Plot summary
A giant time-space tear called the Fault had been created by Black Bolt's T-Bomb, killing both himself and the Shi'ar leader Vulcan. The Fault becomes an immediate concern for both the Guardians of the Galaxy and the Nova Corps. They sent Wendell Vaughn, the first Quasar, into the Fault to scout it, given that his energy form would be able to survive its treacherous storms. Quasar soon finds that the Fault is actually a tunnel, leading to another universe which reeked of corruption, ruled by evil organic masses that had consumed their universe like a cancer. It is described as a Cancerverse, where "Life has won, Death has lost." He is captured by that universe's Avengers (called the Revengers), who plan on imposing their Earth on his, to enable their gods, the Many-Angled Ones, to continue to spread.[5][6]
