Bryns Williams was Rhys Williams' great-uncle. He originally worked as a sailor in his youth, but by the 2000s he was at the Ivydale Nursing Home. When he stayed up late one night, he was contacted by a mysterious entity who offered him youth in exchange for his help. Believing it to be the Devil, Bryns refused and was then killed out of spite.
