The Evil Within All
Lachrima Libram Crystal
A small piece of Conclavus left over
A three foot long crystal with a width of about eight inches. The tips and terminus of the crystal seem to spin outwards and connect with each other in a strange spiral of connecting crystals that circle the main crystal three times.
This is an artifact left over from bygone days. This rather large crystal was actually only left within the Black Vaults of Conclavus. This large crystal was used in order to keep track of the massive vaults as well as what was within them. Using the crystal, people would be able to locate what they needed within the vaults and then go to the corresponding vault and unlock it.
The crystal is not technically supposed to leave the vaults, however, it has never been tested either. As to any other powers the crystal my have is up to massive speculation.
