JSA

Jenny Lynn Hayden, twin sister of Obsidian, has a nightmare making her aware there is a problem with Obsidian. She calls her father, Sentinel, to tell him of her feelings. At the same time, all shadows in Milwaukee, former home of Obsidian, have completely disappeared.The JSA goes to the Milwaukee apartment of Jim Rice, the abusive step-father of Obsidian, and search it, finding a shadow sitting in a chair. When Sentinel begins to investigate it, he is sucked into the shadow and the rest of the city goes dark. A mass of shadows attacks the JSA, with Sand, Flash, Hourman, and Hawkgirl being taken over by them. As the remainder of the team is captured by their teammates and Obsidian, Sentinel finds Jim Rice in the Shadowlands, the source of powers for many heroes and villains, including Obsidian. Sentinel also meets Ian Karkull, who died 50 years before and whose energy has enabled the older members stay young for so long. Star-Spangled Kid manages to free Black Canary, who is being overwhelmed by shadows when they are driven off by a bright light, courtesy of Dr. Mid-Nite.
