Gratiano de Veronese

Gratiano de Veronese was the last childe of the Lasombra Antediluvian. During the first Anarch Revolt, he joined the Anarchs to plot his Sire's demise. It is unclear whether or not he diablerised him, as soon after he accepted the role of Archbishop, he and his entire retinue disappeared. This gives Lasombra conspiracy theorists the idea that, maybe the Lasombra Antediluvian is not dead after all.
