Down Below and the Archon's Castle

In an underground fort, two children find a way to enter another world. There, they find friends in the form of a Sphere, a Rubbery Man and a Rock Man connected to the world below. The above world is controlled by an Archon, who collects aliens for exhibits. In this Wizard of Oz-like story, the children and their companions, battle the faceless thing that the Archon has become. Read this story to go on an archetypal voyage, the first of a seven-part series which follows the two children through their adult lives.
