An Arby n the Chief fic
The "Allknower" knows everything about everything, but he doesn't know why Arbiter, Master Chief, Cortana, and Greg are alive. He is convinced that they are some kind of manifestation of someone's obsession with the halo game, but that wouldn't explain Greg.
He studies them from afar to try and learn more about them, but when he realizes that they are starting to feel real feelings of compassion for each other, he decides to give them a chance at a real life.
He turns them all into what they are depicted to be, so Master Chief is a human with his armor, Cortana is the AI that goes inside his armor, Arbiter is a real life Sangheili, and greg is a real spider.
The story is about how they (mainly Arbiter and Master Chief) survive in the outside world and how their feelings for one another go deeper than just friendship.
