The Chief Wizard has a set of work rooms in the Palace which has to be available for inspection at any time by the Queen and her Council. This requirement is recent and was brought in after Brankaresh’s treachery. The work rooms are in the lower two tiers of the Palace, well away from the middle tier which is where the business of government is carried out. The Queen takes the view if a spell is going to go wrong, it can do so well away from her! There are protection spells on her rooms, the State Dining Room and the Council members’ offices so even if a Chief Wizard does do something disastrous these rooms are likely to be able to salvaged even if the rest of the Palace falls down.
The Queen holds parties for her staff regularly - Christmas, Easter, a summer do and an autumn feast (roughly equal to our harvest). Good food, music and dancing is expected from everybody. FNN would love to film these but extra strong protection spells are put on the Palace to stop them getting sneak filming in (and they would if they could). Eileen used to like attending these parties to the Queen’s chagrin as Eileen got out as many of the “official” parties the monarch holds for the nobility and any visiting dignitaries from planets the Kingdom is friendly with as the godmother felt she could decently get away with. The Household appreciates their parties and privately the Queen prefers them too as they are more informal and fun but she cannot say so.
