Pode muito bem ter sido o avançado Time-Turner visto em Harry Potter e a Criança Amaldiçoada . Certamente possui a qualidade da "singularidade" que o Sr. Malfoy preza tão strongmente.
DRACO: The Time-Turner the Ministry seized was a prototype. Made of inexpensive metal. It does the job — sure. But only being able to go back in time for five minutes — that’s a serious flaw — it isn’t something you’d sell to true collectors of Dark Magic.
HARRY realizes what DRACO is saying.
HARRY: He was working for you?
DRACO: No. My father. He liked owning things that no one else had. The Ministry’s Time-Turners — thanks to Croaker — were always a little vanilla for him. He wanted the ability to go back further than an hour, he wanted the ability to travel back years. He’d never have used it. Secretly I think he preferred a world without Voldemort. But yes, the Time-Turner was built for him.
