the Safe requires "S.O.U.L" of 4 Animal Guardian.
And I think related Mosaics are as followed.

0-Scorpion (At the Middle-room of the Guest House)
4-Owl (At the Underground of Building that has the Safe)
5-Unicorn (At the Stable on the North of the Court Yard)
1-Lion? (At the Middle of Main Ballroom.)
   (the Shadow of Chandelier ovrelaped with Mosaic, so I am not sure exactly which Animal the Mosaic is.)

The big Safe is engraved with "C.R.O.W." on it.

And the room on the "opposite of the office(may be the room of the Rugald's daughter)" has follow dolls.

1 Cyan doll

3 Red dolls

3 Orange dolls

2 White dolls
