Two groups of growing civilizations find themselves competing against each other while still being millions of light years apart. These two groups are the Humans and the Kierens. The Humans must struggle to break the bonds of gravity while the Kierens already equipped fully with magic can escape their own higher gravity slowly but with more renewability then what could be dreamed of.
Once above the sky, the race is on but all each team could do is throw pebbles at each other while the grueling task of traveling through space becomes apparent. Until the Humans find something worth bragging about.
