"Planet Heist, Part 7 of 8"
*Finally, Adam Strange has been reunited with his family on Rann. He also finally gets an explanation as to why Rann has been replaced with a supernovaed star. They feared the Omega Event, the coming of Starbreaker (the master of Sh'ri Valkyr from the previous several issues) and his desires to absorb the energy available to him by the zeta and omega beams. In order to prevent his ascension, Sardath hid Rann and destroyed the Omega Beam. Together, they discover that it was Valkyr who was behind the problems that Adam has been facing. They also realize that she's been tracking him this entire time. The Starbreaker is let loose on the suns of Rann and Vril Dox escapes back to L.E.G.I.O.N. headquarters.
With the Starbreaker gaining more and more power, the Omega Men and Rann's forces band together to stop him. But when everything is unprotected, Valkyr appears within the inner chambers of Rann.* Source: ComicBookDB.com
