A battle beyond the stars didn't end quite as imagined. Legendary cosmic guardian and former Green Lantern Hal Jordan has unknowingly left a horrific legacy to the future. When Hal vowed to respect all life, he probably wasn't thinking of the nasty, acid-dripping, murdering Aliens -- and because he spared these vile creatures, he doomed the lives of countless others years later. Now it's up to current GL Kyle Rayner and the remnants of the defunct Green Lantern Corp. to clean up the mess made by his predecessor.
