Nobility is a large part of the storyline in Celestian Tales: Old North. It's customary to address nobles differently according to their status, and it's considered an offence, albeit slight, when such customs aren't respected.
The highest noble rank in the Old North is Count / Countess.
Formally, such as in written letters, they are addressed as [Lord / Lady] [Name] [of the] [Family Name].
At informal speech, they are addressed simply as [Lord / Lady] [Family Name].
Only three persons possess this rank: Lord Levant, Lady Belenus, and Lord Durandal.
Under their banners are numerous Barons and Baronesses.
Formally, they are addressed as [Lord / Lady] [Name] [Family Name]
At informal speech, they are addressed as [Lord / Lady] [Name].
Examples of those of the rank are Lord Robert and Lord Severin.
Nobles who have gone through training under a higher House (known as 'Squiring') are given the rank Knight.
They are formally addressed as [Sir / Dame] [Name] [Family Name], and informally [Sir / Dame] [Name].
Sons and daughters of Counts and Countesses possess this rank since birth.
Examples are Sir Abel and Dame Sophia
Sons and daughters of Barons and Knights start at the lowest strata of nobility.
They have no formal rank and are called [Master / Miss] [Name], sometimes with [Family Name] at the end.
Those of this strata can inherit neither land nor title from their parents, as they have yet proved their worth for the realm.
Arbiters are direct emissaries of The Queen, and they operate outside the noble ranks.
