What is scarier then an intelligent creature
that's not human ?

Reptilian liveforms are most people's biggest fear...
It has been that way since the age of dinosaur's, when our ancessestor were ratlike and the big lizard's litteraly ruled the earth and mamals were nothing more then lunch........

Now, take this primal fear, and add to the mix intelligents, magic and fire......
And there it is: a Dragon......
Old as time itself, as powerfull as they are big and without emotions,
these creatures scare the living hell out of anyone,
except the fearless dragon slayer......
