   Summary

   The heralding drums of resurrection have begun their beat - for both the Dark Lord and the Old Ones. As Year 4 ushes in its many dangerous and supernatural intrigues, the newly renamed Harry Black - Prince of Slytherin - must focus on shaping Salazar's House and Wizarding Britain to his Vision amidst the Triwizard Tournament. With his coterie of family, friends, and allies, Harry must strive to work within the many machinations of Fate and Destiny to stave off the Dark Lord's diabolical desire for final rebirth, and prevent the rise of another Fate-marked Prince of Slytherin.
