The Reliquary of the Holy Blood of Christ from the monastery at Svätý Beňadik, where it spoke to Ernst and subsequently saved his life and the lives of the monks inside the chapel during the Turks's firing upon the chapel. Ernst and Ludovic smuggled it with them out of Svätý Beňadik, sending the Easter Catafalque to Esztergom in its stead.

It also has communicated with him and has aided him at times since, causing the stigmata to appear and giving him the ability to be protected from and interact with spirits.

The relic's true powers, motivations and nature are still unknown.
