A king or an emperor

Royal Court released on 8 Feb 2022. A king or an emperor opens the throne room. A feudal or clan ruler of that rank is who the launch court was written for. The court button on your character is the check for the government you are playing.
The hall has three parts: the throne room, court grandeur, and court artifacts. Inspired guests with a project in progress show on the left. Court artifacts is how you sponsor one, and how a displayed piece feeds the grandeur bar.
If the last kingdom or empire changes hands, the court artifacts go with that title. The items index is the slot list: large wall ornaments, small wall ornaments, furniture, books, pedestal items, and the throne.
Steam dates Royal Court to 8 Feb 2022. The store page describes a throne room for a king or an emperor, holding court, and grandeur.
Dev Diary 61 describes a royal court for every feudal or clan king and emperor, and measures grandeur from 0 to 100.
The grandeur bar

Grandeur is the bar on the court screen, marked from 0 to 100. The bar prints your current grandeur and your baseline. The header prints the level. Notches along the bar are the levels. While you sit under the baseline, grandeur climbs on its own, month by month.
The right end of the bar prints a world rank. Other courts are who you are being compared with. Above the baseline, opinion and marriage acceptance move in your favor. Under it, the store page calls the result the diplomatic cost of failing to impress. The court screen lists the modifiers for the level you hold. Higher levels also open extra council jobs. The council screen names the job.
The first grandeur level unlocks Hold Court. Holding court pushes grandeur once, on top of whatever the petitions themselves do. Displayed artifacts feed the same bar. Court artifacts is the throne-room slots and the named relics.
Since patch 1.19 a hegemony expects more grandeur than an empire. The hegemony guide covers that rank.
Dev Diary 61 says the first grandeur level unlocks Hold Court, and that holding court gives a one-time increase in grandeur.
Dev Diary 81 shows current grandeur, the baseline, and unlocked levels on one bar. Below the baseline, grandeur rises each month.
Four amenity controls
Four controls sit under the bar: lodgings, food, clothing, and servants. The name on each control is the level you have bought. Raising a control spends gold every month and lifts the grandeur baseline. The control prints the gold.
In the King of Georgia store image the four controls read Stylish Fashion, Lavish Food, Spacious Lodgings, and Endless Servants. Set them, then read the baseline on the bar before you leave the screen.
A court type and a court language sit beside the amenities. The culture's ethos decides which court types you can pick. Changing the type spends prestige. The button prints the cost. The court language moves the baseline. The language control shows that change before you confirm. You need to speak the language to take the leader's share of it. The grandest court of a language is that language's leader.
Update 1.19 added a Court Visuals tab to the Royal Court and a hand-picked Chinese court type, Dragon's Mandate. Patch 1.19 lists the other court changes.
Dev Diary 61 names four amenities: lodgings, food, clothing, and servants. Each higher level costs more gold to maintain and adds more grandeur baseline.
Dev Diary 81 says you choose between two court types from your culture's ethos, and that changing the type costs prestige.
Hold Court
Hold Court is the audience in the throne room. The store page is the moment you pass judgment while courtiers scheme and vie for your attention. You start it from the throne room once the first grandeur level is unlocked.
Three petitioners come each time. They can be courtiers, guests, vassals, or a neighboring ruler. You rule on the request in the event. Some rulings spend grandeur for a gain the event names. The event prints the cost.
The same throne room is where an inspired guest stands. Sponsor the project from the inspirations control. The gold is on the offer. Court artifacts is the path from that offer to a relic, including pieces an adventure inspiration has to find.
Dev Diary 72 describes Hold Court as a repeatable audience. Three petitioners appear each time. They can be guests, courtiers, vassals, or neighboring rulers.
Court positions and courtiers

The court panel has three tabs: court positions, your courtiers, and prisoners. A position is a job. The row prints aptitude and the bonus for the person in the seat. The footer prints the monthly salaries for the seats you have filled.
Court positions arrived with the Royal Court release. A Court Tutor improves education outcomes. When that seat is filled on a child's 16th birthday, the child gets one more education roll. Education and guardians is that roll. A Court Physician treats the sick at court and, with the expansion, adds grandeur. A Court Jester lists a chance of stress-relieving events. Master of the Hunt is the seat a falconry hunt asks for. Activities and tours is that hunt.
Read the row before you leave someone in the seat. The physician in the store image carries a warning that he is a powerful agent in hostile schemes against you. Intrigue and hooks is the scheme side of a court appointment.
Dev Diary 73 introduces court positions with the Royal Court update. A Court Tutor raises the chance of a better education. With the expansion, a Court Physician also adds grandeur.
Divergence on the same expansion

The Royal Court store page is also the culture work: traditions, languages, hybrid cultures, and divergence. The diverge window is where you name the new culture and pick an ethos, a language, a martial custom, and an aesthetic.
The window says a ruler can diverge a culture once, and that a divergent culture cannot have another culture diverge from it for 100 years. It prints the prestige and who will convert. The cost on the button is the one for this culture.
Hybrid culture is the other decision, the merge of two cultures already in the realm. That decision needs Royal Court or Khans of the Steppe.
The Traditions tab on that window is the list you keep or drop. Culture traditions is the pillars, that tab, and reform.
