The Sterkarms have plundered the borders of England and 
Scotland for generations.  Now in the 16th century, their way 
of life looks threatened.  For intruders have come, calling themselves
"Elves", bringing sweet gifts and honeyed promises.

But the Elves come from a polluted 21st century future.  
To them the 16th century looks like a paradise, ripe for the taking.
The only problem is the Sterkarms themselves.
