The 'Deathly-Hallows' tag currently exists and seems to be used often to refer to the Book (Harry Potter and the Deathly Hallows). But when I first saw it, I initially thought that it was meant for the Deathly Hallows objects (The elder Wand, The Invisibility Cloak and The Resurrection Stone).
Which is correct?
Both?
