Luoc was an Irish missionary from the "St. Patrick's school" and lived in the 5th century. He was one of the first missionaries on Sodor. When he and his companions set out for Man in coracles, Luoc fell asleep. He was blown away from the wind and stranded in Suddery Bay. He was treated from the natives kindly, preached to them and built a church on the site, which later became Suddery Cathedral. He is remembered in the city's motto Luoc Sodoris Lux (Luoc the light of Sodor), and the coat of arms which shows him dressed as a bishop, standing in a coracle holding a crozier.
