Pure Chimera

This the Pure Chimera that can you see into the cocoon in station Genesis in Bryce Canyon. The Pure Chimera are purely alien. They are not created through the Chimeran virus to make interspecies killing machines. The pure Chimera left earth around 60 million years ago after they lost a war againts an unknown alien species. They retreated to another planet but in 1908, a virus infused meteor that they launched at earth hit Siberia, causing infection through out the world. Towers that they built on earth before the first war were activated to open up a wormhole from their "new planet" back to earth to take it once again.
