Kveldulf (in Videssian Kveldoulphios) was a Haloga who was captured and sold as a slave to Zoïlos in the city of Skopentzana during the reign of Stavrakios. When it became apparent to Zoïlos that Kveldulf was interested in worshiping the god Phos and becoming a priest, Zoïlos granted Kveldulf his freedom. Centuries later, a artistic priest who made icons would ask a Marcus Scaurus, an outlander and pagan to boot, permission to make a portrait of him since he had the features of Kvedulf. The mercenary though that if all Kvedulf was like the priest, it was no wonder the Halogai martyred him.
