In House Goliath, Stimmers are established gangers. While seeking to achieve the peak of the Goliath's aspirational physical and musculature performance, they have become addicted to growth and combat stimms. Meanwhile, Forge-born, are gang prospects. They have not yet proven themselves to the Goliath, so they are not yet fully inducted into the Goliath Gang culture. As such, they often undertake the more dangerous tasks for the gang in an effort to prove themselves.
