Antilas was a Videssian priest of Phos. He was part of a mission to Halogaland during the reign of AvtokratorStavrakios to convert the Halogai to Phos-worship. The mission was led by Tzoumas and also included Nephon and the Haloga Kveldulf who had converted to Phos worship while a slave in Videssos. The Videssians were given to violating their oath of celibacy, which left them vulnerable to a sorcerous attack by Grimke Grankel's son. Antilas, Tzoumas and Nephon were killed in their sleep.
