Prologue

Colony Wars takes place in the distant future. Humans have further unlocked the secrets to the longevity of life and, as such, a population explosion across Earth forced mankind to begin colonization of the Sol System and, eventually, its surrounding star systems. As centuries passed, Earth and the Sol System were drained of all natural resources. The Tzar decided to pass a law, declaring that all outer colonies were to dedicate the majority of planetary resources to the survival of the Sol System, primarily Earth, as their duty to the birthplace of mankind and humanity's pioneering ancestors.
