Eventually finding the three spears and opening access to the forge, Raziel recovered the Water Reaver within and using its attributes he was able to open the crypt in the garden of the mansion where he found Vorador himself apparently awaiting the arrival of Moebius'svampire hunters. After revealing that the body of Janos Audron was within the crypt and could be revived by the recovery of the Heart of Darkness Vorador directed Raziel to its last known location in Avernus and directed him to the vista in the Library of the Mansion, providing him with the Library Seal to open the way.[Defiance][Defiance/8][Defiance strategy guide]
The Library Seal itself was a metallic circular disc with one face engraved with a design which featured a crow looking to the left while a dragon looked to the right behind it with its tail rising into a curve on the right side of the image. The reverse of the artifact was blank, presenting a plain metallic disc.[Defiance][Defiance/8]
The Library Seal is explicitly named as such in the inventory and its name is reiterated in the official guide.[Defiance][Defiance/8][Defiance strategy guide] The artifact is labelled in game files as "vor_librarykey". The corresponding lock, labelled as "vor_librarylock" includes the door, lock, and a copy of the artifact separately - the latter probably used for when the seal is inserted into the door. The door and lock textures reappear as part of background environment textures for the ruined mansion as "vorador_ruin10a-0010" and "vorador_ruin10a-0011".[Defiance][Defiance/8][Defiance/12]
The Library Seal is decorated with animal symbology which relates to Vorador - with both the dragon and the crow/raven previously associated with Vorador and making up Vorador's Crest in universe.[Blood Omen/6][Soul Reaver 2/3][Defiance][1][2] Other items in the game also use similar symbology with the Gold Half of Vorador's Crest created from a dragon and the Silver Half of Vorador's Crest created from a crow - with these ultimately combined to create the completed crest. The deleted Unused artifact is another that features a dragon and crow design, with this perhaps suggesting it was intended to be gained in the mansion - its file name and designation also suggests this possibility.[Defiance][Defiance/8][Defiance/12]
