After Sergeant Gregory Miller is sucked into a portal from a Forerunner Installation, he is taken another dimension in which he finds he is 2 years into the Clone War. And is oblivious to the fact that the Covenant have also invaded the same dimension that catches the UNSC's interest to follow. With enemies and allies from both dimensions against the common foe, an all-out war, more deadly than the Covenant and Clone War, breaks out across the galaxy. *Requested by Blue_Jay1002*
