"The world is a labyrinth, and the true followers of Ubtao know the pattern that represents their life. When they die, they must recreate that maze, spell out their past for me. To be a paladin of Ubtao, a bara of Mezro, you must know more. You must complete the maze long before you die, look ahead to the pattern that will be your life in the years and decades to come."
Ubtao was considered to be the leader of his pantheon, despite the fact that he was the only power within it. Other beings worshiped by the inhabitants of the jungles surrounding the city of Mezro: numerous spirits of nature, minor gods, and the essence of the Jungle itself – all were various aspects of Ubtao.
His biggest foe and antithesis was
Eshowdow, born from Ubtao himself. Due to the nature of Eshowdow, Ubtao was incapable of perceiving the Shadow Giant and could do very little to protect his domain and devotees agains the dark antithesis, which would prove his downfall. He had only one other enemy: Sseth, the Great Snake, a deity of yuan-ti and an aspect of Set.
During the Shadow Epoch of the Blue Age, the gods and the primordials fought for dominance. This Age came to a sudden stop when the primordial known as
Dendar the Night Serpent took the sun out of the sky. Eventually, the Elder Gods won the fight when the primordials were betrayed by one of their own: Ubtao the Deceiver.
Ubtao made an agreement with the rest of the Faerûnian pantheon to guard the Peaks of Flame for the day when Dendar the Night Serpent would pass through and end the world. She was said to be trapped behind a gargantuan iron door that sealed the Realm of the Dead and the serpent primordial away from the world. As reward for this service, the other deities granted him sole control over Mezro and agreed to leave his lands alone and never to spread their own religions there.
