Royalty and Nobility
Generally speaking, Nobles have a title designating their social status, such as Duke Nozzle, Count Vinny Doombats, or Viscount Caesar Borgata. Other likely titles would be Baron, Earl, or Marquis. The word Lord has been used for units who are not Royal or Noble.
Since no known Royal are Casters, it may be that these two groups are mutually exclusive.
Known Royal Units
- King Saline IV - Croaked
Known Noble Units
- Count Vinny Doombats
- Viscount Caesar Borgata
- Archduke Ferdinand - Uncroaked, Destroyed
- Duke Nozzle - Croaked
Royals can probably only be created in a capital city, while Nobles can be created in any city which is part of a side led by a Royal. It probably takes longer to create a Royal than any other type of unit, though Turnamancy can accelerate this process.
It's possible free will is a innate trait to Royals, as most of the non-Ruler royals are described as ornery and contrary to their progenitor's wishes.
Many Royal and Noble Characters (especially Prince Ansom before his Decryption) believe Royalty and Nobility are the signs of Titanic mandate to rule. In fact, the purpose of Royal Crown Coalition was to defend this belief against Stanley, who believes Titans favor those with the Arkentools.
