The Marathon Story... The Final Screen

For seventeen years the renegade Pfhor scoutship
jumped between the closely packed stars of the

Probes were contructed and launched, with engines
and instruments whose sophistication would have astounded
both the Pfhor from whom technology had been
stolen and the human programmers of the AI whose
mad genius had directed their fabrication.
The outlines of continents were mapped, and along
them the radioactive ruins of ancient cities
were discovered, buried under the shifting
sand and rock of a global desert.

The tireless, nearly immortal cybernetic crew of the
ship were the genetically engineered descendants of
the dead world below- the first of their race in
a thousand years to return to their ancestral home.  
They came to search through the devastation of the
ancient war in which they had been enslaved,
