Anton, do you believe in light?

Anna simply could not understand why Ms. Olaro, this "self who might have existed in the past," insisted on crawling out of mirrors.

First it had been the mirror above the sink, and now it was a nuclear test pool.

Wizards really did not have many options for long-distance transportation: Apparition, Portkeys, and the Floo Network. That was it. Just those three.

There was not much choice.

A Portkey first required an object to serve as the transport medium, the Floo Network needed Floo Powder, and Apparition produced an explosive crack in space. The Rosier family alone had mastered silent Apparition in the Wizarding World. At least, no other wizard had been seen doing it for a thousand years, and Anton was the only outsider they had taught the technique to.

Even when wizards had other methods, those generally came from further developing these three forms of transportation.

For example, the Ministry of Magic's method of flushing people through toilets into its headquarters was actually a variation on Portkeys.

And the Little Waltz Phantom Traversal Anton specialized in was actually a variation on Apparition.

As for the Goblins, who excelled in the fields of time and space, Anna knew perfectly well that Pedro would never teach a human about either of those subjects.

Besides, even if he did, wizards could not learn Goblin secret arts.

Even someone as extraordinarily gifted as Anton, who had read so much from Pedro's memories, had only mastered one memory-sorting secret art, along with using the Biomimicry Charm to simulate the Moving Figurine, a little spellcasting trick that did not count as a Goblin secret art.

According to Anton, Anna could perform Goblin secret arts because Time Reversal had given her a superposed state of human and Goblin bloodlines. Hers was an extremely unusual case.
