Rufu Aoa /'rʊfʊ æ'oʊɑ/ was the founding king of Afanyu who abruptly lost control of his kingdom due to a wave of separatism. He remained the ruler of the large portion of his country, however, specifically the southern provinces, which would later become the Upper Kingdom. He was killed in battle by Drufos Lador in 1674 SR.

Rufu Aoa was suspected to be a legendary, with his life traced back to as early as the 15th CSR, although he himself never suggested this to be the case. Known under the name of Rufule, he was an important figure in Barzo, but then vanished from the city. He was later known as the Utbringer and played an unclear role in Darda, eventually venturing farther east to what would later become Afanyu, where he quickly gained power.

Having become the king of Afanyu, Rufu Aoa had his official biography written, but it was vague and largely metaphorical. Later research, however, revealed him to be a major player in Duls Settlements at least a century earlier. There are also indications that he crossed Ouna from Central Dantria and that he is originally from the suburbs of Gun Den. The latter fact was claimed by several people who knew him in Barzo, one of them Dilly the Dusty Fiend.
