Aa is The Father of Light, also known as the Everseeing. The three suns, known as Saan (the Seer), Saai (the Knower), and Shiih (the Watcher), are said to be his eyes, and one or more is usually present in the heavens, with the result that actual nighttime, known as truedark, occurs for only one week every two and a half years.
Aa is a beneficent god, kind to his subjects and merciful to his enemies. And, in the words of the narrator, "if you believe that one, gentlefriends, I've a bridge in Godsgrave to sell you."
In the Itreyan Mythos Edit
In all religions, there must be an adversary. An evil for a good. A black for a white. For folk of the Republic, this role is filled by Niah, Goddess of Night, Our Lady of Blessed Murder, sisterwife to Aa, also referred to as the Maw.
In the beginning, Niah and Aa's marriage was a happy one. They made love at dawn and dusk, then retired to their respective domains, sharing rule of the sky equally. Fearing a rival, Aa commanded Niah bear him no sons, and dutifully, the Night bore the Light four daughters~ Tsana, the Lady of Fire, Keph, the Lady of Earth, and finally the twins Trelene and Nalipse, the Ladies of the Oceans and Storms, respectively. However, Niah missed her husband in the long, cold hours of darkness, and to alleviate her loneliness, she chose to bring a boychild into the world. The Night named her son Anais.
Aa, however, was outraged at his wife's disobedience. As punishment, Niah was banished from the sky. Feeling betrayed by her husband, Niah vowed vengeance against Aa, and has not spoke to him since. Aa is still sulking about the whole affair.
As for their son, Anais, his fate remains a mystery.
It is said that it was during the first Great Tithe that Aa gifted his daughters dominion over the elements. To Tsana, his firstborn, he gave the rule of fire. To Keph, the earth. To Trelene, the oceans. Nalipse, the storm. In return, the daughters gave their father their love and obedience.
Aa is the primary deity of Itreya, and the most widely worshipped.
