"What is an elemental?" Lily asked.
"Oh, an elemental is a witch that has a close connection to nature and the elements, like water, earth, fire, and air. You'll find yourself easily accepted among nymphs, veelas, and other creatures that also value nature. This explains why you keep having all these accidents when trying out the wands. The things you've done now, with the fire and earthquake, you have the power to do those without a wand. When you use a wand, you lose control," Ollivander explained.
"Then, how can I use a wand?" Lily asked, distraught.
"Don't worry," Ollivander said, walking over to a table. "I've got just the wand."
When he reached the table, he whispered some words, and it carved out to reveal a compartment with a wand hidden in it.
"I call it omnis arboris, all woods. This wand has no magical core like the other wands. It is completely composed of trees. The trees it was carved from were somehow supernaturally weaved together, so that they were no longer separate trees. They became one tree, but with all types within. They even found properties unique of trees not native to the area," he said, gazing at the wand lovingly. "I've been waiting for just the person to give this to. For anyone but an elemental or a wood nymph, this wand would be nothing but a piece of firewood."
Ollivander handed her the wand carefully and took a step back, wiping a tear from his eye, "Give it a whirl."
"Okay," Lily said, holding the wand in her hand. This time the wand felt natural, like it had been waiting to come to her. When she waved it gently, the floor pieced together and a wind came through the windows and swept away all the dust.
Lily breathed deeply, "That's much better."
Ollivander eyed her carefully, "There is one thing I must say. This wand...is not perhaps sanctioned by, well, anyone. So if anyone were to ask, your wand is ten and a quarter willow. Anyone not looking carefully could easily mistake it for that."
"Alright. Will I be able to do normal stuff with this wand?" Lily asked.
"Oh yes, it will function as a normal wand would, it will just channel your unique powers much better," Ollivander replied. "Never, ever, try to use someone else's wand for any reason."
"Thank you for the wand, and I'll keep your advice in mind," Lily said, scurrying out of the store.
