Crème de la Crème

Court Grandeur 10 is the ceiling, and it's mostly a money question - grandeur drifts towards a baseline set by your amenities, displayed artifacts and court positions, so push that baseline above 10 and wait. The Holy Roman Empire in 1066 makes the upkeep trivial: max every amenity (food, lodging, fashion, servants), fill the court slots with skilled characters, and display artifacts in every court slot. Needs Royal Court. Working on Hoarder feeds this directly.
