As you go normally through the game while recruiting most characters as soon as possible, you will miss several castle arrangements and locations of services and characters. Some rooms have different sizes as well, that you will never see if you play the game always in ideal order. Unlike other games this castle expands early, so different combinations are more likely if you have few characters.
The castle is updated as soon as you fulfill the requirements above. Dead characters will count. You can check the update by landing with your boat for a short sequence.

Trivia:
- At the banquet with the Lepant family and the pirates, the elevator is shown even if you haven't recruited Sergei yet.
- If you still posses a lv 1 castle after the defeat of Kwanda, the castle is temporary updated to lv 2 until you re-enter it.
- You cannot talk to Mathiu, Sanchez and Humphrey by Flik's arrival if your castle is still lv 1
- Some characters in town in Milich' domain won't talk to you at all, with a castle lv 1
- Because exactly 45 characters will auto-join your army in the game, you will always posses at least a lv 3 castle at the end
- While lv 4 is a requirement for some characters, it actually doesn't change anything except for the bath type (and the flag outside shown in the sequence)
