Up until age 12, Olaiya lived a normal and happy life. He had been thought the art of energybending by the high sages. When Olaiya was 12, Olaiya's Father left his family to defeat a great evil. From that point on, Olaiya began to hate the avatar.
Olaiya has grey energybending tattoos similar to airbending tattoos all over his body. He has dark eyes. He wears grey robes. He has a grey complexion.
Olaiya is determined and doesn't stop until he gets what he wants. He hates being told what he can or cannot do. He is also manipulative, and uses his both flattering and condescending words to control other people. He is very serious, though he does laugh, and smile on occasion. When he is upset he tends to act out; like a young child. Olaiya has used his manipulative prowess to gain hundreds of thousands of followers whom worship him as the "God of Death".
