Gustav, now going by Gus, has gained control over everything his father owned after the Phantom seemingly disappears, including the old Opera House in London that was thought to have been abandoned completely after the chandelier incident, when really it had been bought out by the Phantom. Now, while he still visits Phantasma Coney Island, he spends most of his time in the Opera house watching as his empoyees bring in tour groups and tell them the stories of the Opera House, of his parents. Most only know about the Opera House, there were many fans of the play The Phantom of The Opera, that didn't know it had a sequel, that didn't know he existed. He worked at the Opera House, acting as a janitor, as the years pass by, his age seeming to have stopped completely when he'd turned 25 as he no longer grows old. His past and present shrouded in shadows at the events of his life, he just stays back and watches everyone come and go, stepping in rarely. That is, until he meets Crystal Frey...
