Oh the fire wyrm 
The endless snaking and shifting
Gobbler of mountains 
Bears fangs 
Dog crawls
Men that fight
Are devoured
The rain that hits it
Turns to Mist
The fog that it cloaks itself
Allows it to move unseen
A mighty warrior
With Odin’s blessing
Can behead the wyrm
But beware its mate
Kill her first 
Or else 
You will be overrun
By wyrms
