When a mistake and a tangle of NID lies robs John Sheppard of his Air Force career before it can truly begin, he finds himself travelling the world, looking for a new meaning in his life.
He finds it during a public lecture done by the kind Doctor Carson Beckett during his trip to Scotland, And decides to apply for, and then receives a Student Visa for the one university the doctor regularly lectures at.
After volunteering for one of the Doctor's Gene tests, He suddenly finds himself with an invitation to join the Doctor on a "Top Secret Mission".
The only problem. It's run by the very Air Force that kicked him out in the first place.
Labeled as Gen, but you can add relationships if you'd like.
