Caldecott, an industrialist who has thrown himself and his industrial empire into the war effort, is being targeted by Nazi agents, who are being aided by his wife. Shade rescues him, and the pair spend some time discussing their familial connection before parting ways for several decades. At some point he retreats to a large house on a mountain just outside of Alice Springs in Australia. He and Shade meet again after Caldecott, dying of leukaemia, sends Will von Hammer to attempt to acquire some of Shade's blood. He reveals that he seeks the blood in order to prolong his life long enough to seek out the member of their family who is attempting to use arcane means to take over the world.
