A prince does not necessarily mean son of a monarch even in human society. Some of the Holy Roman Empire states had princes that were more like, dukes or something like that. And Frederic over in Dynasty quest is technically a prince iirc. Of the Grand Principality of Ostland.
I suspect the meaning is rather close if not equivalent to the rank of either duke or even as little as marquis. Probably not as low as Baron but who can say.
On this prince debate from before the update, a few thoughts:
- in our history, the word prince comes from the original title of Gaius Octavian Caesar, better known as Augustus, first Emperor of Rome. Rome had been a republic for a long time after it had driven out / killed it's last kings, and their elite (oligarchs) had a strong cultural aversion to the concept of having a King (monarch) again. That is partly why Caesar was murdered. Augustus, when he took over, played a polite fiction that he wasn't a Monarch, dictator for life, or tyrant. No, he was a man that upheld Rome's greatest traditions and upheld the Republic, while serving merely as First Citizen, the
Princeps Civitatis. In reality, he was the 'power behind the republic' and effectively ruled as a monarch, of course, but the polite fiction held for some 3 centuries. Augustus was also a honorific title he was given, meaning something along the line of 'the venerable'.
- the conflating of names, honors and titles from Roman period to later periods is influenced by this. Imperator (military honorific for commander / victorious commander, later a title used by the rulers to emphasize their military role) became Emperor. Princeps became Prince. Caesar became both Kaiser and Tsar, among others. Dux (military commander) became Duke, Dodge, Duce, as well is still in use in some school systems as honorific for the best student of a certain class. etc
- Prince has been a number of roles in the nobility. It can be a member of the royal family. but there were also states which we know as sovereign Princedoms, which effectively is just a king who uses prince as title instead. Monaco and Liechtenstein are 2 examples, 2 sovereign states that are still ruled by a Prince. There were also non-sovereign princedoms, which basically means that a duke uses prince as title instead. These were surprisingly common among both the French Kingdom and the HRE. Here it was basically a way to give a duke a more prestigious title without giving them any actual power.
- some princedoms were really countries, but for example the Dutch monarchy still uses Prince of Orange as title for the royal heir, even though the former princedom of orange is basically a municipality in southern France that they have very little connection to in practical sense.
- the Brits still do this by calling the heir the Prince of Wales. Wales, as I understand it, was called an princedom before being conquered by English kings, but their own title for their leader in their own language may not have had the same meaning. I don't know.
- during the Italian Renaissance, Machiavelli describes any autocratic rule of a city-state as a prince. Regardless of the title they use, if that ruler was from an ancient lineage, an appointed ruler by a foreign power, or someone who through scheming or force of arms had taken power.
- then, there are all the various traditional titles in the rest of the world, which often get lumped under 'emperor, king or prince' in western description as closest analogue, but which probably aren't a good fit because of different traditions, cultures, power distributions, political and religious culture, etc. Frankly, I know way to little on this, so it's probably best if I just don't put my foot in my mouth here.
- Thus, there isn't really an answer to the question: how to address a family member of a prince? There have been so many different ways that someone can be a prince, and even if they are a prince by similar means then the way of address changes by time, by dynasty and by country. If by virtue of close kingship to a king / monarch? Probably a prince. If by kinship to a ruling Prince? Propably a different address, to avoid confusing the ruling Prince with his brother / uncle / distant cousin that might start getting ideas above their station. Then again, you might say
Prince of Kiwiland to the ruling prince, and
Prince/Princess Joss to the family members.
As I recall, though I don't know if this is correct and it might just be fan-material or something. Perhaps from Imrix's quests, though I really do not know.
- Ulthuan's 2 classes of nobility (prince and noble) originate from the first Chaos Invasion. The nobility that existed before the Coming of Chaos was kept around, and are called nobles. They were your bog standard aristocrats at the time, doing all the things feudal aristocrats do (raise taxes, administer law both criminal and administrative, legislate, lead military stuff) But Anaerion had his best champions and generals given special equipment made by Caledor Dragontamer and the Priests of Vaul, and this was a purely military role under him. Some nobles were undoubtedly among their number, of course. The modern day class of Princes are those that trace their ancestry to these heroes and the greatest symbol of office they can wield is those ancient artifacts from this war. For a certain extent, princedom is considered a higher prestige class of noble then 'normal nobility' because of this connection to ancient heroes
- the Princes are the ones who elect a new Phoenix King, and the other nobility is not invited.
- Now, nobles and princes have since intermarried to some decree. Some princely families have lost most of their lands and incomes, while some lower noble families have increased these.
- still, the Princely families have their pride in their ancestors and some consider themself above the nobles, even when they only rune a run-down tower house next to a 'mere' noble ruling vast estates with the associate wealth and power.
- during an election for Phoenix king, some of these noble families that have grown in power and influence but are not allowed to attend, try and become the 'power behind the prince' by getting some kind of influence / leverage over a princely family, and then using their vote as a sock puppet for their own.
if this is correct, then Prince Teclis is correct, because the title of Prince is based on his descendant from Anearion the Defender, regardless of who rules their family fief or is the Head of House
