For a millennium, the Crogenitors traveled the galaxy on their evolutionary mission, genetically altering the DNA of life forms they encountered to grant them new powers and abilities. Their greatest achievement was the creation of super-warriors: the Genetic Heroes.
Discovering the power of “exponential” DNA (E-DNA), extremist Crogenitors sought to make their ultimate soldiers even more powerful. But E-DNA was unstable, unpredictable, and ultimately uncontrollable. Hordes of mutated abominations broke free from their masters’ control. They were the Darkspore. And after terrible ages of war, the Darkspore closed in on the final Crogenitors.
