Cryptograph

Vault

Baroness Auravei's handwriting
Gift to Simon H. Sinclair (they shared a unique bond, unlike Herbert)
Auravei wrote letter to local professor, requesting "additional material for use in the creation of a cryptograph."
"I will lay down this burden and leave this stone, and the winding path of intrigue it precedes, for future generations" -Herbert

Prof. R. Willard could be the local professor, since Realm & Rune was published in 1905, which is about the right era for Auravei
