" so frequently even in his own time that few people remembered that his real name was Selamis. By Paks' time his real name was completely forgotten.
A Father to His Men: Duke Phelan. Certainly some of the other mercenary dukes as well, but Phelan takes a fatherly interest in Paks' development above and beyond the call of duty, even after she leaves his company.
At least partly because Paks is roughly the same age as his daughter would have been.
Fantasy Pantheon: The High Lord and his saints, a bevy of regional gods and goddesses.
Insignia Rip-Off Ritual: A non literal example. To be turned out tinisi turin is the worst punishment short of death for a mercenary soldier turned out of the force under disgrace: publicly stripped, a full-body shave, beaten, branded then expelled.
Specifically, tinisi turin is being shaved completely; it means to be short like a sheep, and is a common humiliating punishment. The flogging, branding, and expulsion are separate and (obviously) more serious.
Patronymic: This seems to be the practice in Paks' hometown at the very least. Her last name is Dorthansdotter, and her father is Dorthan Kanasson. Quite a few other people, mostly from the north, also have patronymics.
Sdrawkcab Name: Apparently, in elvish, reversing the spelling of a name inverts its meaning — hence the elves (sinyi, singers) are opposed by their evil kin the iynis (unsingers), and the gods Adyan the Namer and Sertig the Maker have their counterparts Nayda the Unnamer and Gitres the Unmaker.
Also, Gird is what happens to St. Cuthbert when you do a Jerkassectomy.
The village of Brewersbridge and the ruin from Divided Allegiance is taken right from AD&D module T1: The Village of Hommlet: the town, the druid, the ruin with the bandits and the rest.
Skeptic No Longer: Paks transitions into this: in Sheepfarmer's Daughter she starts off not knowing about Gird and doubts the over-zealous Effa's professions about him (particularly after Effa dies). Then it becomes evident that the gods have an interest in protecting her and as she learns more about Gird she starts coming around.
Effa is an obnoxious evangelist. Paks has more issue with the problem of evil: why don't the benevolent gods protect good people? At least in a setting with evil gods as well there's some justification, but the High Marshal largely shrugs and says nobody knows why the gods seem to act through clerics instead of directly. She does have more solid theological material, too.
She goes on a skeptic journey. First she's dubious about the idea of worshipping saints. Then she warms up to Gird and joins the Fellowship. Then she leaves, and swears fealty to multiple gods, eventually telling the Marshal-General that she's no longer under the command of the Fellowship or Girdish, exactly
Truce Zone: Valdaire, the truce city where the mercenaries stay the winter and train.
Uncoffee: Sib, a warming and revitalizing beverage. It's bags of bitter herbs steeped in hot water, often mixed with honey — a lot like tea — except that tea also exists in this universe, and sib is different.
There is another beverage named "asar", which may be a candidate for this trope, but we are never given any insight into the properties of asar beyond it being hot and having restorative properties attributed to it.
White Magic / Black Magic: Powers granted by good and evil gods/saints to their paladins, marshals, priests, clerics, etc. There are wizards with a different, neutral form of Functional Magic that is never fully expanded on in the main trilogy though elements of Rule Magic are hinted at. Magery is a hereditary power associated with the old mostly-evil aristocracy and the god of torture, and is banned in all civilized lands.
