- For Konstantin in other continuities, see Konstantin disambiguation page.
Konstantin was a member of Lux Veritatis. Konstantin was entrusted with two of the Periapt Shards, artefacts that can harm the Nephilim. Konstantin tried to initiate his son Kurtis into the order, but he left. Konstantin was killed by Pieter Van Eckhardt, who was looking for the Periapt Shards. The shards however were hidden, and set to be sent to Kurtis when Konstantin dies.
