[Harry frowns at that, because it isn't the first time he has heard of something like that happening. he lifts up a hand to adjust his glasses, still frowning about it. Harry hadn't actually thought the rifts could do something like this, but he can't help but note the similarities]

Sounds like rifts. One of the... other worlds I've lived in, they had these breaks in time and space called rifts, and they would sort of do and create things that were suspiciously relevant to what was going on like magic igloos during the winter. That kind of thing.
