Biography

Gerald

Gerald made his entire class discuss what feared them the most. He then quickly harvested the adrenal glands from their fresh corpses, in order to acquire the elevated levels of cortisol their utter panic had created. Gerald then injected himself with his own serum so that he might face his own greatest fear - his failure to save his wife from death from a fire.
