To the first question...the only thing noticeable was face value. An owl's feather in the shape of what would be used to fletch an arrow. I know what Cyril is driving at here, but my character has to remember.

Second question...Not even shadow magic can penetrate this room.

Thrird...Yes...since I rushed the scene...you can start your post from back a few moves where you had not yet entered the room...then proceed to put your self into the setting of the room.
