Supplanters

Everything has a season. Each living organism has a specific time of existence. Once evolution has commanded a change, it introduces into play it's agents to ensure that change. It is as natural as rain. The human organism has long lived past it's time on earth and evolution now demands change. If it were not for a select few that have dedicated their lives through the generations to stop this change, humankind would have been wiped out long ago. There is a thin line between what was and what will be, in between that line is where the Supplanters live.
