In the bottom tier were null shifters, who were unimpressive and made up the majority of the population. The realm had about fifty thousand people, and 99 percent of them were nulls. That was us. In contrast, the top tier consisted of ABOs. Betas were the most common ABO. They were the realm’s soldiers. Stronger and faster than nulls, they had extended lifetimes but couldn’t shift. Dick was one of them.
