Ludvig is a martial arts master in Random Kingdom III, sifu/sensei of Ole, Alexander and Tammo. He is an instructor at the Youth Rehabilitation Center of City 03. "Chiron" is his online nickname, with nobody in the setting seemingly aware of his real name. He is a cyborg, having had his body from the lower torso downwards replaced with a mechanoid walker. Grampa Koch trained under this master (meaning he must be very old) and in his dying wish, told Ole to seek him out. More than one school; more than one master; the masters as elders, a council, a system of schools. * Sifu is an elderly martial arts master found in Rhûn. He grants the quests Get the Picture and Cherchez la Femme, which offer various possible rewards, among them the Blue Magic Shock Wave.
