In life, there are no certainties, but extinction is forever and when nature points its wrinkled finger at the oldest species in the universe, nature learns the Oredals are able to fight back.

  From an interview with Oredal Royal, Queen Tevi.
Oredals are creators of life. Many species that survive today, are the result of Oredals dropping a viable blob of material in a pool of goo, to see what would result. Among the viable creations, and because evolution is an extremely slow process, the Ordeals manipulated the genetics to force natural evolution ahead to create a better species. That is what Oredals do. In regards to your species, the latter pertains. That is why there are gaps in your evolutionary memory. The missing link you search for is the genetic manipulation, performed by my ancestors.
