The Imperial Family is the extended court of Kade family members, both Imperial and non-Imperial Kades who gravitate around the center of power, the Emperor of Regalia. Each Court member has their own agenda, likes and dislikes, and may join or publicly oppose a Noble Faction in the Assembly for their policies. Generally speaking, Several Kades are mascots (or leading members) of Court Factions, while others have no overt loyalty, but may still be interacted with in Progressions and bestow benefits indirectly to those they favor.
The Emperor is the titular and divine ruler of all of the Regalian Empire. The Imperial seat is currently decided on elective basis, though the Emperor has chosen to keep his choice a secret.
Emperor Alexander is a man of portly presence that has been Emperor for nine years now, with a single year interruption while Cedromar was Emperor. Emperor Alexander's reign is seen as one of competence yet opulence, intellectual ambition yet military decline, and enlightened centrism, yet a degradation of the power of the clergy. Emperor Alexander is generally looked upon favorably by the people, who believe he genuinely adores the people much like his predecessor Justinian II, but unlike Justinian II, Alexander has very little actual power and rules mostly as Emperor by consent than Decree, careful not to annoy or disgruntle the Nobility too much. Emperor Alexander enjoys the position of the sagely mediator, choosing never to lean to heavily into one ideology or the other, and remaining as a mentor of sorts with wise words of encouragements for those who break through to the inner courts. Emperor Alexander is completely above Court Faction politics, though the Court Factions whispering into his ears and showcasing him their favorites, does eventually get through to him, resulting in him granting favorable Court appointments to those favored by Factions.
The Princes and Princesses
The Princes and Princesses are those eligible to pass the Imperial Throne through their progeny, and are referred to as Your Imperial Highness. By Imperial Law, all Princes and Princesses are numbered, with 1st being the first in line to the succession, and further numbers being further removed from the throne. These numbers are merely for display nowadays however, as the Empire is now elective and thus the Emperor chooses a new heir to take the throne upon his death, as divined by the Everwatcher, who decided that it needed to choose its next Vessel instead of letting fate determine the heir. Women cannot become Empress of Regalia, however they can pass the right to inherit through to any male descendants they may have.
The Titular Princes and Princesses
The Titular Princes and Princesses are Imperial-Royal by relation to the Emperor, but do not actually have Imperial Blood, and thus have no claim to the Throne either. They are given the same title-address respects as all other Princes and Princesses of Imperial Blood (Your Highness), however are not seen as Princes and Princesses in the eyes of the Law or the Imperial Guard. They still wield considerable power in the Kade Family itself and should not be considered any less important than the Princes and Princesses of Imperial Blood.
Non-Imperial Kades are neither Titular Princes and Princesses, or Imperial Blood. Non-Imperial Members are so far removed from the inheritance and main line of Imperial House Kade that they merely have a Noble Title, such as Your Lord and My Lady. Non-Imperial Kades are still considerably useful to have the favor of, but they are not as important as the Imperial Blood members or even the Titular ones.
