Medocenus (Al-Antidian: Maedoceno; c. 9300 - 12000) was an ancient pre-Tesklian king who ruled over the early civilization of Prosa. According to pre-Amilanian documents, Medocenus was the first individual to rule over a proper civilization during the First Era. Due to his status, Pnopleios gave Medocenus's name to the first of the three Al-Antidian historical ages.
