Harry Potter went through a surprise Inheritence while on the run from the Ministry, he was in-fact Haden Pandore Slytherin. Last of 'The' Slytherin Line. When Hayden went to talk to Tom Gaunt they got closer and closer and 'Bonded' as time passed and the most respected couple took over the Ministry, they freed a Elemental Hybrid named Jackson Frost. The couple was entralled with their new found submissive and so that nothing would happen to him, they Re-Bonded, binding the three of themselves together. Fate had plans for this unlikely Trio you see. To take over the Ministry and fix it. To take over Hogwarts and fix that. Most importantly to keep the Magical Realm safe and 'Hidden' from the Muggles.
