Manahan

"Manahan is an ancient name... a name best forgotten."

- Kaia

Long before the Original Twelve were created, there was the first God, Manahan. Manahan was created from both the essences of Arun and Shara, making him the most powerful of all the Gods created.

He witnessed the creation of the other Gods by Arun and Shara, and as such became curious and tried to create something of his own. However, he was young and inexperienced in creation, so he could only mimic what his parents did. He created an incomplete being,, who was neither a God nor a beginning of a race.

Even after creating Shandra Manaya, his curiosity was not satisfied. He sought to explore beyond the world he knew, and succeeded in breaking through a part of the barrier surrounding Arborea. This wrecked havoc across the lands and unintentionally formed the place known as "Agaia". His parents, Arun and Shara, realized the danger his curiosity and reckless actions posed to the world and imprisoned him and his creation in the newly formed Underworld. They used his powers to repair the damage he caused when the barrier was broken, and the world was safe once again.

While the other Gods knew of his creation and existence, he became someone no longer spoken of. His existence would never become known to the mortal races, and so he became merely an "ancient name best forgotten."

His creation, Shandra Manaya, later broke through the surface of Arborea and began an invasion using the Argons as her army. When she steals Sikander's Flame, she mentions needing it for resurrecting her creator.

Later developments
Destruction of Exodor's Black Core, initiated by Lumikan, and energies released seem to have at least weakened The Veil which surrounds Arborea. This allowed Manahan least to peek into Arborea.
