When humanity has already lost the war against the Xenomorphs, what remains? Set on a planet overrun by the savage alien species, the dregs of humanity cling to the protection of the mysterious siblings known as the Three Kings. But these warlords have a fourth sibling who is out for revenge - and the humans' remaining protectors are harboring secrets deadlier than the aliens outside their gates. The first chapter in one of the most epic - and darkest - eras of the ALIEN universe!
