What sort of things would the Regent of the Realm spend their time doing, assuming they were not in fact as much of an utterly useless fuckup as, well, Fokuf?
In the version of Creation used in Kerisgame, the role of "Regent" does not exactly exist.
The Realm is run on a day to day basis by the Thousand Scales, which is headed by the Council of Imperial Ministers. These include such luminaries as the Grand And Supreme Shogun Of War, Cathak Cainan, and other such Imperial Ministers who head up their departments at the Empress' pleasure. So there's the Ministry of the Interior, the Foreign Ministry, the Ministry of the Exterior (which handles Satrapies), the Minister of Eugenics...
All of these figures are currently plotting against each other like scorpions, forming ever-changing alliances, using the Imperial Ministries to expand the influence of their houses without being so obvious about it that one of the others can shame them about it, hiring parties of young Terrestrials to sabotage their rivals, and generally acting like very suitable patrons for a party of Dragonblooded PCs.
The figure who is officially in charge by precedent is the Daimyo of the Treasury, who is the first of the Ministers and prime advisor to the Scarlet. The role traditionally goes to a bean-counter who can be relied on to keep a very close eye on all the funds and make sure that the Empress always has enough money before engaging in any long term wars or the like. It is an important role and the Scarlet usually desires someone who will, in fact, tell them that "No, we can't afford a war right now" because it's better to know that you can't afford a war now than have to humiliatingly request a special tax from the High Deliberative, who will extract all kinds of concessions from them". The Scarlet wants a hard-working, conscientious, detail-orientated individual to keep a track on all their finances.
This is not the sort of personality who really wants to have to deal with the Imperial Ministers full time. Unfortunately they now control the pursestrings since they can authorise payments in the Empress' absence.
The Ministers want money and want their budgets raised.
The Ministers want their rivals to have their budgets cut.
The Legions need paying.
Princess Nemone is trying to usurp the Daimyo's authority and has assumed control of the Imperial Household and the Scarlet's private purse, which she is
technically entitled to do as the (interim) Empress-in-Waiting.
Any new tax bills have to get past the High Deliberative and the Houses hate paying money.
There is a great need for more money because the Anathema are back.
The Daimyo very much doesn't want to get assassinated, and is therefore are living on a knife's edge, trying to maintain the financial probity of the Realm while
also not annoying anyone enough that they send more than the regular number of assassins after him while
also dealing with the fact that quite a few Dragonblooded are starting to go "Do we really
need an Empress? This chap in the Treasury can handle the beancouting. Why don't we just have the High Deliberative elect the Ministers if any die?" and then sometimes adding "Wink, wink" while looking meaningfully at a Minister they don't like.
The Daimyo therefore has fully dived into the "quick, hire Dragonblooded PCs to do things for me" school of thought since he can't be seen to be acting openly or someone might have him killed.
More than usual, I mean. All the Imperial Ministers are used to assassination attempts.
