Now the Dragon was the child of a dragoness mother and a unicorn father,so had a bit of a complicated personality.
As a child he had visited Damon's human homeworld when his unicorn dad had taken him along to visit his unicorn aunts and uncles who lived OVER there.
So he knew about the steam locomotives,steam ships,flying human balloons and the gatling guns and the other weapons the humans had been using on each another during he and his dads visit to the aunts and uncles.
Things had been so bad in the human world that a few of his unicorn relatives had elected to come with his unicorn dad and him
back to where the dragons such as his mother lived.
So 200 years had passed and the Dragon now had to make another momentus choice.
To stay and fight the rapidly approaching and growing human army this Damon human was coming with or take his elderly dragon relatives,frisky unicorns and the 500 transformed human-dragon-unicorn's he'd created with the spells he'd
learned over two centuries
and abandon this cavern and tunnel system
and head into the human world he'd first seen
200 years earlier with his unicorn dad.
In the end the snowballing size of the approaching army decided it for
the Dragon.
They could defend themselves against a few hundred human warriors but
it was becoming clear this human army could best be counted in the
tens of thousands.
Clearly this Damon human was intent on extermination and seizing the hoards and technologies the Dragon had copied from the other world.
And so the steam powered barrier shields to the other side were fired up
and a few hundred dragons,unicorns,hybrids and the odd human ally
abandoned the complex and
spent the night streaming into the world of Damons brothers and parents.
