King David Silver’s detection radius is too small. You can walk right into his throne room, hug the wall until you reach the vault, and take all of the private storages without him even noticing. It is kind of emersion-breaking that King Silver can’t see you when you are right in front of him.
His detection radius should be increased so that he can see everyone in the throne room.
It’s because King David Silver is so focused on his human seashell collection. It’s a very detail-oriented hobby because he makes them from scratch. It involves grinding the bones of his victims into a fine powder. Once powdered he sets the fine dust into a calcium-carbonate cement. The human dust is necessary for the protein content that it offers. You wouldn’t understand. It’s very important that the protein component come from a dead person. Otherwise it isn’t a human seashell.
