Y/n L/n has fought twenty four years of the human covenant war. Ever since his family and home were destroyed and now he has served with distinction in every battle he's been in. He's never known anything else but war and death in both sides now as the war ended and soon as he choose to be left behind to save his fellow soldiers from the flood. He accepted his fate but it didn't occur instead he is brought to Earth but not the one he knows. As terrorists are show he will do what he has always done. Feet first into Hell.

The Ark was destroyed and with it, the threat of the Flood for the Galaxy. The Covenant splintered and disordered. Humanity now has the chance to rebuild and strike back against anyone that may threaten them again. But it came at a price with the Sacrifice of the men and women of the UNSC. One of them being the last of the Humans to stay and fight to give the others a chance to escape. Sargent Major Avery Johnson was one of those men. he fought and died to destroy the Ark. But... he didn't. Our War Veteran wakes from the brink of death to find himself in a new world, in a new Galaxy. in a new war that he didn't need to fight in. Yet when a small village is about to be destroyed by robots... he just can't refuse. But when Magic aliens start swinging swords of light and lifting stuff with their minds, things may just get a little weird but our War Hero will create an unbalance that the Galaxy has yet to know is coming.

What does a Human-Covenant War Vet do when the enemy who haunted his very dreams are now in his everyday life? What is a man to do when he can't tell the difference between dreams and reality? What is he to do when face-to-face with his living nightmares? Not even he knows.... Alexander C. Franks, an ex-UNSC Shock Trooper, lives his life as a bodyguard for hire; leaving the Military behind with his dead brethren. His price isn't uncommon, if not cheap. He has never had a complaint from his employers outside of his militaristic thinking and attitude. If he felt there was danger for his employer, he put himself in harm's way. After a few months without work, Alexander finds himself standing in front of a female Sangheili looking for his services. After his years of fighting, killing, and mourning because of her kind, Alexander must debate whether or not the very profitable, and needed, offer he was given from the Sangheili will be enough to stop himself from killing the somewhat small female; or if he will be able to stop himself from reliving his past again....

Crashed on a strange world, Rook Baron and his team of 2 other Spartans must try to make contact with the UNSC.

Hence some of the funny timeskip scenes. see you all there!
