Tech Δ is a Delta Human from Earth. Prior to the Human/Galvan war, humans were an extremely powerful species with high aggressiveness. Because of this, the Galvans feared that they would one day pose a threat to the intergalactic community and began a war to eradicate them. All war efforts failed miserably, forcing the Galvans to engineer a genophage that mutated humanity into its current form. All evidence of the war and the human's original condition was covered up.
