The Children of the Ophan are a religious group involved in the development of the Necrosi homeland, Sanctuarium.
With the help of their leader, Marlayne Praska, the Children of the Ophan spread word of the safety offered by Sanctuarium to hundreds of thousands of religious exiles who were persecuted for their beliefs. The refugees soon found a home under the guidance of Mihai Lucescu, exchanging labour for safety and freedom. Lucescu and Praska became leaders of a powerful legion of followers with a common hatred for their former oppressors (6.2.2).
