At Ivy Town University, the Atom is forced to defend himself against a team of thieves who steal “the Luciferase” from his office. As the Atom seeks to question the one thief that’s left behind, the man appears to melt as if he were made of clay. A meeting is called at the JLA satellite where the Atom explains the Luciferase is a new form of energy and that the robbers each had a tattoo which Zatanna identifies as belonging to a cult called Fiatlux. In Ivy Town, Fiatlux hold a gathering where the leader, Gravesend, summons a demon called Hellrazer by using the Luciferase. The League arrive to investigate and find Gravesend battling the demon that has betrayed him.
