This is the original lore that was written for the Goymayodimis. It may or may not be canon now as new lore is being written...
(It's best to watch Star Trek: The Motion Picture first to get an idea of the lore.)
The Origins of The Goymayodimi: After the V'ger ship exploded after Decker, V'ger (Voyager 6), and the Ilea probe fused into one being, a bio machine, it developed some distinct features. It morphed into an anthropomorphic dragon with feathered wings, a fur body and a fluffy tail. No longer human nor exactly a machine nor an animal, it became a fusion between to something new called the Goymayodimi. The explosion from the ship caused the new being to be teleported to the star named Polaris. The new being then called themselves Yama. A dark blueish Goymayodimi with the will of creating, so he created a new planet called Tekron and created life, his people, and a govern body within the newly created city called The Cleft. This government called The Goymayodimi Province of Tekron and he became one of The Elders.
