Mock Subjugation [1]

Yhien never made a significant contribution to history, but its death was part of something much greater. 

Then again, that was true for all powerful monsters and beasts. Their corpses led to the furthering of humanity's technology and understanding. 

Yhien made a decent contribution to the study of flying monsters but its main contribution was in the field of interspecies relationships among the monster races.

Humanity was able to learn about how the genes of the two parents were passed down and how they fought for supremacy to decide the offspring's final form. 

With the physiology of monsters, it was possible to create a hybrid of any kind if a monster was able to get their hands on the other party. It was as if they were created to be able to propagate regardless of circumstance.
