High Priest

Place of Birth: Acahualla, Sargon Race: Feraerus

The High Priest had been living in Acahualla for a very long time – long before the first Great Chief of Acahualla and its incorporation into Sargon's hegemony – thanks to his Feraerus traits that make him immortal. He befriended Zumama whom he works together to build a giant robot nicknamed "the Big Ugly Thing," and he has been surviving numerous explosions caused by the robot's malfunction. He also acquaints Emperor, another notable Feraerus, and met at some point in the past.
