Chapter 4 - State Rooms
Instead of going to a room which is in the State Rooms when the windchimes are in the Rose Garden:
now the windchimes are seen;
say "You find your way blocked by a phantom guard. Somewhere nearby you hear chimes.
As soon as you back up, he disperses into smoke again."
Instead of going to a room which is in the State Rooms when the windchimes are in the Rose Garden for the second time:
say "Again the sound of chimes, and the phantom guard that blocks your path. Somewhere there must be a ringer summoning him, protecting the State Rooms.
You have never known the Beast to put up guards before. It has always been enough for him to guard the rooms himself."
Instead of going to a room which is in the State Rooms when the windchimes are in the Rose Garden for the third time:
say "The chime summons the phantom guard again, preventing you from making any progress[if the Rose Garden is not visited]. If you cannot find and silence it, you will not be able to get into the State Rooms; it must be around somewhere[end if]."
