The Challenge

Akinna has been sent to the past of a parallel earth in an attempt to save the humans that live there without the field of science. Her primary mission is to prove to them that the earth is not flat, but a sphere, so that they may progress scientifically and survive the natural disasters to come that would force them to leave their home for another across the 'uncrossable' oceans.

She must draw upon the philosophers and scientists of her own world's past to prove to these people with their own primitive technology this fact. Her time is limited, and her trip not repeatable. Everything rests on her knowledge and ingenuity to save their world.
