Upon entering, she sneezed as the musty smell entered her nose. This place had not been dusted in ages, she could tell as she fingered a table and found a thick padding of dust there.
A noise in the back of the store made Lily look up quickly. The sound was quickly followed by an angry exclamation, "Oh darn it!"
The source of the commotion was a man, perhaps the store owner, who came to the front when he realized he had a customer.
"Hello, dear. I am Ollivander," the man said. "A wand?"
Lily nodded, "Yes."
"Hmmm, let's try this one," Ollivander said, handing her a wand. "Pine, eight and three quarters."
Lily stood there with the wand in her hand, looking at the man, who was obviously waiting for her to do something.
"What do I do?" she asked.
"Oh, just whip it around!" Ollivander said.
"Okay," Lily flicked her wrist and the left side of the room was suddenly in flames. "Oh, I am sooo sorry."
She flicked her wrist again and the fire was extinguished and the room untouched.
Ollivander stared at her, "Not that wand perhaps."
Lily handed it to him, and he immediately replaced it with another wand.
"Try maple, nine and a half," he said.
Lily cautiously flicked her wrist, and nothing happened for a second. Lily sighed in relief, until she felt the ground beneath her shaking.
A moment later, there was a crack through the shop.
"Oh, no! What have I done, this is terrible," Lily said.
"No, this is marvelous!" Ollivander exclaimed excitedly.
Lily looked at him curiously, "What do you mean? You want a crevice down the middle of your store?"
"Oh, no. Not that. My dear, you're of the ordo tempestas," seeing she didn't have a clue what he was talking about, he elaborated, "My dear! You're an elemental! The first in centuries."
