Exactly as it says on the tin. Involves AUs, crossovers, and many more.
Albion, by definition, is not a normal organization. Self indulgent short stories; OCs include the Albions and Seth's mum. Explanations on their existences can be demanded. Rated T for safety.
Seth dissects Oz's personality into components. Oz breaks. Seth/Oz. Part two of three. Rated T for safety.
After coming back, Seth has to deal with the sins of his past. Seth/Oz. Part one of three. Rated T for implied sex.
