Lux Veritatis (Light of Truth) is a secret 12th century Order of warrior Christian monks who hid the Obscura Paintings in the 1400's. Lux Veritatis dedicating itself fighting The Cabal. Konstantin was member of this group, and was trusted with two of the Periapt Shards. Konstantin tried to raise his son Kurtis to be member of the order, but Kurtis left. That action saved Kurtis' life, since years later Pieter Van Eckhardt killed every member of the Lux Veritatis.
