The last time signs of a crossing appeared, Harry crossed worlds within days. This time would most likely be the same.
Harry intended to use this crossing to conduct some experiments.

Besides that, the magical intelligence Hedwig could also determine whether magical constructs fused with the soul could cross worlds.
Harry felt that Hedwig would most likely be able to cross worlds. After all, his Chaos Magic could travel perfectly between the two worlds, and Hedwig, made entirely from Chaos Magic, should be the same.
Since these were merely experiments and did not require overly powerful magical constructs, Harry quickly completed them.
Both were jade stones the size of a fingernail, inscribed with simple Runic Glyphs.
