Anton stared strangely at the girl, then glanced at Old Wizard Fiennes. Frowning, he asked in confusion, "Do you remember Auroro?"

The Old Wizard fell silent. He nodded and let out a deep sigh. "Of course..."

"Um..." He scratched his head in confusion.

He looked up at Anton. "I seem to have forgotten what she looked like."

As he spoke, he walked over to the fireplace, drew his wand, and tapped the relief above it. He rummaged through the pile of clutter within the relief before finally pulling out a book.

The Old Wizard silently flipped through the diary in his hands, muttering, "I don't remember the first part of my time as that stupid Pedro the Goblin's Apprentice, but that was because of Time Magic..."

He considered how to describe it, then said uncertainly, "It should look like a ball."

"!!!"

Anton blinked as he listened
