Seems to have ruled the Votadini, south of Edinburgh in the early years of the sixth century. The name means “defender at the sea edge” and is the ideal name for the rulers along the cliff forts of north-east Britain. The genealogies show him as descending from Germanianus, the son of Coel, though this may not be a direct descent. He probably ruled a tribe who had some authority down the north-east coast of England, perhaps north of the Tyne, in the territory which became Bernicia. His nickname means “lightning,” which suggests he may have been a warlord with an ability to strike fast in raids and battles. Bulc was a proud and well established nickname amongst the Celts, and comes from the same word as the name of the tribe Belgae.540
