"Ssssspock hissed happily as his genetic scanner locked on
something with knucker dragon DNA in it on the evolved planets
surface.
That something is you! "
Not only you,but the other 6 billion humans running around on
the planet formerly occupied by the dragons.
Naturally this puzzles the crew of the Pythia but
Ssssspock ,being the thorough firedrake he is (didn't you
know knuckers are 'Earthlings' and firedrakes came from out there
somewhere?) uses his skills and scanning equipment to scan for the
nearest living relatives of these homo sapiens.
The results
chimpanzees 95 % homonid DNA 5% other stuff DNA
homo sapiens 95 % homonid DNA 4% modern dragon 1% primeival DNA
which explains why when you went dragon you ended up on all fours
rather then walking about on two.The 1% of the 'Olde Tyme Dragon"
did it to you
So whilst you and the other 6 billion potential monsters on Earth
went about your affairs the Kapitain and others aboard the
Pythia discussed the implications of turning humanity into their
own species.
So it was you were staggering along the path back out of the area
when you came across the 'Egg',a landing craft the Pythia
used to get her folk down to a planetary surface.
As you watched a huge 9 story tall oblong object descended from
the skies,with strange alien markings on its side you did
not recognize,or so you though.
For as the alien craft got closer and the markings became
clearer and easier to read,some reawakened knucker dragon
part of your brain told you what the symbols meant.
