Agora One - The Evolution Saga, #5

In 2578, it's been nearly 500 years since humans started to flee Earth.  They've now spread across multiple galaxies, thanks in large part to the SPEED drive, which hits velocities thousands of times the speed of light.  Earth is now an afterthought.  Agora One is a planet sized ship, the first of its kind.  It is a thriving, mobile trade port and vacation hot spot.  When news reaches Agora One that Earth has suffered its final calamity, some want to investigate.  What they find on Earth is far more stunning than anything they could've imagined.  The consequences of their investigation will impact Agora One, and possibly all life in the universe.
