Mamoth

Mammothi are a race of sentient organic starvessels that exist all across the Physical Realms. They were created by Adonis, Titan of Life, as a fusion of both mechanical and biological matter. They sailed freely through the stars, receiving sustenance from both starlight and various nebula.

A mammoth is a starvessel like any other, only with independent thought and feelings. They possessed their own individual codes of morality, and were as varied in personality as any humanoid. They are born through a complex biological and mechanical process very similar to the reproductive cycles of animals. When a mammoth becomes pregnant, they carry their newly developing off-spring internally, typically deep within the core of the vessel. As the fetus progresses, the newly growing mammoth slowly shifts to a dorsal position. After around six month's time, the new mammoth is then ejected from the mother.
