I hope copyright isn't a concern.... I actually know Ao from the Chinese turtle mythology. I didn't know there was a forgotten realm reference, although I love the name Ao. Either way I wikipedia'd it and found out there's two mythologies surrounding Ao. :)
The two for quick reference are;
"In Māori mythology, Ao ("daylight")
is one of the primal deities who are the unborn forces of nature. Ao is the personification of light, clouds and the ordinary world, as opposed to darkness and the underworld.
He is spoken of under many forms or manifestations, including Aotūroa, “enduring day, this world”, Aotahi, “bright day, world of light and life”. With his companions, Ata, “morning,” and Whaitua, “space,” Ao resists the forces of darkness."
"Ao (Chinese: 鳌, Áo)
is a large marine turtle in Chinese mythology. He was thought to have lived in the South China Sea during the time of the formation of the world. When the goddess Nüwa, creator of mankind, was repairing the sky after a disaster, she chopped off Ao’s four legs and used them as supports.
Another myth claims that Ao still lives and resides in the Bohai Sea, where he carries the three islands of the Eight Immortals (Penglai, Fangzhang, and Yingzhou) upon his back.[1]
He is thought to have been an influence on the later half-dragon, half-turtle figure of Bixi in imperial Chinese sculpture. Bixi was considered a son of the Dragon King who was able to carry enormous weights upon his back; figures of the dragon-turtle bearing memorial stelae are common monuments throughout East Asia."
