Aaphobim

Aaphobim is one of the Elder Gods who created the Aether and the original planes. He is often known as "the Biologist", as his role in creation dealt mainly with the realization of life and consciousness.

During the formative eras of Ha'ther, Aaphobim helped Djot-ten develop APM and provided designs for the proto-humanoid APM matrix.

Later, Aaphobim became the sole creator of the material plane of Aaphobim, which was named in his honor. This, along with the planes of Ysenna and [one more here] would later be considered the only major material planes, though many lesser ones existed.
